In the backyard, the tender green lawn glows with verdant shine in the sunlight.

At a round table in the center of the courtyard sat a young girl in a plain white dress.

She wore soft peach-blond hair and held a bunny puppet in her arms.

"Ahh

After seeing Alice and Sophia, the girl showed a warm smile and greeted loudly.

She is one of Alice's most familiar blood relatives, and her personality is as bright and cheerful as the sun - Alize El Cruznier.

With her immature sitting posture and warm and bright smiling face, Alize is like a lily blooming in the green grass, or a pearl dotted with jade chests, exuding dazzling brilliance.

Unlike some of Muna's Alice, Sophia snorted impatiently and sat down across the round table.

She crossed her arms and crossed one thigh, but because of her beautiful appearance and cold expression, Sophia's posture was not so much sassy as it was to highlight the coquettishness that did not match her age.

Sophia and Eliza, Alice's sisters, who are all too familiar, not only have very similar faces, but also wear the same style of dress.

But the difference in the color of the clothes alone is enough to make the two form a sharp contrast, and outline a strange scene in front of Alice's eyes.

Black and white, light and shadow, the two sides of the round table, the distance of less than one meter, but it seems to have fallen into two completely different worlds.

"That...... ...... now?"

The eyes of the two were focused on Alice, who was stunned, as if urging her to take a seat as soon as possible, which made her a little overwhelmed.

"Of course, it's an elegant afternoon tea party~~How is it~~ Isn't it very aristocratic lady~~?"

Eliezer said with gusto, her eyes flashing with excitement.

"Okay, don't pretend, let's start when everyone is here. ”

"What to start?"

Alice asked blankly, as if she was the only one present who hadn't been able to find the team channel.

"Information exchange and situation sorting, sister, you should also have a lot of questions about the current situation. ”

After hearing this, Alice nodded.

Indeed, as far as "crossing" is concerned, the pace of events they encounter is a little too fast.

To use a game as an analogy, it is to throw the player into the battlefield before the operating system has been introduced.

"Then ~~ sister and little sister ~~ if there is anything you want to ask, just ask~~ I know everything and answer it~~"

"First of all, where is this?"

The story should always start with the worldview, and Sophia's questions are decent.

"Here~~Located in the southern outskirts of the Zeseto Empire, an agricultural town - Silia~~ The lord is Count Lutgar Crusnier, that is, our father~~ However, even if you don't ask me about this kind of information, my sister and little sister should know about it, right~~?"

"The information I want to know is not this ......"

But Elize's answer seemed to be deliberately pretending to be stupid, giving an answer that the two of them already knew.

Alice, who couldn't stand it, pointed out sharply-

"Sophia probably wants to ask, did the three of us cross over?"

"Crossing ......?"

"Crossing~~?"

To Alice's surprise, the sisters unanimously expressed their confusion about this commonplace popular vocabulary.

"Eh, don't you understand? It's an old routine in novels and comic series! It's that the protagonist is struck by lightning, hit by a car, and then wakes up after he dies to find that he has returned to ancient times or to another world -- and so on, it's very common?"

"Ahaha~~ I don't know, I've never had time to look at these, and I've basically been working in the research institute all day long~~"

"Ah, my words have been on a mission in Israel for the past two years, and I have only arrived in country C for two weeks, and I don't know much about local folk entertainment. ”

"Okay...... When I didn't say ......"

Alice hung her head in frustration, and an indescribable sense of isolation came over her, and at the same time, she deeply understood that these two people were living in a different world from herself.

"But 'time-traveling' to another world...... Very apt to describe. ”

"Is it~~?I think it's the opposite concept, right~~"

"What do you mean?"

"If according to Sister Alice's statement, it is a crossing, then my identity is a 'physicist of the National Academy of Sciences', my little sister is a 'agent of a certain national intelligence department', and my sister is 'a student of a certain high school', right~~?"

"No, that's right, do you still need to ask. ”

"Then sister, little sister, let me ask you~~ Do you remember your former 'name'?"

"Oh ......! wait......"

“......”

Alize's sudden question made the two stunned.

As she said, Alice and Sophia racked their brains, unable to recall the "name" that once belonged to her.

I can remember a lot of details of my life, but the "name" seems to have been poached.

"Ahaha~~ Sure enough...... I'm the same, if someone asks me about my identity now, I will definitely answer yes - Alize El Cruise Nier, presumably my sister and little sister are the same~~?"

Hearing this, Alice suddenly remembered that when she confronted the bandits last night, she had not hesitated to report the name of "Alice El Cruznier".

This is obviously quite an unusual move for a traverser.

"Hmph...... It's just a name, maybe it's just a slight memory impairment, and it doesn't matter at all. Actually, it's possible that you've done something, Sister Eliza?"

"Ahaha~~Little sister, you overestimate me~~ If you want to eliminate the most core keywords such as 'name' on the premise of maintaining a complete memory, even the best psychologists on the planet can't do it~~?

"Eh, does the name matter?"

Alice was a little uncomfortable not being able to recall her name.

But that's about it, because for her...... It should be said that for almost everyone, a name is at best a "title".

Except for the use of exam papers and various registrations, the name will not have any impact on life at all, and even in daily conversations, the name can be ignored smoothly.

So, like Sophia, she can't understand the importance of Alize's name.

"Do you know~~?Whether from the perspective of physics or philosophy, a name is the most basic element and the most fundamental basis for judging the definition of a thing and its objective existence~~ More extremely, if there is no name, it can be directly determined that it objectively 'does not exist'. And then in the magic of this continent, the name also has a very important magical meaning, and countless magic and witchcraft are carried out through the medium of name, but of course there are many other prerequisites......"

"Well, I'm not interested in academic theory...... So, what kind of world is this?"

"If you want to use the earth as a benchmark~~ This may be a distant planet~~ Or maybe it is another parallel dimension, which is the other world that Sister Alice said~~"

"Huh...... On the basis?"

"There are too many bases~~ such as unfamiliar constellation arrangements, different ecological environments, unique physical laws, unknown material elements, and the most critical ...... Magic and magic. But well~~ The explanation of the details is a long story, let's put it first~~ It's just that I don't think it's necessary to figure out how many light years away from the earth is now. ”

After saying it in an innocuous tone, Arize spread her hands and shook her head.

"I see...... There really is no value in pursuing it. ”

And Sophia also agreed logically, and the topic came to an end.

"Why, wait, wait, why, it's important, isn't it? Don't you want to go back? There are families and friends on Earth...... Also, there are lovers...... Isn't it normal for people to want to go back? What's more, we were men until yesterday, and today we suddenly became a girl, no matter how you think about it, this is a huge problem that needs to be solved urgently, right?"

However, Alice was not as relieved as the two of them.

Although according to the usual setting in the novel, not many protagonists will want to return to the original world after crossing over.

In most cases, in order to avoid being involved in those troublesome and unpleasant psychological descriptions, the author deliberately arranges a tragic and tragic past for the protagonist, and creates a handsome image of "no nostalgia for the past".

The "boy" in Lovely Lisi's memory, but he has never experienced any magnificent life, neither psychological shadow nor hatred of society, just an ordinary student who can be seen everywhere.

If she says she doesn't want to "go back" at all, it's definitely against her will.

By the way, lovers, of course, do not exist...... It's just a lie from the petty vanity of the "boys".

"Hmm~~ I can't quite understand my sister's wishes...... After all, for me, as long as I can carry out my own research, it is not bad anywhere~~ If I have any attachment to the earth, it is that there is very complete research equipment there......"

It's just that in the eyes of the curious Aliza, this continent full of unknowns is too charming.

In fact, research equipment is at best a "handy tool". With some time and effort, she believes that she will always find a way to solve it.

You know, Alizze, who used to be a "researcher", is not purely theoretical, and it is also a pleasure for her to build the tools she needs from scratch by herself.

"You...... But I ......!"

"Sister Alice~~ I'll just say it...... We've not crossed over~~?"

Alice's verdict silenced Alice.

Indeed, the current situation may not be "crossing", because Alice has inherited nine years of memories and life from the beginning, and she was originally a girl.

It's just that the "boy" is a few years older than Alice, so that the "length" and "quality" of the two memories have a difference in weight, thus creating an "illusion" that the personality of the teenager should be dominant.

True, this is just an illusion.

The best evidence is that the two "sisters" in front of them, if you look at them from the perspective of a teenager, they are irrelevant strangers at all, and they are also the culprits who killed themselves.

However, Alice had no way to complain about the two of them, let alone resentment, just looking at the two of them, she couldn't suppress the love that welled up in her heart.

But in this way, it means that the memory of the "teenager" is just a long dream......

――Is it really possible to assert this?

"I ...... I...... Who am I......?"

After a long circle, Alice's mind returned to a dead end, and she involuntarily let out a mournful self-talk.

"Sister~~!"

Until a call from her sister lightly interrupted Alice's musings, and—

"Hey!"

A pleasant smell like toffee came to her nose, and when Alice came back to her senses, she saw a warm smiling face looking up at her.

"Huh...... Ai, Ai Eliez!"

Alice cried out in panic, for her sister Alize threw herself into her arms and wrapped her arms tightly around her waist with her two little hands, while the bunny's puppet was pitifully squeezed into the middle of their delicate bodies.

"Hug ~~"

Alyse buried her face in her sister's arms as if she were coquettish, and kept rubbing.

"You, you, what are you doing in the cold!"

The sudden intimacy offensive, the soft touch and the sweet body fragrance all made the "boy" part of Alice's heart mess up.

"Eh, hey~~How's it going?Sister~~~ Being hugged by a 'perverted Frankenstein', don't you feel disgusting~~?"

"This......! It's not ......."

Like a cunning cat, Alyse shows her delicate appearance vividly and exquisitely.

"What is my sister worried about, I don't really understand it~~ Who was yesterday's self, who was in the past, and even who was in the previous life, is it important? In the final analysis, human beings are animals that have no way to prove their identity~~? For now, for me in this second, you are my most important relative, my favorite sister, that's enough~~?"

It sounds like a strong theory, but it makes it difficult for Alice to refute the meaning. And at the same time, what makes Alice even more difficult to cope with is that from the angelic and lovely girl in front of her, the undisguised sweet words, and every word is full of strong love as if the bones will be melted, and a few words are enough to destroy Alice's reason.

- This, how can this guy be so cute!Ahhhh

With a self-defeating cry in her heart, Alice had no choice but to let her sister be spoiled in her arms.

“......”

On the other side, Sophia silently watched the intimate interaction between the two older sisters.

Maybe even she didn't notice it, her expression, which had always been cold, was showing a soft smile at this time.

"Little sister~~Why don't you speak~~?Are you jealous~~Ahaha~~ But don't worry~~ I also like my little sister the most, so let me hug ~~"

With that, Aliezel nimbly shifted her target and quickly approached in Sophia's direction.

"Sister Eliza, don't take the opportunity to stick to me...... God ...... annoyed"

Sophia straightened one arm and expertly pressed her fingers against Eliza's forehead, successfully stopping Eliza's little head from vainly trying to attack.

Seeing Aliez's carefree appearance calmed Alice's mind slightly.

Originally, Alize was a straightforward and innocent girl, and the former "researcher" may be very similar to Ariza in essence.

Alize is right, the warmth and satisfaction that fills her heart at this time is undoubtedly the unpretentious true feeling that belongs to "Alice".

-- But -- what about the other side?

In the body of the little sister Elize, there is an extremely dangerous man, and Alice, who has fought him head-on, knows that he is powerful and ruthless.

"Little sister...... You're like Alize?"

Recalling the attack in her bedroom not long ago, Alice asked with trepidation.

"I......'m sorry, Sister Alice, though I'm in a different situation than Sister Alice, but I'm far from you...... I don't have any nostalgia for the past, after all, 'I' have never had a family, but friends and lovers...... Occasionally, there may be, but they are all false interpersonal relationships established for the needs of the mission, which usually do not last long, and often need to be killed by hand according to the needs of the war. ”

"Extinguish, extinguish ......!?"

"It's not surprising, it's the kind of industry after all. ”

Then, in a calm tone, Sophia recounted the dark world she had set foot in.

In her description, the department to which she belongs is concentrated with many top intelligence workers from different countries.

Their personal information and resumes are nowhere to be found through normal channels.

Deaths, disappearances – and even worse, birth records have been completely erased.

Having lost their identity, they only lurk in the shadows of society, traveling around the world to carry out the most dangerous missions.

During this period, he will frequently change his identity, change his appearance, and even disguise his gender.

In order to accomplish the mission, he will also betray his friends mercilessly, and even kill the killer.

Sophia didn't touch on too much detail, just a general brushstroke, which was enough to shock Alice, it was a hellish day that normal people would never have imagined.

"In short, the current me, Sophia El Crusnier, has a precious true identity and a blood relative. Even if the 'he' used to be the real me, then for me, it is like a fluke from hell now, and I am so lucky, what reason do I have to worry about it?"

That's right, Sophia is not wrong.

Although there is a huge difference in degree, the "boy" has escaped every day of Spartan training, and this alone is gratifying.

But even so, the bitterness in Alice's chest still lingered.

"Sister Alice, I think you seem to want to take on some responsibilities that don't belong to you. ”

"Huh......?"

Finally-

Sophia's words hit the nail on the head of Alice's troubles.

Liability.

Because of the seventeen years of life experience that belonged to the "teenager", it was too vivid for Alice.

It was as if she had experienced it herself, and it had a profound impact on her emotions.

She felt that once she accepted the identity of "Alice......

Just a simple thought, it means that the life of the "teenager" for more than ten years has been denied.

――Is your young self really qualified to do so?

When she thought of this, Alice couldn't help but feel sad and uneasy.

If it were an ordinary eight-year-old girl, she might not think too deeply like Alice.

However, more than ten years of memories accumulated out of thin air forced Alice to become mature.

And in order to escape from this inexplicable sadness, in Alice's subconscious, a thought quietly sprouted.

"Responsibility...... That's ......"

That's right, as long as Alice takes the "responsibility" and firmly believes that the "boy" did not die from the flying disaster, and that he is the product of "he" after the crossing.

Then the "boy" can live as a "traverser".

Alice believes that she must take the "responsibility" to continue the life of the "teenager".

At the same time, this is exactly what Sophia said, which does not belong to Alice's "responsibility".

"Even if anyone were to be responsible for such an accident, it would be a scientific research institute that planned and built that kind of monster equipment, or a spy department of various countries that fought openly and secretly under the water...... Yes, it's like me, and some psychopathic scientist...... And Sister Alice is just a victim who has been involved in the incident, right?"

As she spoke, Sophia turned her gaze to Eliza across the round table.

"What do you say? Sister Eliza. ”

"Ah~~mm~~!That's right~~ The culprit is me who is right~~ Of course I will be responsible for this~~ So~~ Sister, and little sister~~ From today onwards, I will contribute all my skills and knowledge to fulfill all your wishes~~?"

Ariezel gave a hearty and reliable answer like this.
