Time goes back to when Kuroko had just ascended to junior high school. On the first day of school for Diguang, Kuroko walked on the cherry blossom campus road, and there were various clubs on both sides of the road that were recruiting, but because of Kuroko's natural weak sense of existence, the club recruiters didn't notice him, and Kuroko also looked at the books in his hand while walking attentively. Kuroko walked to an open space, looked at the basketball club application in his hand, thought of the agreement with his friend Hagiwara Chenghao, and decided to join Temitsu's basketball club and meet with Hagiwara on the field. After thinking about it, Kuroko happily looked up at the clear sky, full of anticipation for the future.

On the day of the basketball test, there were dozens of new students in the gymnasium. Before the test began, everyone was busy making new friends, but Kuroko just stood quietly in the middle of the crowd and waited for the test. After a while, a senior arrived in the gymnasium, took the roster and began to call names and test in groups. When the senior read "Kuroko Tetsuya", Kuroko walked straight to the senior, but because of Kuroko's weak sense of existence, everyone didn't notice him, and Kuroko was used to it, just when the senior thought that people didn't come and planned to skip it, Kuroko said silently next to the senior, "I'm here." ”

The sudden voice startled the unprepared senior, and he looked at Kuroko in horror and said, "You...... You...... When were you here? ”

Kuroko looked at the senior and said indifferently, "I've been here." ”

The senior muttered to himself, "Why don't I feel it at all, it's too weird!" Then he divided the sunspots into groups.

When the test results were announced, Kuroko was divided into the three armies. For Kuroko, although it was expected, he couldn't help but feel a little lost in his heart, and his usually expressionless face also had a little dejected look, but Kuroko remembered the agreement with Hagiwara, so he cheered up again and walked to the three armies.

As soon as Kuroko entered the ranks of the three armies, he heard the senior say that he would announce the list of the first army. The news was like a bomb, and the crowd in the gymnasium instantly became excited, and all kinds of discussions filled the gymnasium.

"Did you hear that, someone passed the test and entered the first army! Diguang's basketball club is famous in the country, and no first-year freshman has ever passed the test to enter the first army. ”

"Yes, I've heard that it's impossible for anyone to enter the first army in this test! So I think it's very good to enter the Second Army! I didn't expect someone to join the army! So worshipped! "

"That's it, I'm so envious!"

"That's it! It is! I didn't even enter the Second Army! Woohoo......"

......

Kuroko listened to the various voices of envy, jealousy and hatred around him, although there was no expression on his face, but he was already as surprised as everyone else in his heart.

After the senior waited for everyone to be quiet for a while, he announced the list of the first army: Seishiro Akaji, Shintaro Midorima, Atsushi Shihara, and Daiki Aomine.

After the list was announced, the four people who attracted attention walked towards the first army one after another. The first is Seijuro Akaji, who is relatively short and has crimson hair, and although he has a gentle smile on his face, he has an irresistible aura on his body; The second is a tall, green-haired Midorima Shintaro with an indifferent expression on his face, but what doesn't match his temperament is a pink Hello Kitty puppet in his bandaged left hand; The third is the tall, purple-haired Atsushi Shihara, although his expression is lazy, his strong body and unattainable height are enough to shock everything; Finally, there is the muscular Aomine, with dark blue hair, who, unlike the other three, has dark skin but a hearty smile on his face, which makes people can't help but be infected by his enthusiasm.

The eyes of the freshmen in the gymnasium were all envious and jealous at the four people who calmly entered the first army. Although Kuroko looked at the four people who walked into the first army with an expressionless face on the surface, he couldn't help but envy and worship in his heart, and at the same time silently cheered himself in his heart, hoping that one day he could enter the first army like them.

At the end of school, Kuroko receives a letter from Ogiwara Narihiro, in which he tells Kuroko that he has joined the school's basketball club and encourages Kuroko to work hard together. After reading the letter, Kuroko looked up at the blue sky with a smile, and his heart was full of confidence in the future, and he was more determined to play basketball. Later, Kuroko also wrote back to Hagiwara Narihiro, telling him about his participation in the test and the entry of Akaji and others into the First Army.

After joining the basketball club and starting training, Kuroko trained hard in the third gymnasium every day, but the freshmen who entered the three armies of the basketball club together slowly began to enter the second army, and only he stopped. At the same time, Akaji became the vice-captain, and Aomine, Midorima, and Murasakihara were all selected to complete the summer all-high school competition.

One day after school, Kuroko received a letter from Ogiwara Narihiro, in which he told Kuroko that he had become a substitute for the team, and although he couldn't play yet, he was one step closer to the agreement, and encouraged Kuroko to cheer. Kuroko was silent for a while holding the letter, and made a decision in her heart. In order to have more training time, Kuroko asked the coach the next day to borrow the door key of the Three Armed Forces Gymnasium, so that the three armed forces could continue to train in the gymnasium after regular training.

Since then, Kuroko has often trained alone in the Tri-Services Gymnasium until late. Because of the unusually weak sense of existence of sunspots, many people only hear the sound of playing basketball and see the basketball rolling on the ground when they pass by the three-service gymnasium at night, but they don't notice the sunspots inside, and the legend that the three-service gymnasium will be haunted at night gradually spreads in the basketball club. In the end, many people were reluctant to stay in the Tri-Services Gymnasium at night, making the Tri-Services Gymnasium a place for Kuroko to train alone at night.
