"Do you like Ultraman?"
Jun Takano picked his teeth with a card: "I don't like Ultraman, who likes Ultraman in a serious person!"
"Then tell me, what is the card in your hand?"
Jun Takano glanced at it.
"Well, there is no great power in Utolaman Shikali."
"Then you say you don't like Ultraman!"
"Please, this is Utolaman, or the weak, pitiful and helpless Shikari."
Focusing on the world of Demon Change, the Multiverse, don't be careful about the timeline, and focus on books.
The protagonist pursues power, and he doesn't become Ultraman from the beginning, so don't get into it if you don't like it.
