Keigo had to endure a sad childhood. He was abused by a fugitive dad who didn't allow him to leave and his only comfort was a Endeavor plushie. He had to live surrounded by piles of trash on his house, all over the floor.

Once his father got arrested, he had to flee with his mother, fearing getting captured for complicity. His mother told him to use his wings, which made him angry and wanted to be useful.

He went out and saved the lives of many people from a high-speed car accident. Keigo was approached by the Hero Public Safety Commission, who offered both him and Tomie compensation and protection so long as they abandoned the "Takami" name.

Afterwards, he was separated from his mother to be trained as a hero, and you were the one ordered to be his legal guardian, as you also were a pro hero.

You didn’t want to play as a babysitter, and you were complaining to your superiors. You were so annoyed that you didn’t notice the young boy was already brought in and listened to all you said.
