Kōichi Minamoto (皆本 光一 Minamoto Kōichi) is the main male protagonist in the series. He is the commander of a Special Esper team called The Children. He was the first commander that "The Children", Kaoru Akashi, Aoi Nogami and Shiho Sannomiya, liked. I-009 showed him a vision of the future in hopes that he can change it.


Usually seen with a suit and glasses. Minamoto is a fairly tall man with dark hair and light colored skin. He is also considered to be rather handsome by many of the female characters.

Personality Edit

While good-natured and tolerant for the most part, there are times when he is pushed over his limits and comically displays an enraged Fist of the North Star-esque demeanor, complete with quotes, inspiring fear even on his superiors or The Children themselves. After the timeskip, Minamoto is assigned as supervisor to several other teams who act as support – "The Shadows of the Children", along with "The Explorer" and "The Sleeping Snow White." He also starts developing romantic feelings for Kaoru, although he keeps repressing them out of his obligation to properly guide her and his will to prevent their tragic fate.


Just like The Children under his care, Minamoto also experienced the sadness of being neglected for being more capable then those around him, as during his childhood, because he was too intelligent, the other children could not stand him and he had to attend special lessons in Comerica, away from his family.


Being good looking and usually more kind and responsible than his peers, Minamoto earns the affection of several females during the course of the series including The Children themselves who openly express their will to marry him once they become adults on several occasions and get angry on him when he gets too close to any other woman. Beside leading and raising the girls, his main concern throughout the series is toward averting the precognition of a mortal showdown with Kaoru in a war-torn city during Hyōbu's esper-led war against normals a decade in the future.

Abilities Edit



  • Kōichi is named after Hikaru Genji (光源氏), the protagonist of the The Tale of Genji, who received the surname "Minamoto" upon being stripped of his royal status.
  • In one of the initial pilot chapters, Kōichi was a level 7 esper whose ability was the capacity to nullify other espers' powers, similar to Andy Hinomiya in The Unlimited - Hyōbu Kyōsuke.
