Mondaiji tachi ga Isekai Kara Kuru Sō Desu yo? Wiki


A person who wanders around Little Garden. Kasukabe Yo's father, he gave his bedridden daughter the Gift [Genome Tree], which enabled her to regain her mobility as a result of its copying ability which activated from touching Calico cat. He stated that at one point he had fought Draco Greif, the leader and namesake of the alliance, and remarked it as being a foolish thing to do. At Volume 12, it was stated that he was the former leader who was once called the strongest man of No Name. He was also the one that restored the spiritual power of the Genome Tree when Kasukabe Yo lost its power due to her transforming into a Garuda.


Not mentioned.


By inference from his actions, he is quite a wanderer who likes to go around helping others. However, that also means having spent less time with his daughter. He also seems to look back on his life and recount things he has done to be either foolish or incomprehensible. Described by Garol to be a laconic person who would become very soft spoken when embarrassed or unsure but fiercely loyal to his comrades and friends.


Kasukabe You- Father & Daughter.

Garol Gundark - Seem to be aquanted in some way. Garol was suprized when he heard "Kasukabe" when Yo introduced herself. Also when he is holding the [Genome Tree] he is talking/thinking to himself---"that ojou-chan said that this was made by her father? He could only think of one person who could have done it and that person had been quite close to him."

Willa-o-the-Ignis-Fatuus - Saved her from a Stalker.

Maxwell - Responsible for defeating Maxwell and teleporting him out of Little Garden.


Years before the current story arc, Koumei had helped Ignis Fatuus with an irritating problem: Ridding her of a pesky stalker called Maxwell. Years after, Ignis Fatuus will meet his daughter and tell her about her mysterious father who frequently disappeared.


Genome Tree

There might be more Gifts but it is not revealed but hinted... like how he frequently disappears.


  • Going by the prologue of Volume 4, it is possible Koumei was the original owner of Calico Cat.
  • It was stated during his conversation with Baron La Croix that he wanted to meet his daughter if he can but for some reason cannot. The reason is unknown.
