Akimura was thereafter explained to that Hashimoto was his partner in the project and that she had requested just to see Akimura's face once.

In the year 2017, Hashimoto went into labor, but right before the baby, Mikaze Akimura, was born, she transformed which left both mother and child in critical condition.
