Hashimoto passes by Akimura

Akimura and Hashimoto pass by each other.

In the year 2016, Hashimoto decided to take part of the last Hybrid Project ever at ONL due to unknown reasons. She originally worked as a care worker, but she appeared to be excited to become a egg donor. She was partnered with Shouta Akimura, and although he didn't want to talk to her, Hashimoto requested to see him just once. One day when Akimura was going on a walk, Hashimoto, who was five months pregnant, passed by and smiled happily at him. 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 that the two died shortly thereafter. To pay his respects, Akimura sent all of his money received from the project to Hashimoto's family.

It is later revealed that she thought that he was very beauitful, especially his hair, and named their daughter in honor of him.
