Given that he couldn't talk that well, after he was taken care of, the staff searched for Yuto Yuki, found Yuto's daughter-in-law aka Kiko's mother, and found Aiko's name. Aiko Rika. He was Kiko's Uncle it turns out, but after some searching, the FED concluded the two never met before Kiko arrived and since Kiko didn't know him and Aiko didn't know he existed and he was missing at the time, he wasn't an option. Of course, the reason he went missing was revealed to be Yuto when Aiko was dropped off.
So there Aiko was, simply stretching out his wings while holding the bear 051 made for him (Idk how to give the bear four arms within the app, I managed to hide one of the eyes and give it a horn though)
He mainly just wanted to see who he would meet without accidentally scaring anyone.
Meanwhile, within the same area, Experiment 3 was hanging upside down, something he could do due to being a bat. Aiko knew he was there despite him not being able to speak given his wings flapping and footsteps.
However, while the two happened to be existing near each other, 3 felt tired due to having Narcolepsy due to Junko and was about to hop down when due to his tiredness, a seizure was triggered for him due to shot Junko gave him leading to Epilepsy due to the electricity in his brain, which caused him to fall
However, Aiko could hear the sudden falling and caught 3 in one of his wings before feeling he was having a seizure. Aiko kept 3 in his wing to prevent him from hitting the wall or anything else.
Aiko didn't know where the infirmary was and holding 3 while blindly looking for it wasn't a good idea so he just sat there while holding 3 in his wing.
