Ash (78)

Ash is an explained name as a credit on オワタP's 5th album あっしゅ＼(^o^)／. The official music upload doesn't list Ash is the description (Akita Neru and Yowane Haku appear instead), but the name appears in the video itself. It is known that the Benzene series of songs have encoded messages and have embedded clues, so the name may be a reference to that content only.
