Given that the artist has a fondness for depicting Adler as a he/him butch lesbian, I wasn't sure what I should tag this as at first. I ultimately went with my initial assumption of this being just Adler depicted as a trans man.
What's funny is Nayuta in canon has probably never seen Kobeni, but could still know her face from reading Denji's mind in his sleep. Good thing Denji doesn't ask many questions.
(Also, lol this is some version of Chainsaw Man where either Digital Circus was made before 1998 or it's at least 2023 but Denji's house still only has a CRT+VHS combo.)
