wow uhh lol as much as i REALLY wanted to, i found myself not giving a fuck about this shoehorned tragic backstory of a character that NO ONE asked for, from a manga about two childhood friends getting closer, neither of whom are THIS background character from the beginning.
with how much traction this manga is getting, an anime adaptation is entirely possible. regardless, this little detour was overall unnecessary, unless somehow Yami's story can tie into whatever themes Maruto is trying to present here in this story.
