By the way, I forgot to add this to my afterword, but I consulted with my Japanese friend about Yayoi's name.
Apparently, Marujuu (even though that's what it says in the furigana) is not a name you'd find in real life. It's a fictional name. Even most translation stuff would give you Marushige using the same kanji, actually. But even the name Marushige is not a popular name, too! According to Forebears.io, only 70 people in Japan have the name Marushige. I dunno, man. I just thought this part was fairly interesting.
