i can't believe he took a book out of the chinese genshin advertising campaign which revolved entirely around "oh - you play genshin too? let's play together" lmao
Don't have the raws, but I would guess "Nayujan" is just Himari being mildly surprised at seeing Nayu, not her (nick)name.
I also reckon the supporters aren't the ones talking on the last page, but that it is still part of Himari and Nayu's conversation.
It does me well to see Masuda Eiji back at the helm of a manga again. His art has improved so much, but it's still got that distinctly Masuda Eiji style. I hope this one flourishes like Jitsu Wa did!
If this becomes repetitive after like 20 chapters I wouldn't be surprised, like other people have said...
Doesn't really matter because chapter 1 is peak and stands on its own.
