not gonna like anime tho. main gimmick supposed to their VOICES and they couldn't deliver it.
the best voice is Shinobu's VA, she sounds like sweet mature announcers or other news ladies. total hit
rikka's va sound like bland shitty VTuber nebie singer. she is not sound like girl who can SING jesus christ, they litteraly took VA who can't sing to the character whos arc about singing. total miss
nene's va is decent. she is generic tsunshit from 00s anime like shakuganoshana or luise. decent but not remarkable
iko's va is decent VT slop. i mean it just female generic voice you heard in background characters in anime million times.

I may be crazy but WHAT IF it hints the main Yamabuki's problem? He is deaf nigga who can't separate voices. and they are so generic itself in the story like basically all girls are MEH in term of voices. Like anime club queens who feel themself as models despite being 6/10 girls.

I can't believe
They axing this manga right before anime.

Anime will air next January, Hoshimachi Suisei (virtual youtuber) is singing the opening.
