number of people and/or who would attend their funerals (I'm so sorry, I was out of ideas and then this popped up xD), supposing the vampires are mortals for now:

mahiru: 200+

kuro: maybe mahiru's whole class, plus a few of his bros

misono: a shit-ton, including a lot of local orphanages, friendly neighborhood grandmothers, etc

lilly: maybe little, like, 40 or 50 (which is actually already a lot in my opinion), but these people mean a lot to him, and he means a lot to them

tetsu: all relatives + his new friends

hugh: 150+

mikuni: 10 people. no more, no less.

jeje: 1 (if he isn't dead already)

johannes: ... 0

licht: OH DON'T GET ME STARTED, HIS FAMILY IS PROBABLY GOING TO LIMIT THE VISITOR COUNT PER DAY

hyde: probs as much as misono, but more on the youth, not little kids and grannies

crantz: half of licht's, most likely

guil: probably his closest companions only, as he wouldn't want to publicuze it

tsubaki: his subclasses, maybe his bros if they don't hate him that much, the friendly neighborhood sushi guy

belkia: tsubaki and gang

higan: tsubaki and gang, maybe even licht

sham: t.a.g.

otogiri: t.a.g., plus a few of her encountered "fans", maybe

tsurugi: i... i don't want to think about that.

hello i'm alive. ironic, my chapter being so ridden with ded people
