(My) MC's family?|Gacha Club|My Ocs

In MC's family there are 7 siblings:
David-first oldest
Silvia(MC)-second oldest
Asano-third oldest
Felix-fourth oldest
Gazelle-fifth oldest
Zippy-sixth oldest
Gowther-seventh oldest
Except Asano who is "adopted", all of them are vampire meanwhile Asano is a human, but they all live in the human world, before MC had to leave for the exchange program.
Curiosity:
-Zippy and Gowther are twins like Beel and Belphie
-Their family isn't attached like other family because all of them live on their own, but if there is some problem/issue MC and David are always there for their younger siblings
-The brothers are really protective for their sister when it comes boys
-Gazelle get always mistaken for a male

Silvia=Lawyer(in the future in obey me she'll become a sorcerer thanks to Solomon)
Asano=Business man
