okay, so, just for fun i decided to research how the characters' names would be written in their native languages

what i got was:

Ἀστερίων (Asterion), Алтангийн Хэнбиш (Altangiin Khenbish), and Δομήνικος Παπαδάκης (Dominikos Papadakis)

but I wit a bit of a problem with Kota, as there is multiple ways his name can be written in kanji

so i was wondering it there was an official kanji for his name?
