Mona: she isn't human at all, she seems like so (hence by Maria's[my persona's] evil form) but in a sense she is a shadow figure

Mio: She has experience in self defense.

Mao: he got rejected about 10 times. now being with a someone that I will draw maybe

Lily: She often goes behind Mio's back and just tries to sabotage her(and failing)

Florian/Mano: him being an magical boy, he is often mocked about the fact that he is represented by the Bell flower

Leo: Him and Florian being fashion designers they often argue about who's design is better, causing for Mio to hold back Leo as he is quite literally the type to take insults too far
