コドウ・ティント
Kodou Tint
A mysterious transfer student who arrived at Torpas Shinkyoku Academy. Tint has two identical sisters who have the same appearance as her, their names are Azul and Verde.
All the triplets are so similar to each other, they cannot be distinguished by their hairstyles, voices, or gestures. The only way to distinguish between them is the color of the choker they wear under their clothes. Pelselthe had the idea to make the triplets wear their chokers as hair ornaments, so it would be a little easier to distinguish between them. Tint wears a red choker, Azul wears a blue choker, and Verde wears a green choker.
