Profile

The president of the Allied Hyakkiyako Academy's Yin-Yang Club.

To outsiders she's the student council president, but the intricate structure of the allied academy makes her role a complicated one. Her reputation precedes her as the president who dodges responsibility...but that's just who she is. Her many schemes appear self-serving at a glance, but behind the scenes, there's much more to the story than it seems.

Niya's full name is Amachi Niya. Niya's birthday is January 1st, and Niya stands 5'5" tall. Niya is voiced by 植田佳奈 in Japanese and Sung Yewon in Korean. Niya's hobby is doting on underclassmen and scheming. にぎりうさぎ drew Niya.
