Junpei Shiroyama

Voiced by: Takahide Ishii

Third year in high school. He is living an ordinary student life without any special skills or clear goals for the future. His only hobby is to grow vegetables on the veranda at his house. He usually tends to stay away from people, but whenever he is with someone, there are short flashes of the power he carries.

Ryusei Midorigaoka

Voiced by: Takeo Otsuka

Third year in high school. He usually comes out at the top of his class. He admires Momoya extraordinarily and takes voluntary supplementary lessons. Prideful as he is, he is giving everybody but Momoya an attitude. When they were younger, he and Shiroyama were good friends…

Yurio Mizukami

Voiced by: Shohei Hashimoto

Third year in high school. A young, pale man with a weak constitution. Within the school he gives off a strong impression of being dark, but his advantage is that he looks rather neutral and is rather popular. He has roughly 20,000 followers on Instagram. Their types are completely different, but he gets along well with Kikawada.
