Mana Shodo Gender: Female Age: 17 Grade: 2nd Year Ability: Space Manipulation A 2nd-year S-ranker. She has a serious, rule-abiding personality like a class president. Her grades are top-class in the school. Conversely, she is not good at flexible thinking and finds it hard to apply her skills; she feels this is a challenge but struggles to improve. She is patient and strict with both herself and others. She is skilled at delicate ability control and wants to use her power to help people.

Hikari Hanami Gender: Female Age: 17 Grade: 2nd Year Ability: Energy Discharge A 2nd-year S-ranker with an innocent and sparkling personality. A kind gal who treats everyone equally. She has a light way of speaking, but she is smart, good at acting with consideration, and often notices changes in her surroundings or people's emotions. Because she is resourceful, she has mastered her difficult-to-adjust ability with considerable precision. On the other hand, she doesn't really like her own ability, which could cause immense damage over a wide area, so she basically keeps her output low; it's said that no one has ever seen her go all out. She also feels pressure from being an S-rank, which is an object of public admiration.

Taiga Inomata Gender: Female Age: 18 Grade: 3rd Year Ability: Physical Enhancement A 3rd-year S-ranker, no one can match her in close-quarters combat within the school. She is physically strong and hates to lose. She loves beating men. She is very popular with the girls and receives a massive amount of chocolate on Valentine's Day. Her personality is rough, quick to act, and hot-blooded. She is not good at thinking and is an intuitive type; her academic grades are poor, and she is bad at following detailed rules. She controls her ability through intuition rather than logic. Because she acquired delicate control of her ability through patient and harsh training in the past, she acknowledges anyone who puts in effort regardless of their rank. She is actually good at looking after her juniors and has a big-sisterly nature that can't say no when asked for a favor.

Rei Amamiya Gender: Female Age: 18 Grade: 3rd Year Ability: Future Prediction A 3rd-year S-ranker. Cool, taciturn, and poker-faced. It's hard to tell what she's thinking. Due to the nature of her ability, there is very little she doesn't know, and since she can even control people's emotions to a certain extent, she has little interest in others. Conversely, her interest in unpredictable things or people is twice that of a normal person. Immediately after her ability manifested, she suffered from a state close to sensory hypersensitivity because she couldn't adjust the amount of calculation, but through training, she became able to control it and can now lead a daily life. Also, because people think she is predicting the future or reading minds (though it's really just prediction through high calculation ability), she is often kept at a distance, and she tends to distance herself from people to avoid being hurt by that.
