When she gains the ability to control minds, she can at last assert her will.
At Kawahara High School, young aspiring pianist Haruka’s plans to compete and perform are put on pause due to a fractured arm. Her aimless and lonely days are interrupted when she comes upon a fellow classmate being picked on. Stepping into the fray, she surprises herself when the bully obeys her command to leave them alone. She and the boy she saved, the good-natured Minori, become fast friends. And when Haruka goes home that day, she orders her shut-in brother Ren to leave his room — and it works like a charm!
But the next day, Haruka receives a letter from a mysterious so-called “Senpai”, who instructs her to go to an old storehouse after school. When she arrives, two upperclassmen welcome her as one of their own: another Kawahara student who received a superpower making up for their greatest weakness. As a new member of the club, she juggles her time between investigating the strange phenomenon and nurturing her blossoming feelings for Minori.
Which will win out in the end — her strengths, or her weaknesses?
