Izumi Kamijou is one of only fifty people in the world who have the "Rough Stone", and he is also the world's largest user of the Rough Stone ability.
He has the same black-box-like ability essence as Sogiita Gunha, but unlike him, he exhibits a variety of ability phenomena and is a dual skill user (Dual Skill) of only one person.
The most powerful ability among them is LV5's fluid manipulation, a super power that can freely manipulate the direction and properties of fluids within a certain range around the body.
Because of this ability, Izumi Kamijou became the fourth among the eight people at the top of Academy City. Although his essence is as immeasurable as a cat box, compared to Sogiita Gunba, whose performance properties are a mess, Izumi Kamijou's abilities have high research value in various fields, so he received a higher ranking.
Izumi Kamijou, who was originally introduced to Academy City as an orphan and rough stone from outside Academy City, lost his memory for some reason and went on a rampage after waking up. He was finally stopped by Kamijou Touma and adopted by the Kamijou family, becoming Kamijou Touma's younger brother.
Since then, Kamijou Izumi's fate has been changed, and it has developed rapidly in a direction that no one expected.
The nature of ability, the unknown past, former partners, and blood relatives whose existence is unknown, puzzles appear in front of them one after another, and the blessed soul will finally reach the promised time.
