The System Gave Me a Broken Skill by Mistake and Now It Is Too Late to Fix It

Kazuha keeps waking up in the same day, with a broken crystal in his pouch and magic traces on his hands. As a space crime scene specialist, he can read rooms after spells tear through them, but each loop leaves his memory less steady and his sense of self more thin. The game center regulars are the only people who still feel real to him, and his rhythm game reflexes become the key to reading a pattern that magic cannot hide. He is pushed into a sealed library, a court rite, and a forced title he never asked for. The borrowed coat in his desk and the scroll with his own magic already inside it keep coming back.
