Band, I Can Travel Ten Years Later

Ren Tsukimura, who just wanted to lie down after time travel, learned of the tragic death of his best friend Rika Moriwa due to a premonition nightmare. Returning to the starting point, he must avoid the future and rewrite the other party's fate. It's just... "I'm not dreaming, but am I really traveling ten years into the future?" "Only by dying can you return to the present?" The moment he met Ruine again, Tsukimura Ren knew that the idol path would definitely not work, so he had better find a way to get Rika to form a band!
