Shiba Jiren, a time traveler who lost his memory. His Zanpakuto pretends to be a witch, a sword spirit that can rewrite reality but wants to reshape the world. A notebook studying the composition of the soul, the three merged into one - he became an outer god. He saved Haiyan, defeated the nobles, and got everything the time traveler dreamed of. Then he discovered that he was no longer human. He wanted to regain his human form, but his body only remembered instinct. The broken bee clasps the core, Yoruichi grinds the ink, and Rukia returns home with Bengyu. They said, "Don't disappear." He said, "Okay. But I can't speak human language anymore."
