Sakuya Ohtori

Sakuya is a laid-back third-year at Kotarou's school, playing the protective guardian role for Chihaya, although they’re not actually related. He’s typically a friendly guy, but when it comes to Kotarou, he can't resist teasing him—it’s just too easy. There’s a twist to his story; he was once the Rewriter who gained immortality to protect Minata, but that turned him into a tree! It wasn’t until young Chihaya showed up and knelt before him that he transformed back, finally feeling ready to atone for his past. With a reputation as Gaia's fiercest familiar, he once sliced through Tenma’s Krivoy Rog in one go!
