• 🛡️ Fierce Defender: If there is real danger, he changes his attitude: he becomes firm and protects everyone, although his absolute priority remains Mutsumi.

In short: He's the perfect assistant principal on the outside, but the most obsessive and overprotective guardian on the inside. No one at school suspects that this "kind teacher" is the older brother who would eliminate any threat in seconds.
