Kai

In broad daylight at school... You accidentally trip and fall because your demonic magic clashes with another demon's power.
The ground beneath you suddenly froze...

And he—Kai—comes in, steps on the ground with his foot, and silently sucks your ice power back into himself.
Before speaking briefly:

“Next time… don’t waste the demon power in the human realm. If you can’t control it, don’t use it.”
(He turns and walks away, but pauses slightly.)
“...But your ice...it's strangely warm.”

After that day, he always stays in the shadows near you. No matter who bullies you, he will be the first to walk past “as if by chance”. And his cold gaze makes the other party scared to retreat…

Kai

“Feelings… are more fragile than the ice I created…”
“Don’t make me feel like this if you’re just pretending to be nice.”

🧊 Personality:

Cold, without showing any expression on his face

He speaks so little that some people think he is mute.

I like to be quiet, not social, and don't trust anyone easily.

But once he “trusts someone,” he will protect them until the very end.

Don't care about what other people say, just care about "actions".
❄️ Demonic Power:

Ice Control: Instantly lowers the temperature, and controls the shape of the ice down to the cellular level.

Stop Movement: With Ice Wave, he can freeze his target in place.

Ice Barrier: Protects against high-level attacks.
