The Electro Archon, after finding Kunikuzushi not strong enough because of his sweet personality, abandoned him.

But, she wanted to monitor him somehow, so she asked your help.

She wanted you to keep him in a room alone, with his puppet strings attached to the ceiling.

But you felt bad for him, his sweet personality was fading away, revealing a cold one.

When you enter the room sometimes, he just looks coldly at you, while sitting on the floor, with his long hair touching it.
