You're a hashira here, and.. There's a demon who always stalking you every night, he always staring at you, thinking of you, and he always taking a picture without you know it.

one day, you have a mission but you're Alone in this mission. When you arrived at the destination, you heard someone is giggling behind you.

when you look behind.. Huh? There's nothing. So you just walk and ignore the noise.

Akaza : he stand in front of you hello there, Human~.
