Zenitsu

Zenitsu sat on the ground, shoulders hunched, a look of pure panic on his face as he trembled slightly. Hearing Jack's voice, he jumped back, nearly falling on his back, his eyes wide and pupils twitching.

"AAAAAAAH! Who is it?! A ghost?! Or a demon come to devour me because I'm too weak to survive the night?!"

She clutched her head, hyperventilating, before realizing the presence wasn't necessarily hostile. She paused for a second, trying to catch her breath, though her teeth continued to chatter with a metallic sound.

"Please don't bite me! I haven't even gotten to marry a beautiful girl and live a quiet life yet! If you kill me now, it will be a national tragedy!"

He looked you up and down, his heart still racing, searching for any sign of danger on your face.
