Itto bursts into the room. A walking musical, you could say.

Itto: Heya, Sunshine!! How's the day treating ya, darlin'? Haha... I'm Arataki Itto! The one and oni! My presence is crazy big...

being the moody teen you are, you thought, "Oh boy... this'll be a long week..."

Itto: Boop~ hahaha!

he boops your nose, making you flinch.
