What's supernatural and suspicious? A monster, or, if you know the Japanese term, a yokai.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own.
Hey, Mr. Yokai. You asked for me, what's up?
This yokai always wears a short-sleeved T-shirt.
You have a yokai friend? I'm jealous!
