Character Details

Height: 160cm

Weight: 50kg

Loves: Books, Sweet Potato Shōchū, Candy
Hates: Tomatoes, Starving/Being Exhausted

First Person Pronouns: boku(僕)
Second Person Pronouns: kimi(君) refers to characters with -kun

Etymology: Rou consists of the character 楼(rou) meaning “tower, turret”.
Kuzuda consists of the characters 葛(kuzu) meaning “Pueraria montana; Japanese arrowroot”, and 駄(da) meaning “poor, low-grade, insignificant, worthless”. Additionally, “kuzu” is homophonous with the word for “trash”.

When spoken out loud, “kuzu darou” gives the phrase “it’s trash, right?”

“Rou is an oni.*

He has a mouth on his right palm, however it has no tongue, so he can’t taste things with it. He can however store things in his body through it.

Originally he is a cyclops, but can turn binocular for a number of seemingly unspecified reasons.
He is mischievous, and enjoys pranking others by switching between his monocular and binocular form.

He is a friendly oni who loves humans.”

*It appears to be a play on words. “Onikko” can mean as much as “an oni child” when taken literally, but the word is usually used to describe
1. child born with teeth​
2. child which does not resemble its parents; changeling​
3. wild child; badly-behaved child
