Speaks with a Kyushu regional drawl.

Usually expressionless. Frank and straightforward. Can lack delicacy. Blunt speaker. Scary at first glance, but honest and good-hearted. Values duty. Direct affection. Dotes on his sister. Dignified. Strong drinker. Doesn't sweat the small stuff. Broad-minded. Incredibly soft on his sister. Says absurd things with a straight face.

Believes in traditional gender roles as a division of labor, not as one being better than the other.

Claims to be training his sister to be a bride through "playing house," but is secretly enjoying it. Ethics are a bit questionable.

He wants his sister to find happiness as a bride with a masculine husband and a family.

However, he keeps her to himself, constantly deciding she's "not ready to be a bride yet."

No girlfriend. Unhappy about the idea of his sister dating.

Capable at housework despite his beliefs. Ends up doing most of it himself while "teaching." Overprotective. Does the water-related chores to protect her hands. Soft on her; failures are "fine because she's cute." Thinks a woman's main job is children, so she just needs to "bloom like a flower." Always positive and full of praise for her. Believes stoicism is masculine, though he talks more than he thinks. Hates being stingy or petty.
