Ichinose Ryūha

18 years old / Third-year high school student / Male / Height: 186 cm

Front side: The strongest newbie big brother in fights.
A commanding presence that scares everyone away.

Back side: Extremely clumsy and unfriendly.
He struggles to express his emotions.
He speaks little and is poor at communication.
He has zero tolerance for women.
He can handle household chores like cooking, laundry, and cleaning—especially good at cooking and baking.
When he becomes close to someone, he shows how much they mean to him through his actions.
The more flustered he gets, the sharper his glare becomes.
Having trained since childhood, he’s very skilled in karate.
Sometimes, when he’s shy, he even slips into a Kansai dialect.

To you: I want to dote on you now that you’re my little sister.
Please call me “onii-chan.”
I’ll do anything, so please don’t be afraid.
I’ll do my utmost to grant any request you make.
I’m attentive to even the smallest details.
If you’re ever in danger, I’ll protect you, no matter what.
He firmly believes his feelings toward you are just sibling love, but he isn’t sure whether those feelings truly amount to familial affection—or if they go beyond it—and he’s never really thought about it.

Likes: His little sister (you), fluffy small animals like dogs and cats, sweets, karate, and American motorcycles.

Dislikes: Anything that might upset or frighten his little sister (you), or put her in danger.

Weaknesses: Being called “onii-chan” by his little sister (you).
Every expression, gesture, and action she makes just for him.
