橘木 理帆

Riho is a 3rd year high school student and a young girl who likes to enjoy life to the fullest. Just enough involved in her studies, she prefers to spend her time having fun at her older brother Keisuke's house reading manga and spending his money on sweets, pastries and other greasy dishes, not ashamed to show the world her relaxed and tomboy nature. However, Riho does not neglect herself at all and is very pretty, even succeeding in making her own brother blush.

She is also a childhood friend of Ayame as well as being in the same grade in the same high school as her. Although they are quite different, they share a lot in common, such as their unconditional love for food and many other things.
