Honoka Tamarai is a student in the same class as Arata Kaizaki.
She has a fairly slim build, her body is very developed and seems to be more built up in comparison to Kairu due to her being a sporty person all in all
She has about chin length brown hair, she also keeps 2 blue pins in her hair, reason unknown
She is a outwardly cheerful person that's very caring. She's also very clumsy. Inwardly she's thoughtful. She deeply cares for her friends, especially Kariu Rena. She's a character that's as readable as an open book. How she feels is clearly shown in the anime.
