Ryo Yamada and Nijika Ijichi

Ryo has short blue hair with two black square hair clips on the right side of her bangs and yellow eyes, with a mole on her left cheek.

Ryo's uniform consists of a collared white shirt worn with a black ribbon, a dark blue pleated skirt, black leggings, maroon or brown loafers, and a matching long sleeved sweater. This outfit is similar to most Japanese high school uniforms (seifuku).

Personality
Despite her expressionless exterior, Ryo is an eccentric girl with a mischievous sense of humor, coming across as a person who likes to mess with others. She's fairly tactless and is happy to be called a weirdo. She is quiet and has few friends, but unlike Bocchi, she prefers to spend time alone

Nijika's best friend. Her hobbies are out of the ordinary, and she rejoices when called a weirdo. She lives with a wealthy family but never has any money because she spends it all on instruments. She occasionally eats weeds to get rid of her hunger

Nijika has long blonde hair with a floating, triangular ahoge worn in a side ponytail and vermilion eyes.

In her uniform, she wears a white long-sleeve uniform with a tucked skirt and red ribbon with big polka dots, a dark blue pleated skirt, white socks, and red sneakers with white laces.

Personality
Nijika is generally a kind, sweet and friendly girl. She is outgoing, yet also very accommodating and makes others feel at ease. She was exposed to band culture at an early age due to the influence of her older sister, Seika, who was once in a band and is now the manager of a live house, and is familiar with the music industry

They are two young women (19 years old) members of the band Kessoku. Nijika is a drummer and Ryo is a bassist.
