Mio Akiyama ( ) is the mature but scaredy-cat bassist, and second vocalist of the band Ho-kago Tea Time.

Her voice providers are Yōko Hikasa (Japanese) and Cristina Valenzuela (English).

CharacterEdit Edit

Mio is the bass player of the Light Music Club. Even though she acts mature, calm and collected most of the time, she freaks out from things she's afraid of, are gross, or pertain to gore. She is atsundere towards Ritsu often, due to Ritsu's immaturity. Because of her extreme shyness, she chose the bass over the more conspicuous guitar. She is so delicate that merely imagining herself being the center of attention almost makes her faint, but she still plays the bass quite well. She is kind and warm with others, caring about her friends and knowing they are important to her.

Although she is not altogether uninterested in joining a band outside school, the time she spends with the Light Music Club members is the time she enjoys the most, so she has completely devoted herself to the club, and during the school festival performance in the fall of her first high school year, she acted as lead vocalist instead of Yui, who had lost her voice. At the time it seemed like Mio might have overcome her stage fright, but after the performance ended, she tripped over a cord and fell, exposing her panties, and was traumatized anew.

AppearanceEdit Edit

Mio stands at 5'3", being the tallest in the group and has straight, long, black hair and gray-blue eyes. As shown in episode 4 of season 1, she is also quite a bit more busty than the others (except Mugi), much to Yui and Ritsu's dismay, and later Azusa's as well.

Attires Edit Edit

Pants over skirts. In summertime, she likes to wear sleeveless clothes, such as tank tops.
