Area Conversation
"I want to try something that the four of us can do together!"
―Tenma Saki

Tenma Saki (天馬咲希) is a first-year student at Miyamasuzaka Girls Academy. She's the keyboardist of Leo/need.

She's childhood friends with her fellow band members.


Saki was born with a weak body. Because of her weak body, she could not attend middle school. Her older brother, Tsukasa, took care of her during that time. However, she became healthy enough to attend high school.

Saki was childhood friends with Hoshino Ichika, Mochizuki Honami and Hinomori Shiho. Due to an incident at the school, their relationship became strained.


Saki has pink eyes and long blonde hair with pink-colored tips. She wears her hair in twin tails.

Her casual outfit consists of a white loose blouse covered with cream pink sweater with pink thin ribbon, light blue denim skirt and black shoes with pink knee-socks.

Her band uniform consists of a white blouse with a red striped tie and a yellow coat, a black cloth bracelet, a black skirt with yellow lining and a black leather belt with yellow lining, black thigh-high socks and black heeled mary-janes with a gold star in the middle.


Saki is a cheerful, bright mood-maker who tries her best to never stops smiling. She is the younger sister of Tsukasa, and seems to take a liking to gyaru styles and subculture.

As a child, Saki would often miss out on large amounts of school due to her sickly condition, at one point becoming homeschooled for a period of time. During her childhood years of isolation, Saki would often experience feelings of loneliness, sometimes entering states where she could not bring herself to smile despite her brother's best efforts. Due to being hospitalized for such a long time, she has become determined to live life to fullest and not miss out on anything. However, due to this desire, she can sometimes ignore her own limits and neglect her health, a habit she is working on getting rid of.

Both Saki and her brother Tsukasa love theme parks and it's attractions. She often drags her bandmates to Phoenix Wonderland, much to their displeasure.

Hoshino Ichika: Childhood friends and bandmates. Ichika feels Saki is always smiling, while Saki is glad Ichika is always there for her. Ichika often worries for Saki's wellbeing, while Saki tries to assure her that she has nothing to worry about. The two have a close and friendly relationship.

Mochizuki Honami: Childhood friends and bandmates. They had lost touch due to Saki's hospitalization, but have since reunited. They have a warm and friendly relationship.

Hinomori Shiho: Childhood friends and bandmates. Their relationship was once strained, but they have since reunited and become closer. Saki can sometimes see Shiho as too serious, but admires her skills as a musician and enjoys being praised by her.

Tenma Tsukasa: Saki's older brother. Tsukasa is shown to have always taken care of her during the times when she was sick. He wanted Saki and her childhood friends together again, since he partly blamed himself for not preventing their friendship becoming strained. Tsukasa is often showing off in front of Saki and the others, which ends in chaos, much to Saki's embarrassment. Despite this, Tsukasa is working hard to protect her friendship so it will not be strained anymore.

Kiritani Haruka: Classmates from 1-C, and friends following the Miyamasuzaka Sports Fes event.

Ootori Emu: Participated in the Sports Fes together. When they first met, Saki had commented on how Emu had reminded her of her brother despite being unaware of Tsukasa and Emu's relationship at the time.

Hanasato Minori: Co-workers at their cafe part-time job.

Aoyagi Touya: He was childhood friends with both the Tenma siblings (Saki and Tsukasa), as their parents knew each other due to the piano. He still worries about Saki's condition, as he asks her about it when Touya, Saki and Tsukasa hang out together after school. (Mentioned in Touya's initial 3 star card.)
