A first year student at Seijou Academy.

A delicate girl who is the manager of the kendo team.

Though she doesn't have any particular illness, she has much less stamina than normal people so it's hard for her to do any strenuous exercise.
On the other hand, she's extremely determined and diligent about her job as a manager and helps contribute to the team's success.

Her hobbies are reading and cooking.

Though she'll randomly read all genres, after becoming manager, she's increased the type of material that pertains to kendo such as "Continuing Kendo! ~From cradle to grave~" and "Snacks for each of the Three Meals a Day for a Sports Player".

Role: Underling Oni Slayer
A young girl who is staying over at Shoushinji, the same location as the training camp.

She arrived there earlier than Shouko and the others.
She's fundamentally a genius.

Looking at her, there's not doubt that she's stylish either.

If she just kept quiet, she'd already be a rather beautiful girl, so along with her outstanding athletic ability, she has rather high specs and is a praiseworthy person.

She's got a light carefree personality.

Perhaps it's because she was raised in the South, but she's seems rather loose with deadlines.

However, her movement pattern regarding the tides indicates that might not be the case?

The young girl who washed up on the shores near the location of the training camp. Main heroine of the story.

Looks to be about 10 to 12 years old.

Her name and age are all unknown.

The first impression of her is that of a mermaid or a doll.

She doesn't seem to know who she herself is either.

The first ones she saw when she woke up were Shouko and Yasumi, so it seems she became attached to them, much like a chick imprinting.

Her normal mode is to be spaced out.

Voiced byOokubo Aiko


Seijou Girls Academy first year student. Belongs to the kendo team.
Though she only started kendo in high school and has only been learning for not even half a year, because of her high, natural athletic ability, strong determination, and the will the win, those three pillars of strength have her pegged as the next ace.
She has many varied, passing interests in a variety of things but is a bit bothersome about a certain genre of music.
When she entered high school, it was vital for her to join the light music (rock) club, but since it didn't exist, she abandoned the idea and followed Yasumi into joining the kendo team.
She's a dorm student and is Yasumi's roommate. She also has a unrequited crush on Yasumi.

The advisor to the Seijou Girl's Academy kendo team.

A new teacher who became the advisor to the kendo team after the previous advisor retired.

She's really fired up about her work since she considers her profession her calling, and wants to be seen as dependable by the students.

The truth is, she's completely hopeless at kendo, likes drinking sake, has a complex about her name, wears glasses, and since she's had more life experiences than the students, it seems she's been through a lot.
[From Solelo website]

She is friends with the reporter Sakuya.

Voiced byYoshinari Yuki


A 2nd year student at Seijou Girls Academy. Belongs to the Kendo Team. Just like her appearance, she is a gentle ojou-sama type.

As the Vice-Captain, in combination with her classmate Shouko, the two function as a "Sweet and Whip" (carrot and stick) policy.

Her abilities are rather good, but because she is weak-willed, she's the type that can never give her all in matches. On the other hand, her form is extremely pretty.

Her parents (especially her father) are really overprotective, so she was the person who had the hardest time getting approval for this time's summer training camp, and has an obligation to call home in the mornings and evenings.

Engages inCooking, Kendo
Voiced byAkimoto Yousuke


The Chief Priest of Shoushinji.

Both his voice and height are large, and he is the hearty type.
Since he drinks alcohol, he's somewhat of a corrupt monk. His splendid physical build-up is suitable for being a fighting monk. When he was young, he made quite a sensation in the kendo world. He uses an old-school style of sword-fighting.

Since he and Aoi Hanako's father were both old war-horses and comrades in arms, that connection between them is what led to Shoushinji being picked as the location for the training camp.

Because the temple is poor and has few parishioners, he wouldn't be able to earn enough to eat if that were his full-time job, so he also has a side-job.

Role: Reportage writer and photographer
A beautiful woman of unknown age who appears to be in her mid-twenties, with a distinctly non-Japanese style of living. As Kei's late mother's best friend, for whatever reason, she has taken it upon herself to look after Kei's well-being. She is frank and humorous, with the composure of an elder sister, but also has an "old-timer" side to her befitting (?) of her age. She likes alcoholic beverages and salty things. She dislikes Uzuki.
