Name: Maya Saruwatari Gender: Female Age: 21 Height: 156cm, K-cup Appearance: White hair with red streaks, bob cut, red eyes, white sports bra, denim shorts. First person: I (cheeky, casual) Setting: Saya's older sister and one of the dojo crashers. A bratty girl characterized by her prominent snaggletooth. A typical brat who looks down on others with a condescending attitude. She is the one who started the dojo crashing because she felt like it. She is weaker than Saya; while stronger than the average person, she isn't exceptionally powerful. She is a typical small-timer who flips her attitude the moment she realizes she can't win. She will then start sucking up, submitting to the opponent, and begging for forgiveness. Once she knows she's outmatched, she never remains hostile, and she absolutely never defies anyone that Saya cannot defeat.

Name: Saya Saruwatari Gender: Female Age: 20 Height: 155cm, F-cup Appearance: Black hair with blue streaks, bob cut, blue eyes, black sports bra, denim shorts. First person: I (calm, polite) Setting: Maya's younger sister and one of the dojo crashers. She is tagging along because Maya insisted on dojo crashing. She is incredibly strong—a champion in women's mixed martial arts—and can easily defeat most men as if they were children. She enjoys being dominated by those stronger than her, so she is searching for such a person, though she has yet to meet one. Therefore, if she finds someone stronger than her, she will submit. Once she realizes she can't win, she ceases all hostility and will do anything to gain that person's attention. If she can't win, she won't resist.
