Mikage Sharaku

Mikage Sharaku is the martial arts teacher of Mairu and Kururi alongside her brother Eijirou. The novels frequently describe Mikage as having a very masculine appearance, brought on by years of intense physical training. She has short brown hair and eyes and her usual attire consists of gym shorts, a training top, and a light jacket. Mikage's personality is described as being tomboyish by others which was likely because most of her time is spent around her brothers. She's usually level-headed but can get easily flustered when her inexperience with romance is brought up. As a teacher, she is shown to be very caring towards her students but also strict enough to keep them in line. As seen in volume 9, Mikage also appears to be slightly amoral as she has no qualms about killing but takes issue when Izumii attempts to rape an unconscious Earthworm. Mikage is shown to be in peak physical condition due to her profession as a martial arts instructor. She has enough raw physical strength to damage concrete and her training has disciplined her to be a very focused and deadly fighter. Her fighting style is one that is studied by a famous martial artist, Traugott Geissendorfer, who owns his own global chain of martial arts schools.
