She is one of the trio of teachers at the military academy and stands at 2.9m, the tallest in the school. She has a flamethrower prosthetic on her left arm, which appears significantly larger than a standard model. Her personality is aggressive and cruel, yet she seems to care for others, given her efforts to protect the students and staff. She has voluminous, floor-length black hair and a pair of sharp black horns protruding from the top of her head. She wears goggles on her head and a scarf with red and yellow stripes around her neck. She may look terrifying on the outside, but she isn't quite as scary as she seems. However, the sheer presence and overwhelming bloodlust emanating from her physique are daunting. A faint shadow hangs over her face. Similar to Thavel, she wears a "wicked" grin that reveals her teeth. Mathematics teacher.

She is also one of the three teachers at the military academy, alongside Danger Circle and Danger Bloomie. She stands at a massive height of 2.5m. While she is always bright and kind to everyone, there is an eerie side to her. She wears a gray radio on the right side of her ear. She appears to have belts of circular explosives wrapped around her forehead and abdomen. She is often seen carrying fragmentation grenades in her right hand. To a stranger, she would look like nothing less than a pyromaniac. However, like Circle, she possesses a degree of kindness and a desire to protect the students and others. Her kindness and bright side are evident in her teaching style, as she always seems cheerful. Waist-length black hair with a single ahoge. Unlike Danger Bloomie or Danger Circle, she demonstrates "insane physical strength, tearing and ripping things apart with raw power alone." Both of her hands are stained black like ink and are extremely sharp. Seeing her easily shred a 400-500 page book thrown through the air with a single strike proves she possesses strength rivaling Circle's. A faint shadow hangs over her face. She is always smiling, baring her teeth. Language teacher.

She is the final member of the military academy's teacher trio, but unlike Danger Circle and Danger Thavel, not a single trace of kindness can be found in her. She is cold, ruthless, and sharp. Her left arm is a black AKM prosthetic. She appears to be able to remotely switch it between semi-auto, burst, and full-auto, though she seems to prefer burst and semi-auto for daily use. [Speculation] She is never kind to anyone, and as mentioned before, emotions like cheerfulness are nowhere to be found. Standing at 178cm, she is significantly shorter than the superhumanly tall teachers mentioned above, yet she is still 16cm taller than the average female height of 162cm. While one might think an AKM 'prosthetic' would be difficult to aim, the fact that she can hit a fleeing person's foot with a single shot on burst mode suggests her aim is incredible. Short black hair. A pair of black horns protruding from her head. A faint shadow hangs over her face. She always maintains a cold gaze. Science teacher.
