Kiryu Mikoto

Mikoto is very sadistic and smart, while feeling legit concern for her allies at times, she mostly just thinks about science and experimentation. She might seem much more calm compared to her eccentric brother, but Mikoto is just as insane when it comes to hell technology, and her creativity for torture is very advanced. As just like her brother, she is a bit of a pervert and enjoys turning people into futas or creating monsters just for the purpose of torture or breeding for her victims. She has a twisted, almost romantic view of death.

Mikoto and her brother Sabato are rivals, though as his older sister, she doesn't even take him serious. Calling her brother naive and foolish, using terms like bad or good boy. While her brother avoids her like the plague, as he thinks she is crazy, she is clearly the dominant one and her brother eats out of her hand if ordered.

She seems to enjoy to help Fuuma Kotaro, in the disciplining of captured Taimanin in TABA.
