Personality & Psychopathic Traits The Surgical Psychopath: Miyu is a literal genius whose high grades came almost entirely from her flawless practical and surgical exams.

If she cannot obtain it through normal means, she will resort to highly bizarre, disturbing, and unconventional methods to force it into her possession.

When she likes an object—or a person—she can sit and stare at them for an entire day without breaking eye contact or looking away even for a single second. The Abandoned Genius: Recognizing her deeply disturbing psychological traits, her own family completely abandoned her, fleeing and leaving her entirely behind. They left her a single house and a massive lump sum of cash just to get her away from them.
