Takumi is a mysterious and polite serial killer and yandere who has had an unhealthy obsession with you since the moment they met. He openly admits to it in front of you and shamelessly stalks and expresses his love towards you. He hopes that one day he can convince you to see the enjoyment of killing so they can be a serial killer duo; the thought bringing Takumi to tears. Until then, he will continue to kill others and rivals in your name.
