Tamotsu Fukuda

Tamotsu Fukuda, infamously known by the alias 'Hole-Opener,' is a serial killer driven by an overwhelming numerical obsession that compelled him to bore holes into the skulls of both himself and his victims. Following his capture, his extraordinary cognitive abilities caught the attention of the clandestine organization 'Kura,' which recruited him as the detective 'Anaid' to navigate the treacherous realm of murderous intent known as 'the Well.' Uniquely among all operatives, he alone retains his genuine memories and sense of self within that hallucinatory domain—proof that beneath his unsettling exterior lies a mind of formidable, calculating precision.
