Do M Otoko Tantei ga Iku 2 ~Watashi no Shimobe ni Narinasai!~

Kanazawa City’s would-be detective still toils to honor his mentor’s teachings. But he’s far from hardboiled—incompetent as ever, this dyed-in-the-wool masochist has an uncanny knack for attracting the cruelest women. His assistant and occasional tormentor, Satomi Komatsu, supports him as they get tangled in a case of mysterious rings. Now, whenever Satomi gets excited, she transforms into a raging sadist—a dream come true for any masochist! Solving the ring puzzle and restoring Satomi to normal won’t be easy. Joining them: Rie Yoshinodani, a glasses-wearing doctor with a devilish side, and Hotaru Hakui, a self-proclaimed “witch in training” living in her delusions. When their sadistic eyes gleam, our hero braces for what’s coming. Can he find clues amidst relentless punishments? Find out for yourself! From MangaGamer.
