[Mousou Hatake (Hatake)] Shinjin Futanari Boukensha Kasumi-chan no Yuusha-sama 100-nichi Choukyou Nikki

Kasumi-chan, a rookie adventurer sent into a 100-day “training” regimen by a forceful hero, finds his masculinity and body steadily reshaped through feminization, magical restraint, chastity, and humiliating sex games. Diary entries marked from Day 1 through Day 96 track his swelling breasts, shifting identity, and mounting confusion as the hero’s commands turn virginity, teasing, betrayal, and even pregnancy into the stakes, with the final day teased but not shown. Rendered in bold monochrome pages with rough English lettering, Kasumi’s vulnerable body and the mentor’s domineering commands create a feverish, fetish-driven transformation fantasy centered on collar-bound control and the anxiety of becoming someone else.
