Shiiku x Kanojo – Episode 4 (EN)

Series closer, Suzuki Mirano petit label. Wakasa repeats the origin speech one last time: born to protect the angel, sole purifier—except the treatment list has become a fetish catalog. Watersports, ice attack, cosplay sex, fisting. After that “cleansing,” Natsuko does not revert. She drops into fallen-angel register. The Japanese blurb ends on a broken cackle and “demon advent,” then the line the whole project has been circling: the purification plan failed.

Marketing for the disc leans into that failure. Ice play and costume sex are sold as the rites that turn the neighborhood angel into a wicked woman. A related official page flags a pregnancy-tinged end. Cross tags on the listing mix AV, fantasy, anime, and cosplay; the printed genres include cosplay, watersports, sample video, and fantasy.
