A documentary-style story depicting three girls undergoing enema-based conditioning. This intense work closely follows the psychological transformation of the girls as they move from the collapse of self-identity toward awakening. The raw, realistic portrayal—including the moment of breakdown, expressed in lines like "My asshole is twitching and getting so hot... I can't take it anymore"—heightens the impact of the narrative. Through this process, the girls are transformed into "my own little sister" as desired by the protagonist. A shocking and powerful volume where psychological evolution merges with vivid realism.
