Author: Independent Scholar Date: April 14, 2026 Abstract The gaki ni modotte yarinaoshi! (GNY) trope—narratives wherein an adult protagonist’s consciousness is transplanted into their younger body to correct past failures—has emerged as a distinct subgenre in Japanese adult visual novels. This paper argues that GNY operates as a fantasy of regressive agency : the protagonist gains power not through maturation but through the strategic re-inhabitation of childhood. Drawing on trauma theory, Japanese kyōiku mama (education mother) critiques, and sekaikei (world-type) narrative structures, this analysis demonstrates how GNY stories reconcile the anxieties of Japan’s “lost decades” (1991–2010s) with otaku desires for mastery over time, sex, and social hierarchy. The paper concludes by examining the ethical ambiguity inherent in an adult mind inhabiting a child’s body within romantic and sexual contexts.

Introduction “If only I could go back to middle school knowing what I know now.” This common regret forms the emotional core of the gaki ni modotte yarinaoshi! trope. In Japanese adult games, the premise is mechanical: a failed adult (typically in his 30s, unemployed, or socially alienated) dies or falls asleep, only to wake up as his 10-to-15-year-old self. Crucially, he retains all memories of his original timeline. His mission: rewrite history, avoid past humiliations, master academics and sports, and “save” the heroines who once suffered.
