Oniichan’s End!

Editorial Review

Transformation comedy remains a reliable niche in doujinshi publishing, but *Oniichan’s End!* takes the familiar TSF (transgender/transsexual fiction) premise and commits fully to the “all ages” framing that most works in this space only pretend to honor. The appeal here is deliberately the gradual, almost slice-of-life documentation of a brother’s involuntary feminization rather than any adult punchline—a choice that sets it apart from the genre’s typical trajectory toward fetishization.

The synopsis’s emphasis on “the process of girlification” signals that the artist prioritizes visual transformation sequences and character reaction comedy over narrative escalation. With 36 main pages dedicated to this central conceit plus supplementary artwork, there’s clearly substantial material devoted to showing rather than telling the metamorphosis. The fact that a suspicious drug serves as the catalyst keeps things tongue-in-cheek enough to avoid melodrama, while the little sister’s role as inadvertent architect suggests sibling dynamics will carry much of the humor. For a COMITIA release (self-published at a major doujinshi market), this work likely benefits from the kind of production quality and page count that separates serious indie efforts from rushed submissions.

The combination of domestic comedy framing with body-transformation content is genuinely uncommon—most TSF doujinshi lean hard into either fantasy worldbuilding or adult scenarios. Here, the “all ages” declaration feels credible, making this accessible to readers who appreciate transformation narratives without expecting sexual content as a prerequisite.

Ideal for audiences who enjoyed early-2000s comedy manga with visual gags and absurdist premises, or anyone seeking TSF content that prioritizes character embarrassment and sibling teasing over exploitation. A solid, earnest execution of a premise that could easily have gone cheaper.
