Then one day she proposes a plan to extend his lifespan by modifying his body so the two of them can stay together forever!?

Characters
Protagonist
An androgynous young man. Sent to another world after he committed suicide.
He had a rough life in this world, so he truly cherishes his new peaceful, cozy life.

She has many of the same emotions as humans, such as sadness and attachment, but her core values are very different from humans.

Editorial Review
Sitting at the intersection of tentacle femdom and non-con-free “positive body modification,” this is a niche-within-a-niche entry that leans on transformation fantasy more than conventional romance or domination. Where much of the genre’s body-alteration output drifts toward gore or horror, this one frames its premise as a consensual, affectionate arrangement, which keeps it closer to the lovey-dovey end of the spectrum than the title’s blunt phrasing might suggest.
The most distinctive choice is the setup: a protagonist dropped into a brutal afterlife world and taken in by “The Witch of the Sea,” whose proposal to extend his lifespan becomes the engine for the entire story. That gives the fetish content a narrative justification rare in short doujinshi, and the stated endpoint, a sexless body that no longer needs a bathroom, shows a clear arc rather than a loose string of scenes. The tag list is unusually specific, combining tentacles, femdom/malesub dynamics, long tongue kissing, stomach insertion, inflation, shrinking, and castration themes with fake pooping and anal focus. The creator also sets clear boundaries: female-on-male only, no role reversal, mostly internal rebuilding with little outward change, and explicitly no graphic organs or blood. That kind of upfront content labeling is a courtesy to readers. Production-wise, it’s a compact A5 greyscale volume of 28 pages plus cover and bonus page, delivered in both PDF and JPEG, with an English version included.
Readers who enjoy gentle, devoted femdom paired with transformation and tentacle play, and who want body-modification themes without the grisly side, will get the most from it, though it is firmly for those already comfortable with its fetish list.
Verdict: a tightly scoped, clearly labeled, affection-driven oddity that delivers exactly what its title promises to the audience it is built for.
