Editorial Review

★3.8 / 5 — henhenta editorial rating (our own assessment, not the DLsite official user score)

Fan books built around Arknights’ protagonist-as-commander setup are a crowded corner of the R18 doujinshi space, and this one sides with the “Doctor as the object of desire” angle rather than the more common reverse. Its premise is an overworked medic who spends his days on battlefields and bases, and the book treats the late-night barracks as the place where that composure finally gives out.

The most distinctive element is the structure promised by the synopsis. Multiple operators take their turn with the doctor, so this is an ensemble-driven, rotating-partner format rather than a single-pairing romance. That suits a franchise with such a large cast, and it gives readers variety within one volume. The framing of the workplace refusing to stay separate from the bedroom adds a thin but useful narrative hook that fits the source material’s themes of constant duty and fatigue. The grayscale presentation is a deliberate production choice that favors linework and tonal contrast over color polish, as is typical of fan books. The credited guest contributor, mikojin, suggests some collaborative variety, though the listing doesn’t say how much. The official English description and the PDF format make it easy for international readers to pick up. The synopsis is sparse, so expect the appeal to rest on cast chemistry and situation rather than any elaborate plot.

This is best suited to Arknights fans who enjoy male-protagonist-receiving scenarios, group dynamics, and the tired-professional-unwinds trope, and who care more about character interplay than story depth.

Verdict: A focused, fandom-literate ensemble fan book that delivers its premise cleanly, and a safe pick for readers already invested in the cast.
