Onahole Training Records: Gold and Silver Furnace

Editorial Review

★3.2 / 5 — henhenta editorial rating (our own assessment, not the DLsite official user score)

Onahole Training Records positions itself within the hardcore ryona-focused corner of adult manga, where narrative serves primarily as scaffolding for extreme body modification and degradation scenarios. This is unambiguous territory: war-defeated elf princesses subjected to amputation, gang assault, and systematic dehumanization in a military dungeon setting. The work makes no pretense toward romance or nuanced characterization.

What distinguishes this doujinshi is its commitment to visual extremity without crossing into gore aesthetics. The creator deliberately excludes blood depiction despite the graphic nature of limb removal and violation—a choice that shifts the work’s psychological weight. It’s degradation-focused rather than splatter-focused, which appeals to a specific subset of the ryona audience: those invested in the humiliation mechanics and helplessness fantasy rather than injury trauma itself. The full-color presentation across 28 pages (24 story plus supplementary materials) indicates production investment, and the inclusion of a text-free version acknowledges the international audience suggested by the trilingual support (Japanese, Simplified Chinese, English).

The premise—half-sisters as dual protagonists—creates a comparative suffering dynamic, a common narrative framing in this subgenre that amplifies isolation and powerlessness through witnessing. For a work this explicitly positioned, the tag combination (四肢○断, 輪○, ryona elements without graphic gore) is relatively niche even within extreme adult manga spaces.

This is strictly for experienced consumers of hardcore degradation content with specific interests in immobility, captivity, and non-consensual objectification scenarios. Casual adult manga readers or those with standard BDSM interests will find this prohibitively harsh. Readers who’ve specifically sought ryona-heavy content and wanted less graphic injury emphasis will find the bloodless-but-brutal approach here deliberately calibrated to their taste.

A methodical, unapologetic entry in the extreme subjugation category—technically competent, thematically committed, and precisely targeted.
