In the underground city of ‘Tentacle City,’ there exists a charismatic Tentacle Master known by the codename ‘Seven’—the only one to hold the highest rank of Level 7. A Tentacle Master is one who commands and manipulates tentacle creatures driven by carnal instinct, using them to train women.
Seven had grown weary of low-level training requests and taken a vacation. Then, one day, a peculiar job offer arrives.
“My daughter Elis possesses an unfortunate constitution—Level 7 tentacle resistance. Therefore, I have no choice but to request your services, Seven. Please transform my daughter into a first-class pleasure slave within one week.”
Elis Sheffield—the sole daughter of the Steel King Sheffield, known throughout the surface world. Even for a charismatic Tentacle Master like Seven, training a woman with Level 7 tentacle resistance is unprecedented. The interest in the Steel King’s daughter and the prospect of obtaining the ideal subject ignites Seven’s passion as a trainer.
The unimaginable tentacle spectacle is about to begin.
As Seven, your objective is to train Elis into a perfect slave within the time limit and fulfill the Steel King Sheffield’s request. Live up to the name of Tentacle Master and transform Elis into the ultimate pleasure slave using tentacles.
Voice acting: Haruno Sakaki
Editorial Review
Tentacle Master ~Seven~ plants itself squarely in the extreme end of the corruption-and-training subgenre, alongside other high-concept fantasy scenarios that use supernatural elements to justify extended sequences of non-consensual sexual content. The tentacle-based premise allows creators to sidestep anatomical limitations while maintaining the fantasy logic that justifies the narrative—a common design choice in this particular niche.
What distinguishes this work is its inverted power dynamic framing. Rather than positioning the protagonist as a victim stumbling into entrapment, the synopsis establishes Elis as someone whose family actively commissions her degradation, and Seven as a specialized service provider operating within an established underground economy. This pseudo-professional framework—complete with resistance “levels” and formal contract terms—gives the corruption narrative a structural skeleton that many similar works lack. The one-week timeline creates explicit pacing pressure, while Elis’s inherited aristocratic status provides thematic contrast to her descent.
The blend of breeding, bondage, and group-sex tags alongside the central tentacle focus suggests comprehensive exploitation rather than a single-axis fixation, indicating broader sexual content variety within the training sequences. The inclusion of a patch notification suggests at least minimal ongoing developer support and refinement.
This work appeals primarily to readers specifically seeking extreme corruption narratives with non-consensual framing, family-commissioned humiliation, and sustained tentacle-focused content. Newcomers to the subgenre or those preferring consensual setup, limited group dynamics, or softer corruption arcs should look elsewhere.
For enthusiasts of systematic, family-enabled sexual degradation with supernatural elements and high-intensity training scenarios, Tentacle Master ~Seven~ delivers concentrated focus on its specific niche without apology or narrative softening.
