Oni Onsen

Oni Onsen is a voiced yaoi visual novel for players who want a focused romance with a monster-fantasy edge. It keeps things dramatic but playful, leaning into longing and payoff rather than constant tension.

Story

Samurai Asano lost his home and his onsen when his daimyo master betrayed him during the invasion of his homeland, handing the property to the warlord's daughter, Mina, to fund her father's ambitions. Bent on revenge, Asano sets out to ruin the onsen, only for Mina's arrival to free four oni sealed away in an old sagemono. The oni pledge to protect Mina and stop Asano, but their attention soon turns toward him, since old legend says an oni can only leave the onsen for good if a member of the founding family falls in love with him — a condition the oni intend to fulfill in the most physical way possible.

Gameplay

Play follows Asano's shifting position between revenge and entanglement, with story choices steering how he responds to Mina and to each of the four oni. Dialogue and decisions shape which oni's attention deepens into a full romance, giving the game a branching-route structure typical of dating sims built around a small, fixed cast.

Features

• Four distinct oni love interests, each following his own path toward Asano
• Full voice acting across the cast
• 2D character art built around a folklore-inspired onsen setting
• Male-male romance and adult content throughout, aimed at a yaoi/bara audience
