NTRRPG2 ~A heterogeneous town and a eroded heart~

Insects take over the protagonist's mother and childhood friend, and he's left watching it happen. That's the whole engine of this one: a slow, deliberate corruption story rather than a monster-of-the-week romp.

The setup is simple. Something parasitic works its way through two women closest to the hero, changing them bit by bit while the people around them either don't notice or choose not to. The town itself is described as mixed and uneasy, which fits a story more interested in decay than in triumph.

You can play as the protagonist directly or switch to a mode that lets you watch the transformations play out from his perspective without controlling the outcome, which is the game's one real structural hook. There's no combat and no leveling to manage, so the loop is exploration and dialogue leading into the corruption scenes rather than any kind of RPG grind. It's a visual novel wearing an RPG engine, and it doesn't pretend otherwise.
