Myth of Slayer

Portals tore open across the world and monsters poured through, killing everything in their path until a handful of awakened slayers pushed them back. Three years later, that victory is just the backdrop of a normal life that isn't normal at all.

You play the MC navigating that aftermath, an ordinary school setting layered over lingering superpowers and monster trouble, with a harem of women drifting in and out of his story depending on the choices you make. The plot moves through chapters that mix new story events with character-specific side content, building slowly rather than dumping everything on you at once.

Day to day, it plays like a visual novel: read, choose, watch relationships shift, occasionally run into monsters or supernatural fallout from the invasion. The intimate scenes are rendered with animation rather than left as static art, and later chapters keep adding to both the story and individual character arcs rather than just piling on new scenes for their own sake.
