The Hylann Defense Corps

The Hylann Defense Corps is a 3DCG adventure for players who want monster girl encounters wrapped around a military training premise. The tone leans serious about its world while staying focused on adult content.

Story

A century after The Grieving nearly wiped out men, elves, and orcs and pushed humanity into isolation, peace has held along the Hylann Dynasty's shores. Ashton, a recruit finishing his training with the 107th Trainee Unit, is set to join the Hylann Defense Corps, the diminished but still-standing military force descended from that war. As his unit nears graduation, early signs suggest the quiet the Dynasty has enjoyed may not last.

Gameplay

Players follow Ashton through his final stretch of HDC training, moving between story scenes rendered in 3DCG as he and his unit prepare for active duty. The game centers on encounters with monster girls, framed through an internal-view perspective and female-domination dynamics, with animated scenes marking key moments rather than a separate combat or management layer.

Features

• 3DCG art with animated scenes for key encounters
• Monster girl encounters built around female domination and internal-view perspectives
• A male protagonist story set against a post-war military backdrop
