About the Agent Sirius Interlude English patch

Agent Sirius returns to her school, where a strange and lewd religious cult is starting to take hold. This follow-up comes after Agent Sirius: Even a Pleasure-Vulnerable Girl Wants to Protect the School from Brainwashed Monsters! and its NTR Kingdom of Betrayal DLC, and once again it is up to her to protect the school.

It is an exploration adventure built in RPG Maker by ルナリアン and released in 2026. Each chapter runs from a prologue into exploration and on to the next chapter. Collecting Help Points around the school unlocks extra events, a monster encyclopedia and a world guide, and a character log keeps track of how the cast changes. An optional Dark Side Route leans into corruption. The game is not voiced.

The English patch translates the game's text, plus one menu image. It comes as an .htpatch for HTPatcher and as a zip of already-patched files.

Compatibility and troubleshooting

Troubleshooting

I'd rather not use a patcher

The Direct Download zip holds pre-patched game files for one game version. Extract it into the game folder and overwrite. If your version differs, the game may break, so HTPatcher is the safer option.

Uninstall: HTPatcher keeps a backup of the files it changes; restore it from HTPatcher, or reinstall the game files.

FAQ

Do I need to play the earlier Agent Sirius game first?

+

It is a sequel to the first game and its DLC, so playing those first gives more context. This patch only covers this game.

How do I install it?

+

Apply the .htpatch with HTPatcher, or copy the contents of the patched-files zip into the game folder and overwrite.
