About the Motto! Haramase! Honoo no Oppai Isekai Oppai Bunny Gakuen! English patch

The protagonist heads his school's App Development Club, which on paper is a wholesome activity and in practice is secretly making an adult game set in a bunny-girl academy. While debugging it during a parents' day event, he is pulled into the very world he was building. The academy there, where everyone is a bunny girl, is close to shutting down, and it has summoned him as a legendary teacher to save it.

Motto! Haramase! Oppai Bunny Gakuen! is a fully voiced KiriKiri adventure game by milkfactory (みるくふぁくとりー), released in 2025. It is a long isekai nukige with a large cast of students and their mothers, a nameable protagonist and character profiles, rated at about 43 hours on VNDB.

The English patch translates 43,043 lines of dialogue, narration and choices and redraws 315 interface images, from menus and settings to episode titles and profile cards. It also covers the official Append Disc (+A1) and the 1.02 update. It installs as a launcher that loads the translation alongside the game, leaving the original archives untouched.

Troubleshooting

The game is still in Japanese

You started hbunny.exe. Start hbunny_EN.exe instead, and check that hbunny_EN.exe, KrkrPatch.dll, KrkrPatch.json and the htpatch_en folder are all next to hbunny.exe with their original names.

Some text inside pictures is still in Japanese

A few decorative images such as CG captions and art are left as they are.

Antivirus warns about hbunny_EN.exe

The launcher starts the game with a small helper DLL, which some antivirus programs flag. Allow it or add an exception for the game folder.

Uninstall: Delete hbunny_EN.exe, KrkrPatch.dll, KrkrPatch.json and the htpatch_en folder, then start hbunny.exe as before.

FAQ

Is the Append Disc translated?

Yes. The patch covers the Append (+A1) and the 1.02 update, and the same files work with or without them.

Do I have to reinstall if I add the Append later?

No. Install the Append whenever you like, before or after the patch.

Why is the game still Japanese?

Make sure you launch hbunny_EN.exe; hbunny.exe runs the original game.

Do existing saves work?

Yes. A protagonist name you already entered stays as it is.
