A reverse-engineering and asset preview tool for games built on Koei Tecmo's Katana Engine.
Currently tested against Dead or Alive 6 Last Round. Raw asset export is supported; more features are in active development.

Looking for a Mod Manager for Katana Engine games? → Kashira Mod Manager
- Steam auto-detection — detects supported Katana Engine games from your Steam library automatically
- Mod-safe loading — always reads original game files regardless of installed mods; fully compatible with Kashira Mod Manager
- Asset preview — resolves G1T/G1M texture and model references and renders them inline
- Bundle export — extracts all related assets for a given model in one click (work in progress)
- Windows 10 / 11 (x64)
- .NET 8 Desktop Runtime or later (.NET 9 / 10 are also supported)
- Mesh export (OBJ / glTF) is not yet implemented — only raw asset extraction is currently supported
- Bundle export is functional but incomplete for some asset types
Kissaki is developed strictly for modding and personal research purposes.
You are solely responsible for any use of extracted assets. Redistribution of game assets is strictly prohibited.
