This is such an old thread but I can't be ass'd to start a new one. I kinda stumbled upon it a while ago and was intrigued by the sprites and tried it on an emulator. Slightly disappointed with the gameplay and just wished they pushed the megabits up few as it sits on a 2megabit HuCard.
This is one of those games that require some time in levelling up before charging forward. Thankfully you can side track back and enemies will respawn. The further into the game will allow you to gain the abilities linked to the elements of: Wind. Wood, Fire and Earth.
If only AICOM were more ambitious (and perhaps more experienced with the pc engine) with things like you know... gameplay, graphics etc. This could have been a quality rendition of Streets of Rage set in feudal japan.

I feel the saving grace in this game is the music, It's warm, oriental notes are somewhat comforting to listen too and, a little romantic in some places but as with the case of a lot of game music tracks I feel they loop too quickly.
A kinda decent review of said game:
