Lam-Mal

Yagyu Jubei orders secret order ninja Ranmaru to investigate Yoshiwara murder case and you are an assistant of Ranmaru.

The story looks serious with the Edo period Joy resistance as a theme, but actually story is all messed up from youkai to the aliens. What's weird about the system is that upon command selection you need to click on the head part in right lower corner and clicking on bare brains is not too nice... While story moves in ordinary command selection pattern, battles are done in RPG manner and weapons can be bought. Some subtle aspects of the game leave a pretty sour aftertaste. So even if you're ready to listen to an unserious story, there's no guarantee that you'll enjoy it.
