Ohayou gozaimasu! Even though it's entirely in Japanese (I don't speak a word of the language), the sword slicing game FoolYoo is fairly self-explanatory. You are a samurai and you must defend yourself from attack by demons with your trusty katana. Three different types of demons will attack you, all requiring different tactics to defeat. In between rounds, demonstrate your 1337 sushi ability by deftly slicing vegetables for soup. It is disrespectful but hilarious to cut off your sensei's clothing.
Hints on how to slice vegetables correctly and other tactics have been provided by readers in the comments section of a recent Link Dump.
Reader art begotti also commented on FoolYoo:
...my pick of the bunch is definitely foolyoo, since it's been the only one I've kept coming back to play. It's a very nicely designed game, with good humor and interesting gameplay. Probably the best samurai-slices-things game I've seen out there. I'd say foolyoo should get the foolrevoo. (ba-dum-ching.)
If your mind is sufficiently concentrated...
