Samurai Slice (ゐあひ斬り,Wiahikiri?) is the 8th game in Rhythm Tengoku. In this game, a middle-aged samurai, the Wandering Samurai, is protecting a town from monsters wearing tengu masks to slice them up. Getting a perfect on this game earns a gift called "Asian Drum" that can be found in the studio.
The player uses the A Button to quickly unsheathe, slice, and re-sheathe their sword in order to cut down enemies moving to the beat of the music. Fog eventually creeps in to obscure the player's vision of the enemies and forces them to use their sense of rhythm to best them. The more times the samurai succeeds in felling his enemies, the more intense his stance and hairstyle become.
Hit: The samurai slices the enemy directly in half.
Barely: The samurai's sword smacks the enemy, causing it to tumble off the screen. A barely counts as a miss.
Miss: The enemy counties its path and hits the samurai, making him cry out in pain while flinging his entire body backward.
The name of the game uses an old letter (ゐ) that is rarely used in current Japanese. In modern Japanese, the game's actual name would be いあひ斬り which would mean "killing an opponent by drawing one's sword"
This is one of the few games that doesn't have a practice session in the Rhythm Heaven Series.
Samurai Slice has become rather well-known for being one of the first rhythm games in the franchise. This has allowed it to make it into the next three games, including one endless game in the series, with new mechanics.
