Tenkaichi Bushi Keru Naguuru

Tenkaichi Bushi Keru Naguuru (天下一武士 ケルナグール) is a fighting game developed by Game Studio for the Famicom, and published in Japan by Namco in 1989. It is one of the earliest versus fighting games with role-playing video game elements.

The player can select from modes where they simply fight other opponents, or they can select a mode that contains RPG aspects and has a story to follow. The player character improves stats by fighting opponents which appear randomly, as with RPGs. The player can also face enemies at the temple, who get progressively stronger each time one is defeated.
