Sengoku Blade: Sengoku Ace Episode II , also known as Tengai, is a horizontally scrolling shoot 'em up video game released for arcade machines in 1996 by Psikyo as a sequel to the 1993 shooter Sengoku Ace.

Sengoku Blade marked a complete breakout of the Sengoku Ace series from the classic Sonic Wings-style system (the first Sengoku Ace was still scrolled vertically), but this time with a much more complex gameplay system in which the player characters fly around on the screen by themselves instead of piloting various aircraft, in a way similar to the 1997 Psikyo game Sol Divide. Episode II was noticeably harder than its predecessor, and featured much better and for its time stunning 2-D graphics, including impressive parallax scrolling effects and detailed and well-animated characters and backgrounds. On the other hand, its music soundtrack appeared to be a step back from the previous game. Just like the previous game, the sequel features multiple endings, different for various characters, as well as branching paths for the different sets of levels.

In December 2004 the game was also ported to PlayStation 2 as part of the Psikyo Shooting Collection Vol. 2: Sengoku Ace & Sengoku Blade by Taito; it also was re-released one year later as a budget-range title. The Japanese release contains both Sengoku Ace and Sengoku Blade, but in Europe the two games were sold separately.
