Once the background has reappeared behind Mirai Ninja and the stage's title has appeared on the screen, the unique "boss" theme of Raimei Hoshi will start to be heard from the Yamaha YM-2151, as he materializes in front of Mirai Ninja, then sets up an invisible wall which will not disappear until he has been defeated (much like the original incarnation of Pistol Daimyo did in the eighth and twenty-second stages of Beraboh Man); he will then summon up three turquoise spirits to fly around above Mirai Ninja (which will occasionally swoop down to attack him). Even though Mirai Ninja cannot penetrate that invisible wall, his shurikens can, meaning that the best way to attack him is to crouch down to avoid getting hit by the turquoise spirits as they fly around above you and continuously throw shurikens at him - and once you have thrown enough shurikens at him he will bend over at the waist and those three turquoise spirits will disappear. He'll now attack by shooting turquoise flames directly at you (which you must again crouch down to avoid getting hit by); once you've thrown enough shurikens at him to defeat him, the song you are hearing from the Yamaha YM-2151 will suddenly stop, as he disintegrates and the invisible wall disappears. The hologrammatical image of the Evil Master Shikinami Kurosagi will then appear in the background for a tenth (and final) time, as a remix of Ashura's unique "boss" theme starts to be heard from the Yamaha YM-2151 and he rises up from below for the second time in the game; as with the first time you fought him at the end of the tenth stage, he will attack by slowly walking towards you with the five dreadlocks on his head waving randomly around, meaning that the best way to attack him is to again continuously throw shurikens at him and make his dreadlocks fly off then jump over him to the other side of the room once he gets too close to you. However, once you've thrown enough shurikens at him to make his last dreadlock fly off on this occasion, an electrical force-field will appear around him, which means that the only way you can finish him off is by running up to him, and continuously slashing him with your sword at close range - and because you'll lose 12 (一二)-15 (一五) energy points every time you get hit, you must have at least 70 (七〇) energy points left to do so. Once you have slashed Ashura with your sword at close range enough times to defeat him for a second time, he will explode and the "stage clear" theme will be heard from the Yamaha YM-2151 for a twelfth time as Mirai Ninja runs over to the tree trunk on the left side of the room to free Princess Saki; the pair will then both run off the right side of the screen together, and you can sit back and enjoy the ending, which depicts an enormous cannon shooting a fireball at Kikai Kejō, as it tries to run off into the distance, and a lookout platform (with Mirai Ninja and Princess Saki, the latter of whom is depicted with yellow skin like a Simpson, standing on it) getting thrown from the resulting explosion:
After the credits have finished, the game will go into high-score mode as the high-score theme starts to be heard from the Yamaha YM-2151; your score will most likely be the highest on the cabinet to date, so you should enter your name (of up to sixteen letters) at the top of that table with pride. Once you have done so, the game will go back into attract mode, and replay your performance from the first half of the first stage - and you may wish to watch this to see how well you were doing at the start of the game, before you decide to walk away from the cabinet. The high-score theme will also continue to be heard from the Yamaha YM-2151 in the game after it has gone back into attract mode (until it completes a full attract cycle) which is somewhat unusual.
