Mirai Ninja/Stage 6

Once the background has reappeared behind Mirai Ninja, the stage's title has appeared on the screen, and the stage's theme starts to be heard from the Yamaha YM-2151, start running to the right as you pass a "Shurazo" (written in Kanji as 修羅像) statue in the background which is spitting medium-sized fireballs from its mouth at you, and three Gold Mukademaru materialize in front of you and spit Kanji characters from their mouths; once you have thrown enough shurikens at each of these to kill them, drop down off the edge of the platform, but watch out for ten indestructible Ya Hassha-ho mounted on the walls as you are descending. Once you have landed, you can either: drop down a gap in the platform, or jump over it in order to land on another platform that has two Tourou hovering in place above it - and they will both fire a laser down at you, if you try to pass under them, so you will have to jump up and slash them with your sword at close range to kill them before running back to the left and and dropping down that aforementioned gap in the platform. As you are descending, five Karasu Tengu will come flying towards you; once you've thrown a shuriken at each of these to kill them, and landed, you'll have to jump up to collect an Inori (gray) powerup above you (in order to shrink four more Karasu Tengu that are flying towards you). Once you have thrown a shuriken at each of them to kill them, you can either drop down another gap in the platform, or jump over it in order to collect a Chikara (yellow) powerup if you need the extra energy before running back to the left and dropping down the aforementioned gap in the platform - and once you have landed, four Kumo Robots will come scuttling towards you while firing lasers at you. Once you've thrown a shuriken at each of them to kill them, you will have to drop down into a pit with eight Namekuji in it; you can either throw a shuriken at each of them, or jump up to collect an Kudaki (orange) powerup above you to kill them. You will now have to jump onto the first step of a staircase before jumping up to the second step of the staircase, then jump up to the third step of the staircase before coming to the fourth step of the staircase - and four more Kumo Robots will now come scuttling towards you, while firing lasers at you. Once you've thrown a shuriken at each of them to kill them, you'll have to jump up to the fourth step of the staircase; but when you come to the fifth step of the staircase, you will notice that it has an eleventh Ya Hassha-Ho mounted on the left side, so you will have to be careful as you are jumping up to it. Once you have come to the sixth step of this staircase, you will again notice that it has a twelfth Ya Hassha-ho mounted on the left side, so you will again have to be careful, as you are jumping up to it - and once you reach the seventh step of this staircase, four more Kumo Robots will come scuttling towards while firing lasers at you. Once you have thrown a shuriken at each of them to kill them, you will notice that the aforementioned seventh step of the staircase has a thirteenth Ya Hassha-Ho mounted on the left side, so you will once again have to be careful, as you are jumping up to it; three more Mukademaru (two Gold and and one Silver) will then materialize above you, and start spitting Kanji characters from their mouths, so you'll have to jump up to collect a second Inori (gray) powerup above you in order to shrink them. Once you've jumped up and thrown enough shurikens at each of them to kill them you'll have to jump up to the eighth step of the staircase (which has a shrunken fourteenth Hassha-ho mounted on its left side) before jumping up to the ninth step of the staircase (which, like that previous one, has a shrunken fifteenth Ya Hassha-ho mounted on its left side) - and two Shura will then materialize on either side of you. The one on the right will throw a small fireball into the air in the hope that it will land on you, while the one on the left will throw another small fireball directly at you; once you have thrown enough shurikens at both of these to kill them, you will have to drop down off the edge of the platform as you come to a Zaku who's swinging his mace around in front of you. Once you have thrown enough shurikens at him to kill him, you will have to run past another Shurazo statue in the background, which is firing lasers from its eyes at you - and this stage has no boss, so the hologrammatical image of the Evil Master Shikinami Kurosagi will not appear, and the "stage clear" theme will immediately be heard from the Yamaha YM-2151 at this moment in time as Mirai Ninja proceeds onward to the seventh stage (which, like the first, third and fifth ones, is very straightforward).
