Madoushi: The Battle of Kiri and Kumo is the eighteenth episode of Final Fantasy: Unlimited.
Oscha, standing in a dark room, holding a small straw doll, speaks to a red cape and sword, similar to Makenshi's. A cloud of red mist appears, and a man similar in appearance to Makenshi, standing in the center of it. Oscar confirms the man's suspicion that he has been revived, calling him Madoushi.
Jane has found its way on top of the clouds, where is seems to rest on them. The children wonder whether the clouds can support them, but hesitate to test. Chobi leaps off before Yu can stop him, and confirms the clouds support people. Most of the crew take the opportunity to relax, after all the hard work they've done recently.
In the bridge, Cid explains to Knave that they can't move and wonders what challenge that this part of the puzzle poses. Lisa feels the energy of the clouds, but cannot sense threat. Kaze stands apart from the others, distracted by something.
At the fortress of Gaudium, Makenshi sits outside on the ledge, also distracted, as Oscha looks on. Inside the Earl informs Pist that Oscha will present the next challenge to the crew of Jane. Returning outside, Makenshi is surprised about something.
The crew returns to the Jane when pillars of stone erupt from the clouds. What emerges looks akin to the ruins of a lost civilization, and standing at the foot is Madoushi. The crew mistakes him for Makenshi in red clothes, and prepares to fire.
Madoushi destroys her with a sweep of his sword. The released a wave of energy seals Kaze in a red cube.
Crux is overhead, moments before Makenshi descends. The two talk with Madoushi claiming he was revived to finish his fight with Makenshi, who he reveals is his brother.
Makenshi and Madoushi's world was destroyed by falling meteorites and one of Makenshi's dragons flying overhead. Madoushi has come to discover which of the two is the stronger, and challenges Makenshi.
After Makenshi refuses to draw his sword, Madoushi charges to force him. Makenshi draws his sword and the two duel. The powers escalate until Pist, observing from his lair, worries the Ocean Puzzle cannot handle this amount of power.
Madoushi defeats Makenshi, but before he had stricken the finishing blow, the gem in his sword shatters. Realizing it was Shiva that shattered it, Madoushi charges Makenshi, who is recovering, to finish the fight. Makenshi overpowers Madoushi and kills him.
With Madoushi dead, the mist dissipates, allowing the crew of Jane to move freely. Kaze has drawn his sidearm, and aimed it at Makenshi. Lisa recalls the destruction they unleashed last time they fought.
Before Kaze can engage Makenshi, Jane and her crew are transported to the next part of the Ocean Puzzle.
