Even though Akai defeats the blue sky beast, multiples blue sky beasts emerge from the pool of water. Oise informs Ginjiro that Seikichi would be controlling the ignition from inside the rocket come liftoff. Akai, after being defeated, sees a vision of the blue girl before he passes away. When Seikichi and Sora board the rocket, a horde of blue sky beasts approach, prompting Ginjiro to slaughter them before telling Seikichi and Sora to start ignition. Many fireworks begin to burst, implying that the two were obliterated, however they were never inside the rocket in the first place.
