Ginjiro manages to wound the blue "sky beast" with his strange unlocking powers, but the beast manages to escape. Elsewhere, Sekichi is trying to mix some propellant for the firework in time for the festival. Sora slips some odd accelerant into the mixture and seems to get the right reaction.
The day of the festival arrives and Sekichi prepares to light his giant firework consisting of a small old shrine and a lot of gunpowder. However, he is shocked to find Sora sneaking in there and Ginjiro also hops in to pull them both out. Unfortunately, Sora reveals that the three of them have been sealed inside. Ginjiro uses his powers to unlock the shrine and escapes with everyone before the firework shoots up and explodes.
