Jets of flame blast from the Karyuu"Karyuu" literally means "fire dragon".
That's actually not the Kikka but the Ki-201 Karyu, IJA's Me262 copy.
Judging by the tailplane located in the middle of the vertical stabiliser and the vertical stabilizer's shape, I agree with Seiei97. This is the Ki-201 Karyu. The Kikka has the horizontal stabilizer blended off the tailplane root and the vertical stabilizer's rudders are more squared off
