Neo Armstrong Cyclone Jet Armstrong Cannon

The Neo Armstrong Cyclone Jet Armstrong Cannon (ネオアームストロングサイクロンジェットアームストロング砲, Neo Āmusutorongu Saikuron Jetto Āmusutorongu Hō) is a combination technique used by Seireitou Kawahiru and Raian Getsueikirite.

Overview
By combining the white flames of Seireitou's Hanullim and the path-shaping powers of Raian's Kanāji Fūshin, it creates a massive storm of black flames (most likely due to Raian's own reiatsu supplying the attack's form) that turns into a bladed arrow which is fired at the target(s) with great speed. The result is not an explosion, due to the inward design of the arrow and the energy flow crafted by Seireitou, but instead eradicates anything and everything within its range of flames and immense heat.

Behind the Scenes
This technique's name was inspired by a reoccurring item that is featured in the manga and anime series Gintama.
