“Have you no control? Mad dog!”

Archer cursed as he accelerated Vimana and soon approached Berserker’s back, close enough that he could kill him for certain. There was now so little distance between them that the opponent would never be able to evade the barrage of Noble Phantasms from Gate of Babylon regardless of his transcendent mobility – however, this decision backfired on him.

From the underside of the F15's body, scorching fireballs, like will-o'-the-wisps, slowly scattered in succession, washing over the nose of the trailing Vimana.

“What!?”

Originally, this armament called a flare dispenser simply launched out decoy heat sources in order to throw off the enemy’s heat-seeking missiles. However, as a result of being eroded by Berserker’s prana and demonized, they have even transfigured into tracking incendiary weapons. Based on their dogfight up until now, Archer made the hasty conclusion that the enemy doesn’t have a way of attacking against an enemy behind him, and therefore couldn’t cope in time to this unexpected counterattack. The bow of the Vimana plunged into the hive of roaring fire balls, lost control while surrounded by the crimson flames, and fell towards the surface of the river in a spiral.
