Gun

Gun is Joker's Neutral Special Move. He can fire his guns either forward, upwards, downwards or around himself in midair.

Gun
Joker will fire from his gun forward. If the control stick is tilted up, he can also shoot it upward. If Joker is in midair, he will spin while shooting the gun. If the control stick is tilted down while in midair, he'll shoot downwards while carrying his momentum. He'll shoot up to 3 bullets if the special button is held, or will rapidly fire bullets if tapped.

This attack does minimal knockback and damage, and they can be reflected/pocketed/nullified like any other projectiles.

Gun Special
When Joker has Arsene with him in battle, his bullets will do more knockback and damage, and he can shoot up to 5 bullets when held. It is noticeable by its blue flame.

Origin
In Persona 5, each of the Phantom Thieves has a ranged weapon. Unlike their melee attacks and Persona-assisted attacks, ranged attacks do not consume their turn, however, they have limited ammo which will only refill if the player leaves the dungeon. Hence, the player has to use each character's guns strategically, as each of them does varying damage with varying ammo. It is especially helpful if enemies with gun weaknesses are encountered.
