Fuki's passive mechanic is the karma gauge:
-Attacks using the attack (tilt) button will build up white karma on the opponent.
-Attacks using the strong button will build up black karma on the opponent.
-Attacks using the Special button will build both karmas up on the opponent.

-Upon reaching 4 white karma and 3 black karma, the enemy will be put into a karmic state for 6 seconds.
-While in the karmic state, the enemy is reduced to 0% damage, with the damage being stored, to be re-applied after the karmic state ends.
-When the karmic state ends, all damage from before and the damage dealt during is added back to the opponent, and they are struck by a high knockback upward attack. (This can be parried or dodged)
-All hits against the opponent while they are in the karmic state add damage as well as increased knockback modifier to the karmic hit at the end.
-All hits from the opponent while they are in the karmic state to Fuki reduce the knockback modifier to the karmic hit at the end.

Fuki has no chargeable strong attacks:
-Instead, she has access to a second set of aerial attacks with the strong button, as well as having uncharged grounded strongs.

Fuki's Neutral Special:
-A forward thrusting attack that applies both karmas on hit.
-Her only kill move outside edgeguards and karmic explosion, with it having a tipper hitbox that has strong knockback.
-Stores charges on hit, after hitting it twice Fuki gains a particle effect around her, and nSpecial turns into a projectile attack for 6 seconds.
-The projectile version fires a white blade beam followed by a black one, with the black one having high knockback with kill power.

Fuki's Side / Up Special:
-After a brief pause, will dash forwards / up and deal damage along the way, applying both black and white karmas.
-Can still act after either, you can use both side special and up special then wall jump and do them again.

Fuki's Down Special:
-Fuki's soul leaves her body, and her body will either stay still if on the ground or it will move around in the air towards her soul.
-You control Fuki's Soul.
-Fuki slowly takes damage while separated, but attacks from the opponent on her soul will only do knockback, not damage.
-If the opponent attacks Fuki's body, then her soul is snapped back inside and she gets hit normally.
-Attacks from Fuki's soul do not deal damage, they instead build up damage and knockback modifier for the next time the opponent is in the karmic state.
-If Fuki's soul is destroyed then it is instead just snapped back to her body.
-After Fuki's soul is returned to her body by any means, she enters pratfall.
