Hishou Nichirin Zan

Hishou Nichirin Zan (Flying Day Ring Slash) is one of Geese Howard's Special Moves in both the Art of Fighting & The King of Fighters series, first appearing in Art of Fighting 2 originally used by his younger self.

Description
Geese jumps high bracing himself with his following arm, then upon reaching his peak slashes outwards with a knife-hand motion, leaving a trail of chi behind.

Originally used by his younger self, it returns for present-day Geese in KOF 96.

The version causes a ground bounce.

Strategy
Despite being a DP that launches Geese in the air, this move is strictly for use on grounded opponents. There are zero anti-air properties with this move.

Against grounded opponents, however, it makes for a great mix-up, as well as combo filler. The version works as a decent callout, technically negative on block but, much like his Raikou Mawashi Geri, you have enough time to counter a predicted punish. The version on the other hand, is the one you'll be using the most, though, as it's not only safe on block, but crosses up and delivers a hard knockdown right next to Geese, which can be followed up with Raimei Gouha Nage, or if you want to really get nasty, an OTG Raging Storm into over 50% damage off a cross-up knockdown. Another great addition to Geese's oki guessing game. The version is also a great combo extender, putting opponents into a flipped state right in front of you, giving ample time for a follow-up (usually being a Fudou Ken). Also acts as your follow-up to a wallbounce.

Stating with the KOF XV Patch ver. 2.10, The version can also cause a ground bounce if used as a Counter Hit, allowing Geese for strong follow-ups as in the  version of the move.
