Even if Ryu wasn't in DOA, I'm pretty sure all the fans would just be playing NG right about now since that's his home game. He's basically untouchable.
If I called Leon's 6P a "Junyo 1-inch punch," would it be 1-inch punchlike?
I have never seen an Izuna drop in any media that didn't consist of dropping the opponent into the ground headfirst. That is the one consistent feature across all izunas.
Izuna Drop: A Hayabusa clan special technique. Momiji does this by launching her opponent in the air, grabbing them and doing a spinning pile driver into the ground.
Izuna Falcon: Momiji's variation of Hayabusa clan's Izuna Drop, while in the air with her enemy, she stabs her enemy downwards with her Naginata and slams them full force into the ground. Unlike the other techniques she learned from Ryu, she learned this move on her own during her travels.
