Since videos are popping up online, I thought it'd be a good idea to consolidate any possible info on Ryougi into one small thread. Feel free to post any info, rumors, and rants here. I'll try to update as often as possible.
Info is still sketchy, as Japanese players are catching up but hopefully we'll see some excellent match videos posted soon. There was a recent tournament on 8/1 where an F Ryougi player (called "K") took 1st out of 22 entrants, so there's hope yet. There was one lone Ryougi player at SBO, who goes by the name Mao. Might be someone to look out for in the future.
General
Her normals are now faster. (needs confirmation though)
Knife pickup range increased.
Arc Drive and Another Arc Drive range increased.
2C duration shortened.
236 Series: Still crosses up in combos, needs reverse input (e.g. 236A, 236A, 214A to get 236Ax3)
LAST ARC BUG REMOVED
Defense has been buffed from [1.05, 1, .95, .95] to [1.05, .97, .89, .86]
Crescent Moon
6C, 236C: Does less damage, adds circuit break.
623B now comes out slower.
BE22 knives can be blocked now.
Full Moon
j.B is slower.
4C is slower.
22C damage nerfed.
Second part of rekkas (namely 236B) is said to be lenient on command input.
2B is supposedly easier to use on OTG strings, albeit the specifics are unknown.
5B: Increased range? I saw it hit Warachia on crouch at max distance, although it might be due to his tall hitbox.
Backdash range seemingly increased, overall movement seems just as fast with less recovery lag.
236A, 236A, 236[C]: Last hit can be cancelled into IH, but not if fully charged. It does do quite a bit of damage, and destroys the remaining red damage (not sure, need confirmation).
Half Moon
j.B is now slower.
j.6B is now slower.
4C is now slower.
3C has had some specifics changed, not sure if it's due to frame data or not.
There is now increased recovery on an air knife catch, and only lingers until landing.
