J1 - 30 - a bit laggy, cancels into SI
J2 - 40 - low endlag, cancels into WJ1 and SU
J3 - 80 - cancels into dash and WU
WJ1 - 80 (20x4) - cancels into WI, low endlag
WJ2 - 130 (20x5/30) - knockdown, virtually no endlag
SJ - 60 (30/30) - good out of shield combo starter, cancels into J1
KJ - 50 - great combo starter projectile
U - 40 - burst combo starter and approach tool, safe since it doesn't activate on whiff, cancels into J and U2
U2 - 80 - knockdown projectile that can only be activated on U hit, very low endlag
WU - 100 - anti air knockdown projectile, cancels into dash
SU - 150 (20x5/50) - anti air and combo extender
KU - 90 - good aerial mixup
I - 270 - subpar projectile
WI - 270 - up projectile
SI - 500 (400x10/100) - barrage of 10 projectiles and a huge slash
Safe moves - J3, WJ, KJ, U, WU
Whiff punishes - SJ, U
Dash coverage - J, KJ, U
Anti airs - SU, WU
Mixups - KJ is a great tool to start combos and pressure, which makes aerial mixups really helpful; dash dancing and U approaches are the core of Ogichi Shikai's pressure; SI can be used in neutral if the opponent doesn't have the resources to dodge it, such as with a ghost jump
Combo routes - bnb - SJ J1 J2 SU WU/WI; juggle setup - after SU, the opponent is in perfect position to get hit by SJ, and turn around SJ or U can cover dashes through you if they're facing you
Shieldstring finishers - J2 WJ; J2 SU WU L; J3 L; J3 WU L; SJ J; WJ1 grab; WJ1 WJ2 grab; WJ1 WJ2 J; WJ1 WJ2 L; U J; U U2 grab; U U2 J; U U2 L
Zoning - KJ is Ogichi Shikai's only zoning option, and it's more of a pressure than zoning tool, but it can work with good aerial mixups to effectively zone out characters that don't have good anti airs
Out of shield - SJ for guaranteed punishes; U to contest safer pressure
Zone breaking - KL KJ/KU is a fast burst option that covers a lot of ground quickly, while dodging projectiles
Reversals - SJ and U can punish dash coverage attempts; he doesn't have any strong option against okizeme besides dashing
The one tool Ogichi Shikai lacks the most is a consistent zone breaker to punish projectiles and other ranged options, so whiff punishers can help him a lot
