Footsies, or The Neutral Game
What follows are some of Mika’s basic tools for dealing with footsies. Although getting your opponent into the corner is always the primary goal, Mika has sufficient tooling to be able to handle herself in the mid-screen. Players familiar with an abare-heavy style should feel right at home.
 s.lp/c.lp arguably Mika’s best normals. 3f startup and 2f active for both standing and crouching, good range, special and CA cancelable. Great for interruption or 3f punish opportunities. The standing version has slightly more range than crouching.
 s.mp can link into lp, mp, f/b.mp, s.hp, s/c.lk, or c.mk - with -2f on block, you may be giving up your turn by fishing with it.
 f.mp/b.mp has an excellent hitbox and is active for 4f. As it is cancelable into passion press (pp) and can be linked out of on counter hit, it is a tool worth fishing with. Like s.mp it is -2f on block.
 c.mp should only be used as a gimmick on the ground and will whiff crouching opponents. As an anti-air, is it excellent and sees heavy usage at any level of play.
 s.hp is another of Mika’s AA options and is used for heavy punish combos as it can be linked from s.mp.
 f.hp (Lady Mika) is one of Mika’s signature moves. On counter-hit, it causes CC (float state), and on block is +3f. On point-blank block, Mika is in range for an ex.typhoon. Has some value as an AA.
 c.hp moves Mika forward with a respectable 6 active frames. If she connects early in the animation, expect to be punished as it is -4f blocked, but correct spacing (or meaty) can mitigate. Commonly used as a whiff punish (to follow a retracting limb), as a VT canceled normal, or intentionally whiffed into a command throw.
 s.lk is a very standard SF s.lk. Although not special cancelable, it can be canceled into her target combo (s.lk xx s.mp). On counter hit it can be linked into itself. A good tick normal.
 c.lk as a good normal for fast low hits. The hitbox is slightly lower than the animation implies. Useful for pushing your opponent into s.hk or c.hp range. Another good tick normal.
 s.mk is likely Mika’s most important footsie normal against most of the cast - spend time learning how this normal works. Tap or hold forward to introduce forward movement to the move.
 c.mk can be used as an AA for some situations giving Mika a low reset. Decent footsie poke.
 s.hk is a CC normal best used at max range during footsies exchanges - makes for a good poke at the end of a block-string. Goes over lows.
 c.hk is a slide sweep which, if timed well, can get under fireballs and hitboxes of that variety. Very punishable on block.
 ch.hk takes 35f to start-up then propels Mika very unsafely about a third (maybe half?) of the screen. On block or hit it’s positive, creates a grounded spinning CC on counter, and can be stuffed in a variety of ways. Great move, but carries a high risk if used without smoke and mirrors. Links into lp or s.lk on hit.
 lp - a standard downward angled air light.
 mp - Mika’s air-to-air when her opponent is above her.
 d.mp (forward jump only) dramatically slows Mika’s horizontal trajectory and she drops down with a hitbox covering her descent. Will cause knockdown if it connects and is incredibly unsafe (24f) on block. Use as a gimmick cross-up (or fake) or as a standard trajectory manipulator.
 hp - a run of the mill close-ranged air heavy. God hitbox on the bottom of Mika.
 lk is a standard light cross-up. Stays active for 8f (good for avoiding air-CC) and works as an air-to-air.
 mk works as a long-range air-to-air when Mika’s opponent is above her (long-range version of mp).
[*] hk - this is the king-pin and it behooves all Mika players to learn the action on this bad-boy.
Peach is Mika’s range finisher and has some bootleg value as a movement tool. All versions of peach are vulnerable on block - unless you can land a meaty (non-EX). During footsies, there isn’t much call for non-EX peach outside of combos. hp.peach can be used to get over fireballs and close distance, but it’s a risky move, so apply with caution. EX peach is an excellent punishment special - the startup (5f) is great considering the range it has and it attains 1 armour hit from frames 3-9.
Brimstone and Typhoon
Mika isn’t hurting for AA options. Between her 3 (c.mp, c.mk, s.hp) good AA normals, ex.wa (wingless airplane), c.hp/c.hk (cross-up avoidance), good selection of air-to-airs (lp, mp, lk, mk, hk), and other, more esoteric options (f.hp, for example), she’s quite capable of dealing with high attack vectors.
Mika’s most used AA is her c.mp - by far. c.mk should be used for low resets or against incoming attacks which are too active for c.mp to deal with - the height it can connect at is sufficiently low that most air moves aimed to stuff c.mp have begun recovery. c.mp and c.mk are a pair and should be used as such.
s.hp (and to a lesser degree) f.hp work as long range AA normals. If Mika’s opponent prefers to try and stuff c.mp/c.mk by using a slightly longer ranged jump with a long poke, these are good options to try.
Wingless Airplane is an excellent AA tool and the EX version is invulnerable between frames 5 and 15. Because Mika will swap positions with her opponent, some thought will be needed when using this option.
There is value in taking to the skies when defending or pressuring a jumping opponent and Mika’s air normals are generally good in that area. Notably, mp can be used early when dealing with “floaty” jumps or air specials (like a Claw wall dive) and hk is active for 7f making it a versatile pressure tool in the air.
Using V-Trigger during footsies
Mika can’t really fish for counter hits too easily during footsies as ch.hk and f.hp have limited value at her mk range which is where Mika does her work - most of Mika’s counter-hit opportunities occur on wake-up.
s.hk has value in this regard. It starts up in 17f and is active for 2f and leaves Mika at -4f on block.
Not a compelling sales pitch, I know, however, it does go over low attacks and has sufficient range such that punishment can be difficult or impossible depending on the situation. On counter hit, it causes a spinning float state (ex.peach is the best option after this happens) which allows standard wake-up pressure. The key to success is liberal application with good timing.
As @S-Laughter pointed out, in not so many words, if you’re going to give up your turn anyway, s.hk makes for a solid full-stop at the end of an exchange and, who knows, maybe you’ll get lucky.
