Persona 4 Arena UltimaxSecret AchievementThe Secret Achievement achievement in Persona 4 Arena Ultimax worth 41 pointsContinue playing to unlock this secret achievement

This achievement is unlocked by successfully hitting Junpei's Comeback Grandslam SP Skill while having his (S)trike, (B)all, (Out), and (Base) gauges full (Arcade and Network Mode only). To perform Junpei's Comeback Grandslam, input cn_downcn_downrightcn_downcn_downright+ cn_Y followed by cn_Y when you have 50+ meter gained (while on left side of screen).

Unlike most of the Persona 4 Arena Ultimax cast, Junpei's fight style and moves involve a unique gauge next to his SP Meter that works just like a baseball game. By successfully landing certain baseball moves (his baseball bat attack, specials, etc.), he can fill up these meters and earn buffs that power up his attacks with Victory Cry Install. The gauge can be seen below (image courtesy of dustloop):

Likewise to how in baseball a player must travel three bases before returning home for a run, Junpei needs to fill all three bases and hit with a baseball attack (cn_A) in order to earn a run. Every time Junpei scores a base, all strikes and balls will be reset. In order to earn a base, Junpei must do the following:

1. Hit the opponent with a baseball bat attack. (Simply press A while near opponent)
2. Deflect an incoming projectile (fireballs) with a baseball bat attack.
3. Score 4 Balls

Balls (B)
Junpei earns a Ball on his meter for every attack his opponent blocks. So simply back them into a corner and have them block your cn_A-button attack 3 times to fill them up. Don't forget, if you go over and get 4 balls then your meter will reset and you'll receive one base.

Strikes (S)
Similar to baseball, Junpei will get a strike for every time he whiffs with a baseball bat attack. So simply get away from your opponent and hit cn_A-button, make sure it misses your opponent. Getting 3 strikes will penalize Junpei with an out.

Outs (O)
These are what all baseball players should avoid. Every time Junpei does anything listed below, he will receive an out (this resets the ball meter in the progress). Getting 3 outs will completely reset every meter except for your runs. To get the 2 outs needed, just have your opponent hit you twice. Other ways to get outs include:

1. Taking damage from an attack.
2. Being thrown. Teching the throw will also earn him an out.
3. Getting 3 Strikes.

Boosting Method
Instead of attempting this achievement in Arcade Mode on Safety difficulty, you can easily boost it online with a friend under Player Match. Have both players select Junpei and follow these steps:

Step 1: Once the round begins, get near your boosting partner and Gold Burst on them by clicking the cn_LS. This will get you 100 meter to do your Comeback Grandslam SP Skill.

Step 2: Next, have your partner hit you with two light crouching attacks. They are done by pressing cn_down+cn_X button. This will get you 2 Outs.

Step 3: Hit your partner with three baseball bat cn_A-attacks to get all 3 Bases full.

Step 4: Have your partner walk backward into a corner. Now allow them to block your cn_A attack 3 times by holding away from you. This will net you 3 Balls.

Step 5: Once that is done you can simply miss 2 cn_A attacks. So step far away from your partner and just hit cn_A twice. Make sure these attacks don't hit anything.

Step 6: At this point all of your gauges should be full (be sure to check them below the screen for confirmation). Next, get near your partner and input Junpei's Grandslam SP Skill by pressing cn_downcn_downrightcn_downcn_downright+ cn_Y followed by cn_Y.

These notations are assuming you are on the left side of the screen. If the move successfully connects with your opponent, the achievement should unlock at that point.

Note: This method can also be attempted in Arcade mode, preferably on Safety difficulty. Doing this online simply eliminates the need for the CPU to behave properly to get your gauges full.
