As pointed out in the Japanese site link, part of Yang's battle script is not properly executed.
His script looks like this... (according to the editor)
Battle script 0xA8:
Always
Battle Message $E
Target Kain
Fight
(End of Turn)
Battle Message $F
Kick
(End of Turn)
Battle Message $10
Target Kain
Fight
(End of Turn)
Battle Message $11
Kick
$F3 to $F8 - $81
Counter script: 0xA9
( $2 $0 $0 $1 )
If Attacked by Tellah
Battle Message $12
Cast Dummy ($AE)
This script is parsed wrong, but here's the jist of what it is supposed to do:
Battle Script:
While targeting Cecil, display message 0xE and attack him.Display message 0xF, then attack with Kick.
While targeting Cecil, display message 0x10 and attack him.Display message 0x11, then attack with Kick.
Repeat sequence
Counter Script:
When Cecil deals physical damage, there is a random chance to execute the following script... which is to display message 0x12 and end the battle (by using spell 0xAE).
Note the bold.. this is never executed on a normal run. There's a simple reason. This was intended for Dark Knight Cecil.. not Paladin Cecil as the battle script is never normally executed. However, there's a lot more happening here than meets the eye.
1) Yang appears to attack with one of Cecil's Dark Blades. Really, I'm not kidding.
2) The random battle ending falls along the same lines as the random Lightning killing Odin sequence. There's a low chance of it occuring (less than 10% I suspect). Note that this sequence expects Paladin Cecil's physical attacks as part of it.. which is ironic, given the battle script was meant to focus on Dark Knight Cecil.
Here are some random thoughts and opinions to this..
1) This was intended to be part of some auto-battle sequence. It was never finished since Yang attacks Cecil as part of the battle script.
2) Characters attacking with a weapon as an enemy was something never truly finished. Obviously Yang attacking with Cecil's Dark Blades was never meant to happen. Some hacking to change this would be interesting, but it would need a lot more research. This is why this section was never executed.. it would looked rather fucked up.
3) Yang was meant to be encountered in a different situation.. which is not what the current finished product happens to be. For all I know, you were meant to battle him and he meant to attack Cecil intentionally. Perhaps the demo picture with Dark Knight Cecil, Kain, Yang, Rosa, and Young Rydia may have had its origins be validated.
From the original thread (which will be killed in due time) -
http://boards.gamefaqs.com/gfaqs/genmessage.php?board=929937&topic=42923762i have a copy of the original final fantasy 4j that i bought a few years ago, kind of on a whim. this being the most active ff2/ff4 forum, i thought it may be the best place to ask.
let me post the pictures:

http://i264.photobucket.com/albums/ii181/bond697/photo2.jpg
now, they're blurry because i took them with my iphone(sadly, no scanner).
let me explain what is going on in case you can't make them out. they are of the same image on the original ff4j box. i can't remember the monsters' names, but i can describe them. one is a green "gargoyle" with wings, and there are 2 "birds", maybe "eagles"? as i said, i can't recall the names. anyway, the odd part is that they're fighting in the castle setting, like when you defend the castle with yang, edward/gilbert, and cecil. in the picture, it seems that rydia is casting fire(2?) on an eagle creature. here is your party with their hp levels:
->(back row)
kain 550/550
->rydia 307/310
dk. cecil 599/600
->rosa 453/454
yang 860/860
i don't think that this scenario happens at all in the game. if it does, could someone please let me know where? it's a neat little look at what might have been, i suppose.
i've looked through the manual, but haven't found any other out of the ordinary pics like this. if i can get access to a scanner, i'll get a better couple of pictures.
