I used the Brightmoon utility to extract the IN sprites, but it appears to be missing one. I'm not sure if it is from the game or not, but... It's that Pheonix that appears behind Mokou.
But there is another one in the game, that is an almost a kind of a copy of it. It's a little brighter, and the black backround of it is completely transparent, leaving only the reddish glow. You can see it in this capture.
It's also the one that pulses out when a new spellcard starts.
Does anyone know how to get this sprite? Is it some sort of effect or an actual image in the game? Or at least how to make it? I'm trying to collect ALL the sprites from every game.
