-That's not Shantotto, that's Crystalchan, a fellow taru. Shantotto doesn't have a ponytail, plus she's never worn that outfit in-game.
-This drawing comes from the MSPC #30, and is a spoof on how Shantotto cursed someone in an in-game quest-line. Kealii uses one of her staves to curse Apocalypse (another taru) into a toad.
-Toad is an old BLM spell, so I'm not sure why you said "Shantotto isn't a WHM, just saying..."
-And thanks, you made me explain the joke, which means I fail at comedy. ;3 /fails.
