@Kozutan I agree this chapter is kinda bad but she could use water magic from the 1st chapter, it's just really weak, it's not sudden at all and she even used it in the life eater arc. She managed to dehydrate kidnapper dude just because of the desperate situation, that made her act desperately in a sudden "AAAAAAAAH ANYTHING GOES TO STOP THAT DUDE, OR PRINCE DIES AAAAAA WHAT DO I DO- AH WAIT I'LL JUST DRAIN THE WATER OUTTA HIM" moment(extra despair added by me to make a point but I think that must be how she felt, lol), if she had thought about it before she'd certainly use it earlier
The ridiculous part is how dumb the kidnapper was, in my opinion... How is he one of the three most powerfull dudes in the country with that peabrain?! Geez. Is he a puppet lord controlled by something else? He's so dumb.... :v
Also the epidemic is kinda sudden, but in my case I just accepted it as plot device, not really the best one and we just had it not long ago, but it makes sense even if it comes outta nowhere... I mean, a lot of epidemics start from seemingly nowhere in real life and where and how it started is only discovered a long time later, so... yeah o3o
