Rei, rookie mistake. Don't aim for where they are, aim for where they will be.
She catches on quick enough though.
If he's using his arm as ammo, then he can't shoot her without weakening himself. That's an exploitable flaw, let's see if Rei catches onto it.
Rei is a berserker trapped in a Mage's body. She needs to start lifting and get some Kung Fu lessons or something. Build up strength... Already an experienced boxer so the hardest part will be transitioning from sports fighting to real fighting.
Not only is he a more experienced Mancer, but he's also a more experienced fighter, too. It's gonna come down to force of will and raw power.
"I won't kill you" is the worst thing to say in a fight to the death.
Yess... Do it, Rei. The flesh is just crude matter, don't let something as petty as exhaustion stop you from kicking his ass. Your blood burns hotter than he'll ever realize! Draw out every last scrap of your latent power and then
go beyond! PURASU...
ULTURA!
...sorry about that. It was either that or a Super Saiyan joke... Or maybe Kaioken, since this is clearly damaging her body. Don't deny tha you were going for a Shonen anger/determination power up, with the prose and imagery you're using here.
FALCON PUNCH!. I'm not apologizing for that one.
Okay, I was wrong during the fight with the thugs.
This is the Shoryuken.
So Lord Orochi wants her fire... But didn't prepare Kestral to fight a Pyromancer? So, good. He hasn't read the Evil Overlord List. I'm pretty sure there's a line about underestimating the hero on that.
Now, I have to imagine that Aria and Rei aren't the only pyromancers. We've got the photo of the fireman beating fire away with an Ax. So what's so special about Rei specifically. Or at least her bloodline. Gamma said that she wasn't like any Mancer he'd ever sensed before, so... God I'm gonna have to read the rest of the series just to answer that one question.
Kestral is just following orders. The emphasis on his dead eyes in this chapter and the hints from before makes me feel that he's probably dead o n the inside after his Aves training. I'd feel bad for him if we'd seen what he was like before this, but right now he's just a threat that needs to be put down. Rei doesn't have the means to help him even if she wanted to and he probably wouldn't let her help him if she could.
The death of innocence. A life taken, in defense of one's own, but still. The flower wilts and the rest is silence.
Okay, let's talk about science! A cremation furnace burns at 760 to 1150 °C (1400 to 2100 °F) and takes between 90 minutes to two hours to completely disintegrate a corpse down to shards of chard bone, which was then ground down into a fine powder to create the "ashes" (more accurately cremains) that are either scattered, interred, or kept in an urn by the family.
But a corpse burns much more easily than living flesh, as livingflesh is much more resilient and still has all of it's fluids in it: You can't burn water, and moister makes things decay faster, so draining out the blood and lymph is one of the first steps for preparing a cadaver for funeral rights and/or cremation.
In order for Rei to completely destroy his body so that not even ash's remained in just a few seconds, she would have to make fire that burned as hot as the surface of the sun.
At least.
The sun burns at roughly 5505 degrees celsius. Or 9,941 °F
This means that Rei, in a pinch, has enough power...
Well, I'll let the expert say it.
I'm not apologizing for that one, either.
(Almost 10000 would be more accurate, but that's not a meme.)
