[ Rean finds a chair to seat on before catching his breath too. ]
Thanks back there. That was amazing. [ Rean pauses and decides he should ask anyway. If Kazuki doesn't want to talk about it, then he'll drop the subject. ]
If you don't mind me asking, what was that?
[ Monsters turning into crystals isn't really anything too far-fetched for Rean, coming from a world where monsters were a reliable source of sepith crystals. Orbal arts allowed them to perform arts all sorts of arts that people must have labelled as 'magic' before the orbal revolution... but it doesn't look like Kazuki has something like that on him. Rean doesn't, either. ]
