I can't read any of this so I'll just try to explain it according to the game. And I skipped some scenes cause Leon's not in them; if you want to see them, go buy the manga. The quality in the manga is better too since I shrinked the images by 35%.



kawaii!
aww, Leon's hiding behind his big brother Claude
watch out!
Rena heals Ernest and Bowman and Claude fight the monster while Leon hides
bowman: Leon! come out and help us. don't you know how to cast magic?
he's scared cause he never saw such a monster in his books
... he's probably saying something like there are many things in the real world that you can't learn from books
Rena: bowman-san...
leon regains confidence
"The purities that exist within contamination, bring to life a core that is deeper than the core itself, rain down upon those blood thirsty ones who stand in my way!"

that spell was translated from the anime by Soldats. I'm not sure if it's the same as this one.
ACID RAIN
Wow, it's more powerful than the one from the game



Watch Out, Leon!
Ernest saves him just in time
and Claude finishes the job
So Leon and Bowman finally become friends?
Claude lets Leon hold on to the energy stone



aww, even more kawaii!
Ernest gets left behind
oh, this is sad



leon: look mama, I did it
leon's mama: Leon, don't talk in front of the king

and he goes straight back to work without any compliments
