I finished this today- and before anyone gets irritated, I'm reading the translated version. Anyway, the story is very funny - the amount of sheer hilarity caused by her simple misunderstanding has slowly grown into a worldwide adventure with her being the ultimate cheat character. Think Saitama except he thinks what he can do is normal and everyone else is just playing along. That's what Tilea is like. I really enjoyed the series, but it isn't a very serious thing. That's entirely defused by Tilea's ongoing belief that it's just an extremely bad case of Chuunibyou. The art isgood, and the characters are very fun to witness. The story is pretty good, but it does suffer a little from the stretches Tilea goes to in order to make the "misunderstanding" constant. It's also funny how the demon generals respond to her "playing" around with them :)
