She's 15. The manual says so, as does the in-game encyclopaedia. All of the other characters look and act their age. Which is to say they are a bunch of teenagers out to save the universe complete with their own old-aged (he's like, 35!!!1!) cyborg super scientist 'alien' friend. :sigh: Reimi and Feize aren't bad and Meracle the cat-girl-thing manages to be both funny and likeable. Anyone who considers the obligatory sappy angel type to be a giant chicken, and stalks her with a knife, fork and bib is alright by me. I'm so going to make those two share a room on my spaceship when the sappy angel type formally joins up.

At no point at all (so far; I'm about midway through the story now) does it bother to explain to you why Lymle is like she is, not so much as a hint. You have to go look her up in the encyclopaedia, at which point you're told that when she was 6 she opened a portal to a demonic realm and did some crazy magic on herself in order to stop herself feeling or growing because if she hadn't she would have gone insane. I only saw the explanation because I was searching for something else; until then I believed the manual had a typo and she was intended to be 5.

On the plus side the game's finally given me another massive planet to explore with loads of side quests and goodies, and enemies which are reasonable to fight. So at the moment it's enjoyable.
