Sprite Messenger! I finally found out the reason behind the nameless fire!
Turns out there's this Elemental Firelord who's been wanting to join our Water Festival. But, you know, his body is a bit 'unique' and doesn't exactly agree with water balloons. So he had never had the chance to really join us and have fun. Until now! This time, the water we used to make the water balloons was imbued with magical power. The Elemental Firelord was drawn by the magical power to Ilya, despite knowing he should have stayed away.
Long story short, he got carried away by the festival spirit. As a result, nameless fire burst out from his body.
Take this--a special Super-Cool Giant Water Balloon I made! Show the Elemental Firelord our hospitality! You can probably find him at the back of the Magic Academy (97, 172). Valer gives you the Super-Cool Giant Water Balloon.
The Water Festival this year is a lot of fun! Wouldn't you agree? Nothing makes me happier than seeing everyone having a good time!
In other news, it seems you've also helped to put out the nameless fire! I'm looking into the reason behind the sudden appearance of the nameless fire, and I've already had some promising leads. I'll keep you posted.
Here's your reward! Come back and join the festival again whenever you have time!
