So Aika is the true Mage of Exodus. While it was painfully obvious that all the clues were pointing to her especially during episode 12/13, the wonderful misdirection made me think it was Mr. No Spine instead. And the best part? Still had an inkling that it was Aika still all along, so when this revelation came, it didn't feel it was cheap nor that it came out of nowhere.
So yeah, again, all I can do is
towards Okada. Brilliantly done!
But yeah, Aika is now getting loads of screentime. Which is awesome, as I LOVE HanaKana's take on Aika's voice.
