**SUPER IMPORTANT!!! DO NOT REPLAY THIS LEVEL UNTIL YOU HAVE GOTTEN THIS ACHIEVEMENT! Since this game overwrites your playthrough when you replay levels, when you load this level again, the Tengu will not be there anymore and the game will think you did not do the quest and saves that over your first playthrough.

Reward: Cherry Bomb.
And thats that! Achievement should pop as soon as you finish the last quest.
