Hint to this game:
1) Before "Combat Basics Class" (Arashiya Forest mission) buy a "EnAqua Crystal" on the stand selling crystals right under Vissage House.
2) When you're about to get the "Arashiya flower" one student will put the flowers on fire. Before leaving use the "EnAqua Crystal" to put out the fire on the flowers. Note: you will fail the "Combat Basics Class" anyway.
3) Once retaking the "Combat Basics Class", if you used "EnAqua" on the Flowers you will get 2 "Arashiya Flowers" instead of 1.
4) Do not use these flowers, you need 2 "Arashiya Flowers" to make a special armor with self heal abilities right after the fairy forest.
5) In "Soulstice" house you can get "Green Tea" on the desk where you save your game and exchange it for many itens with a boy sitting in one of the tables of this same house. He has a tea pot in front of him.
6) In "Foxhelm" house you can get "RootBeer" on the desk where you save your game and exchange it for many itens with a boy sitting in one of the tables of this same house. He has a "RootBeer" in front of him.
