Winter!: Prepare for holiday gaming!
You have defeated the leader of the people of the sleeping town Nanai, the Knight. Who was a step up from Frog and instead of being able to "hit, hit, hit, hit, hit, heal" it was more like "hit, hit, heal", because his attacks are so strong.
You have defeated him and it's time to remove the E Key from the dangerous spot it has been placed. You'll hold onto this Key fer a GOOD while.
And don't be stupid and not use it, this thing is handy as an attack.
If Nina's not doing anything or Ox is being useless as always you can have them use this thing as a multiple target attack, it's pretty handy. ^_~
