Obtaining Suzaku:

While in Mosperiburg in search for the Shield 
Card, you can get Suzaku as a playable playable
charactor. Defeat the fairie on the first screen,
yhen go to the area with three boars in it. 
You'll see a snowman on the southern edge of the
clearing, which takes you to a fight with Jotnar.
The Jotnar is really tough. It helps to have Ice
Crystals, Gendu Sheilds, and Pearl Hearts to help
nulifie its ice and water attacks. Once Jotnar is
defeated, return to the previous cave and take 
the right branch to find a defrosted Suzaku Jr.,
who joins your party.
