Star Ocean EX EP4 - Heraldic Magic

Rena and Claude decide to visit the king in Cross, who tells them that the battles with the monsters on the continent of El, where the Sorcery Globe landed, are still going on. After making sure they will not change their mind, the king gives them a passport to go. Back outside, they meet Celine Jules as she is being attacked, though she does more damage to the attackers than they to her. But, because of him stepping in, Celine makes Claude her bodyguard. Celine tells them that she is a treasure hunter and is searching for the treasure of Cross Cave and eventually talks them into making a detour to the cave while on their way to El; although the cave is in the wrong direction. After searching the cave and getting lost, thanks to a false map that Celine had, they stumble onto a chamber with the treasure. It turns out to be an old book written in a language that they do not know. After coming back out of the cave, Celine tells them that she is going with them.
