"...That's basically the situation. All you need to do is control the sea beasts so they don't swim into this area." Reynaud briefly explained what 'Song' was supposed to do.
As for why, Reynaud's explanation was: A dangerous entity has appeared up ahead, utilizing sea beasts for sacrifice to enhance its power. If it's not stopped, it will threaten all life in the Mist Belt.
"Song, I'm counting on you."
X3 maintained a cold expression. After hearing Reynaud's words, she scoffed, "Why should I believe the words of a traitor?"
Reynaud's expression was bitter: "You still think I'm a traitor? In that case... I have nothing more to say. But, you know me best; you should understand I have no reason to lie to you."
