*Tilith: So this is a town in Ohbanahara...
*Tilith: The buildings look and feel totally different from what we have in Elgaia and Grand Gaia.
 	
*Seria: Yeah...
*Seria: Honestly, I wish we had time to stop and do some sightseeing, but...
 	
*Tilith: I know. But first we have to rescue Suzune!
 	
*Sakunoshin: The palace is this way.
*Sakunoshin: Once we cross this large bridge...

*Sakunoshin: You're that woman who serves Genba!
 	
*Seria: ...!
*Seria: This air of malice... She's no ordinary soldier.
 	
*Raka: Hehe, I'm Raka.
*Raka: I suppose you could call me a swordswoman who serves Lord Genba.
 	
*Sakunoshin: Vile woman, you mean to slay us and put a stop to our efforts to rescue the princess?!
 	
*Raka: Oh, no, nothing so crude as that.
 	
*Raka: Or rather, I could care less about those little girls.
 	
*Tilith: Wha?
 	
*Raka: You're the one I'm interested in, .
*Raka: You came to this world to search for the sealed god, didn't you?
 	
*Tilith: ...!
 	
*Seria: How...do you know that?
 	
*Raka: Hehe, indeed, how could I?
 	
*Raka: If you want to know...ask me with your swords!
