Disgaea 4 Return (JP) - Next Episode Segments and Ending Credits

Ending Theme: "Forever Flight" by Mizuho Yasuda
This is a mode focusing on Tyrant Valvatorez and Artina so of course, there will be no more sardines in the Next Episode segments.
Valvatorez: No more sardines!? Well, I must remedy that quickly! SARDINES! ARE! BEAUTIFUL!

I would love to know it the lyrics has something to do with Artina and Val... Does anyone know where I can find lyrics from it?

[@DurableTomb]

I hate to bother, but do you know if one can unlock Past Artina after completing the new scenario? Also, any idea if the skins for the Fighter and Armor Knight that are used for the human units are available for use afterwards?
