B is leading yas! But can i recommend tho even i voted for this xD first is The Greatest Start because the fresh new start? Something like that i have no better word for new, start and fresh? omg xD

Second one is The After Sacrifice: _ you can put whatever you want in the blank space or not.

But honesty Our Greatest Desire sounded more great xD

Well my idea but i hope from that you can get a better idea and title even more way btter than mine for the sequel! Me being the aspiration sounded so overwhelmed but lets not get ahead of myself HAHAHA good luck with the sequel btw!
