"- “Don't you see? She can't go there alone. You realize it must be incredibly dangerous over there.” - “Yes, I do know it, but I also know you very well. You and me are alike and I can see that you are reacting in the heat of the moment.” - “Ok, sis. What do we do then? Just hang around like bananas waiting to ripen? Weren't you the one who wanted to leave your boring little life?”- “Anyway, I'm not going to have the last word here, am I?”- “No, no compromises today. Let's go and have a look on the other side and put an end to these mysterious visions once and for all.” - “Right, I'll go first then if you don't mind.” - “Let's go.” "
It might be a hint for an exclusive Rare NewBlood? You never know. Maybe this is a different portal or a link from the other side?
I did remember that during Ratanah Mt's announcement, there was a comic featuring her.
Wonder if another comic will appear relating to such?
Just my speculation though.
I am thinking Chiara Cr and Dalhia Cr reasons
Sis might be used more as a sign of respect when Dalhia Cr left she took Chiara Cr with her to join her crew creating a story connection.
Only characters I could find with that connection without being in the same clan.
I believe they are following Sigma Cr who left for a perpendicular Dimension by the call of Guru Cr which might connect to the other clue that Newell has the key to opening the portal.
