Tsukumo's getting his own harem, eh? Neun, Glorya and now Liona. Although it's clear he prefers Liona and he's more like "prey" to Neun and Glorya. I welcome any and all side ships in this story... Well, except for Diedhauser and Emilia, they don't count since she's only got one-sided feelings for that prick.
I don't want to see a "captured" arc especially since they have a clear time limit on this mission, but I wonder how they'll get out of this bind.
