The Witch, Rebellion's confirmed last book, was just previewed , and they didn't skimp on the details this time!
On one hand, they confirm she's basically the strongest, both in stamina and power, and her specialty is the "soul control", apparently what we knew as her "cursing power" that she used on many beautiful fighters, that might enslave her opponent in one-shot (after a certain preparation first)?
Plus, here's the first confirmed "Unholy Pose"! One of the poses devised to counter the Holy Poses, no word yet if this one is "Control", "Corruption", "Despair", "Pain", or a new one.
On the other hand, she doesn't come by herself, as a proper last boss, she brings some underlings to the fight! Namely, Airi's pals, the maid ghosts here... and I'm pretty sure they say she comes with a "guest beautiful fighter" too, did she really enslave one of the girls that didn't come back for Rebellion...?
And I wonder, can all these crazy things fit in just one book? We'll have to see next month!!
