Oh? Oh! That’s so cool! It’s almost like…! Uh… [ Jack stares at her bloody hands, then forms two V symbols with both and grins! It doesn’t look menacing at all!] While apart, it looks like a symbol for victory~!

[ Jack glances between Merlin and Medusa, now blinking in confusion. Then recognition flashes over her face.]

Eh? Did you guys reveal your True Names? Okay! We guess the jigs up!

[ The darkness now makes her appear more menacing as she introduces herself!]

[ Kyosuke pales a little after hearing that. It probably wouldn't be wise to tell them she's a wraith composed of ghosts just after they vanquished the other one from before.]

T-the infamous serial killer?!??

[ Jack flashes them both a cheshire smile.]

Yuuuup! Don't worry, we won't dismember you!

[ Like that'll be any comfort whatsoever!]

It's not just mythological heroes either! There's historical figures.... fictional ones, concepts... my best friend is a concept for nursery rhymes~
