Siren is my top!! Marian is close to overpower Siren in my Top 1
I also like Cinderella, Doro, Liliweiss, Red hood, Snow white, Grave alias Abe - I actually like all Pilgrims i am a bit biased on that they just left the strongest impression on my storywise and also outstanding Characters (I am not so fond of Hansel and Gretel eh) but well
Counters I like Anis the most due her character but backstorywise I think Neon left the strongest impression on me.
