Oh my god.
Just.
Wow.
Even though Dio is such a douche in game, this makes me really feel for him. All of your description and introspection from Alice really made me see this torn-up rag of a person as Dio. The ending was heavy and made me sit back, think, holy shit.
This is really something incredible. Sorry about my lack of good words to say- I just can't express properly how this story made me feel.
