Z was executed really well, I really like his character, the playful flirty bantering is just right-up my alley and I adore how it was played out. This VN is one of the few that I really really am excited to play more of, I absolutely love it! It's seriously great, I can't wait for what you have to offer next!
EDIT : God, okay, so I found the secret ending and all that, and it just ASDFGHJKLAAAA it just made this game more intriguing, I really adore this I sincerely cannot wait for more. Z is so mysterious, I would love to get to know the lore and just-- anything in general about this game, its so so so good >:DD
