Haven't played this in a while, so a bit late to the party,
But holy shit that Emma solo ending.
I'm gonna be honest that is the first time I've ever teared up to an adult game XD
And that reveal at the end, I'm more than hyped now for the next game, and I'm viewing this game and Sicae completely different now with the prospect shown.
Does make me wonder though, will the next game be set in an alternate universe, or will the non-Emma solo endings also have post-credit scenes to tease the next game

either way I am looking forward to whatever NiiChan cooks up.
