New update:
- You can recruit a new character after beating the game, it's one of the angels Arekishi did, but as a trio. You just need to complete a small event and that's it (probably also have the single version one from random encounters).
- You can now give the Ring of Promise in the final camp to Chrome, both young and old version of Promestein (and probably fused too), Kagetsumigi, Constanze and the Queen of Remina.
- The character you've given the ring to will have a special dialogue in the castle instead of the usual one. In my case, Ilias is basically asking to have a child with Luka, saying she's being very serious about this. Micaela (Fallen) basically acts like a yandere, tells Luka she wants to live with him after everything is over and be surrounded by children, but if he cheats on her she will kill him, then his lover, then herself.
- New H-scene with Constanze.
We should probably expect more people to give the ring to in future updates, so I hope you have a save for that (really wish you could reset your choice when you redo Chaos route). Also that the post-game content will still take more time to complete.
