Deltarune's is gonna end with the roaring, the safe haven during the roaring will be castletown, aka the Angel's heaven. It is the one place everyone you recruited is safe (Noah's Ark) but the only way to stop the roaring is to seal the grand fountain as it is the source of pure darkness and the main fountain.
Sealing it will make the dark world unaccessible to the light world but all the darkners you recruited throughout the game will be saved, they all still exist, both worlds are saved even if they can't interact with eachother. You as the Angel are banished to the dark world too and can play minigames and shit there and go to the dojo to practice.
Snowgrave is going to probably get to that same point but instead of banishing the angel's heaven you instead use Noelle to freeze everything and keep everything in a perpetual state where both worlds exist connected but, y'know, frozen or some shit lol.

No rpg party is complete without the nameless, identityless, faceless eldritch being that is a player insert with no history, no connections and no need to eat sleep, drink, or otherwise that somehow is the strongest person in the party.
No I will not accept Kris.
But I do agree the weird route will lead into making a tropish traditional rpg. The Hero or the Vessel, the love interest friend or Noelle
But I wonder who our third will be.
