This is my opinion and also contain spoiler.
Deltarune is NOT prequel or sequel to Undertale
Deltarune is just the ALTERNATE UNIVERSE
Toby Fox already confirm now
Why is isn't prequel to Undertale?
• Asriel was in college so basically he's grown up now
• The grave where monster died is, Gerson, Shyra, Muttler, Crystal. Four of this monster was from Undertale.
Why is isn't sequel to Undertale
• Sans just know Toriel
• Undyne didn't know Alphys
(Sorry that's all I know)
About Kris, people think that Kris is Chara because of green shirt with yellow stripe.
Kris is Kris
In the end, Kris was being control because the way they get out of bed and the creepy walk.
If Kris is Chara, they shouldn't have to get their soul out of their body and throw it in the birdcage.
That's all I can say now, thanks for your time to read.
