About two weeks ago I was trying to go to sleep but I was then the subject of divine intervention. The image of Ralsei's idle battle sprite from chapter 2 on top of the flag of New Zealand came into my head clear as day and I have not stopped thinking about it ever since.
This is the only good Deltarune theory. I don't care who the knight is. I don't care where Dess is. I don't care whatever the fuck is going on with Gaster. (/s)
Ralsei is a Kiwi.
I'm not even from Aotearoa, I'm Australian. But ever since that night I've imagined Ralsei with a Kiwi accent and it is actually perfect. I can't describe it. This is the only good headcanon. I will defend Kiwi Ralsei until the day I die.
