花王 (原聲帶)

「

When I parade their body around town
Everyone will finally realize how right I was.
That I wasn't "crazy." That they weren't, "conspiracies."

」 ——Asgore, Chapter 5

Flower King is the 22nd track of the DELTARUNE Chapter 5 OST. It plays during the cutscenes where Asgore talks about his notes and research into the Dark World, and while the party climbs the vine from Flower Castle's foyer to Top of Castle.
