Onsen is the 29th track of the DELTARUNE Chapter 5 OST. It plays when Susie and Kris talk after her conversation with Blue, when Kris and Ralsei interact at the hot spring, and when Ralsei and Flowery talk after the battle with Orange and Green.
Upon Chapter 5's release, this track used to be called Running Water 3.[1] However, it got renamed to Onsen the same day. It may still be listed as Running Water 3 on some platforms.
