This is so awesome and I love Toriel seeing the first form of ultra sans and saying that ultra sans is bigger than my house it's very realistic and also funny along 😅
Toriel: Who taught her to swear!? Was it you Sans!? Sans: Knowing myself, I wouldn't speak that in front of the kiddos. Especially with young Patience beside him. Toriel: Then who taught her? Ashore? You wouldn't have spoken outloud in front the children, right?
Great job (except for the long-winded explanation part). It worked especially well with Alphys, Papyrus and Undyne (although sadly Chara's participation was ignored.)
Seraphim isn't biblically accurate to an angel, he's just sans with 7 human souls, and also seraphims aren't gods, they are a different type of angels, but aside of that the video was pretty good
