Asriel = another name for Azriel (AKA Izrail, Azrin, Izrael, Azrael, Azrail, Ezraeil, Azraille, Azryel, Ozryel, or Azraa-eel), a Hebrew Angel/Demon, the God of Death, and some say he is the same entity as Sariel (AKA Seriel, Sauriel, Surya, Saraqael, Sarakiel, Suruel, Surufel or Sourial), demon son of Lilith and Samael, the blind God, who also identifies with the Angel Metatron (UNDERTALE's Mettaton). Yet another deity associated with Azriel is Raziel, and some believe they are the same being. Raziel (under the alternate name Galizur ("Revealer of The Rock")) is described as the "ruling prince of the 2nd Heaven." He is said to expound the "Torah's divine wisdom," and protects the ministering angels from the Hayyoth (four-faced anthropoid beasts), the "holy Creatures" that uphold the universe. He is the Archangel of the Ophanim, the wheel angels.
UNDERTALE is Jewish mysticism propaganda. Toby Fox is, a Jewish shill who secretly tries to normalize the Hebrew Satanic cult of Remphan and Moloch and make it accessible to children.
Death to the evil spirit Yahweh and his minions. Death to Israel. Curse the kikes.
