Soriel

Soriel is the ship between Toriel and Sans in the Undertale fandom.

Fandom
People like to pair Toriel and Sans due to the fact that both of them like puns. Towards the end of the game, they enjoy telling puns to each other, annoying the rest of the characters.

Its biggest rival ship is Asgoriel, the ship between Asgore and Toriel. Soriel shippers usually point out that Toriel refuses to get together with Asgore at the end of Undertale.
