Strings of Mischief: Bound by the Blue Sea

After falling from the Bifrost, Loki encounters Error-Sans in the Void, where the latter had jumped to end his suffering. Both are transported to the One Piece universe and discovered by Garp, who assumes they are a couple.

Over two years under Garp's care, the two develop genuine feelings and eventually marry. When Garp introduces them to Ace and Luffy, Error bonds with them instantly. Though Loki remains indifferent toward children, he agrees to tolerate them for Error's sake. During their time with the bandits, Error utilizes an androgynous human disguise-a form Loki finds particularly captivating.
