Furfur

Furfur (フルフル) is a demon of Hell and Zepar's twin. Furfur always appears in unison with Zepar when summoned, and has the power to cultivate emotions. Furfur can also grant an inexhaustible offensive power to those who contract them. Furfur's gender is ambiguous, though it is stated that Furfur's gender is the opposite of Zepar's.

Appearance
Furfur is ambiguously gendered character with shoulder-length copper hair with trimmed bangs as well as bright cyan eyes. Furfur wears a flashy yellow and white outfit with maroon accents and complete with a green hat.

Dawn of the Golden Witch
The first time Furfur and Zepar are seen is when Shannon and George challenge Kanon and Jessica for the love gold butterfly brooch which can grant love to one of the two couples. Furfur and Zepar call for Beatrice the original owner of the brooch to supervise the challenge. Noticing that there are two Beatrices, the twins make jokes about it, and then allow "chick Beatrice" to take part at the challenge to win Battler's heart.

The first part of the love trial is solved with Beatrice's victory and the two demons let happily join Battler to the challenge by Beatrice's side. After the trial is over Zepar and Furfur give the brooch to the winning couple and bless their young love.

Requiem of the Golden Witch
In Requiem, Furfur and Zepar appear as two actors on the stage of the show presented by Clair Vaux Bernardus. They mainly comment on what Clair has shown and interview all the characters of the story one-by-one. As previously hinted in Dawn, it is confirmed by Will that Furfur and Zepar were added to the previous game and to Requiem to enlarge the mystery about Beatrice's gender, so in a way the two demons are also connected to Beatrice.

Ougon Musou Kyoku
Both Furfur and Zepar also appear in Ougon Musou Kyoku, where they introduce every match, and they guide the player through the main menu. They can be seen also in the opening video.

Trivia

 * The character Zepfur from When the Game Ends appears to be loosely based on Zepar and Furfur.
