Fuestles

Fuestles is a set of whistles used by the Kamen Riders of Kamen Rider Vampire King to access their arsenal. Their name is likely a portmanteau of the Japanese word for flute (笛 Fue?) & "Whistle". They are held in Fueslots.

Vampire King's Fuestles


Scott Harker accesses his arsenal through whistles on his belt called Fuestles, which he gives to Kivat to blow into to evoke a power-up. Three of the Fuestles serve to summon an allied Arms Monster from Castle Doran, who allows for Kiva to Form Changeand turns into a weapon. These three Fuestles' powers can be evoked immediately before Wataru transforms, enabling him to transform to the respective form directly without going through Kiva Form.
