Granbell Scarlet (グランベル・スカーレット, Guranberu Sukāretto) is a fan-made Touhou Project character from Futaba Channel, which simply originated from the name 'Flan' (フラン) being mistyped as 'Gran' (グラン) around February 23, 2013.

On February 23, 2013 at 5:33am, an anonymous user had posted “Remilia and Gran aren't sisters” (レミリアとグランは姉妹仲悪くないよね) with the aforementioned typo. By 3:57pm, somebody humorously wrote a description for 'Gran' in the style of Hieda no Akyuu's Gensokyo Chronicles from the print works, then the users started generating a design for 'Gran' that would obviously be based on Flandre Scarlet.

Granbell is a vampire that looks similar to Flandre, but with twintails, two ribbons on her mob cap, a dark red vest with a large ribbon, and flame wings. She could be found wandering across Gensōkyō, though nobody has found out why. While she turns out to be very sociable with humans, she is a vampire regardless, though she hasn't ever been seen sucking human blood.

Her main ability is to 'create anything' by putting her hands on the target object, which allows her to turn said object into something completely different. It can be said that she's considerably more skilled at alchemy, compared to Patchouli, and it's implied that the reason she wanders around Gensōkyō is to gather ingredients that would be useful in alchemy. In other words, her main ability would be 'alchemy' instead.

• I'd translate her name as Granvelle Scarlet, but her English name was already decided. I assume that the romanization is probably based on the number of Granbell Hotels in Japan.
