The Yo-kai Medallium bio states; "Grapenyan's aroma drives the ladies crazy and boy does this narcissistic Yo-kai know it!"
Grapenyan is a dark-purple Yokai with dull white muzzle and paw tips. It has big black eyes and a pale pink nose, while it's inner-ear coloring is purple. Around it's stomach is a purple band, while six light green orbs hanging from the neck. A dark green leaf and vine wraps around it's right ear. The flames of it's tails are green-yellow.
