Rohan Kishibe is a character introduced in Part IV: Diamond is Unbreakable.
Being a successful mangaka by profession, elements of his personality and experiences seem likely as self-inserts by Hirohiko Araki. The name Rohan Kishibe is also an approximate anagram of "Hirohiko Araki", sharing enough letters to spell "ARKI HIHO", unless completing the anagram by duplicating the missing letters with O, R, A, I and K.
This came out great, all the measurements were perfect including the sleeve/pant length, the pants sit right above my hip, the jacket fits snugly over the sweater, and the shoulderpads are a very nice touch. My only complaint is that the polyester material is a little thin, so the zipper and pads are visible through the shirt and I'll have to wear nude-colored underwear to keep it from showing through the pants. Other than that, though, it's amazing quality for a pre-made cosplay, and I'm very excited to wear it at the convention. Thank you, and I'll definitely be recommending this service to my friends.
