JoJo: Golden Spirit — Ermes Costello (SSR) Guide

Ermes Costello is a confirmed SSR unit from Part 6 in JoJo: Golden Spirit (fighting style not yet revealed). Here’s who she is and whether she’s worth chasing at launch.
⚠️ Pre-launch note: Ermes’s exact skills, stats and star-up path aren’t public until the August 13 launch. This page covers the confirmed facts (rarity, Part, style) and her source material — we add the full kit on day one.
Who is Ermes Costello?
Ermes is a fierce, fiercely loyal inmate who joins Jolyne Cujoh early in Part 6: Stone Ocean. She is driven by a single purpose: revenge for her murdered older sister, and she deliberately got herself locked up to track the killer down. Tough, blunt and protective of her friends, she becomes one of Jolyne’s steadiest allies inside the prison.
Stand: Kiss
Ermes wields Kiss, a Stand that applies sticker-like tags to whatever it touches, each one creating a perfect duplicate of the tagged object — or even a double of a whole person. The trick lies in what happens next: when the sticker is peeled away, the copy snaps violently back into the original, and any damage the duplicate took is delivered to the source at double force. It turns a single well-placed sticker into a devastating delayed strike.

Should you reroll for Ermes Costello?
An SSR with a high-damage gimmick is an appealing opening pull, but Golden Spirit rewards a balanced team over any single character. If Ermes appeals to you, a light reroll is reasonable — see the reroll guide and check the confirmed roster on the tier list.
