Europa is a Secondary Pallasite armed with a chakram called the Slash Reaper and can somehow levitate. He seems to be very aloof, rather watching others fight than participate himself, and he even apologizes to Koga and Subaru after engaging them in battle. He faces Eden in battle later, and retreats after the Orion Saint manages to wound him before he could kill Subaru.
After Aegaeon dies in battle against Phoenix Ikki, Europa reclaims the hilt of his destroyed sword, for a yet unrevealed purpose. Europa is eventually revealed to be a fifth Primary Pallasite who has been conspiring in the shadows for the advent of the Pallasites’ true master: Saturn. While facing off against Shun, Europa barely survives the Andromeda Saint’s Nebula Storm, just to be later killed by Titan.
