The Beelzeboss League
Jin Kisaragi is the last of Poseidon's main commanders. He is Ragna The Bloodedge's brother and Noel Vermilion's higher ranked commander. He has joined Zeus's fake group The Beelzeboss League just so he can kill Ragna as well as Fairy Leviathan for deserting Poseidon, however it won't just be out of Fairy betraying his master, but also out of jealousy of how they are both almost alike, yet stand apart different that Ragna might take her over him. Jin hates that and wants to make sure Fairy doesn't get to spend anytime with his brother, ever! And when he is finished Jin under the mental influence of his sword Yukianesa will enjoy carving Ragnas body into pieces with it.
Jin and his brother returned in the next crossover story.
