Katsuragi

The second-of-command of the Black Hawks. He acts very motherly around his teammates. He is actually Landkarte of the Seven Ghosts. His body contained a defect, and this defect corrupted Landkarte and turned him into the "black shadow". Manipulating both the Pope and the Emperor, he was directly responsible for the Raggs War, and later betrayed the other Ghosts for Verloren; killing them all with the sole exception of Karu (Ea), who escaped. He later infiltrated the Barsburg Armed Forces, and assumed the identity of one of Admiral Ogi's subordinates, the real Katsuragi, whom he found dying on the battlefield. His real name is unknown. He later became one of Ayanami's subordinates, but then he betrayed the Black Hawks, as he believed Ayanami had become too attached to his (Ayanami's) subordinates. He engaged Frau and Teito, but this proved his downfall, and he was purified by Teito. He ascended to Heaven after the Chief of Heaven forgave him, after giving his Cursed Ticket to Teito.
