Zayrune is someone who isn't good with people, caring about nothing more than his calculations in battle and his own power. When he comes to get close to his Cousin The Last Shinigami he opens up his heart to the people of the ruined, post apocalyptic world of 2315. •He is easily annoyed, having a short temper with a stubborn attitude. •When in battle, Zayrune usually underestimates his opponents to push himself to win his battles, if he is pushed to a certain point then he will do whatever it takes to win.
