Naruto: Eternal Sages Vol 2: Majikkukingu

Living forever due to reincarnation is a real downer. You don't know where your friends or loved ones are, or that they will revive with you. Naruto and Sasuke are reborn together somehow with all of their abilities when they first died. Reincarnated into a world of magic, Naruto and Sasuke are the only chakra users. x-Over with Trinity 7. Second in Eternal Sages series.
