Using Sorcery and Cursed Techniques in the World of Naruto

I woke up in the world of Naruto! Around me is a group of black-robed fanatics, and a gray-haired man named Hidan is laughing wildly. It seems to be because I'm the second 'lucky one' to survive the divine selection ritual to gain the ability of [Immortality].

Akagi Shinsuke is speechless, and what's even more frustrating is that after the ritual, his body is full of chakra with no means to use it. This means that he will be a waste like Hidan, an immortal useless ninja! Luckily, the system changes his life! Can't learn ninjutsu? No problem! With this system, he can do anything!
