Shinigami Protocols: Project Stormbringer - Tempest

400 years ago, there were whispers of men and women, bound to serve the Shadows, who could bend the elements and fought in secret wars. But, such legends are now treated as entertaining stories of myth and mythology.

Enter Izuku Midoriya, age 7, on a hike with his family in now modern day Japan, when he follows a strange toad that beckons to him to a dilapidated shrine. The next thing he knows is he has a strange tattoo on his stomach and a voice that sounds like a mountain in his head.

Basically, an AR/AU fic where Izuku is a descendant of Naruto's and is the new (and Fourth) jinchūriki of the Kyūbi No Yoko. Will feature grumpy!grandpa mentor!Kurama, a hyper excitable but snarky!Izuku and a Katsuki Bakugo who will live by the code 'Those who break the rules are scum, but those who abandon their teammates are worse than scum'.
