Marvel AU: Aura Resonance

Arlan Harper, a former overworked orphan reborn into a loving New York family in 1992, vows to cherish his second chance. With memories intact, he navigates childhood with genius wit. When he realizes this world hides superheroes and cosmic threats, Arlan combines his encyclopedic knowledge of manga training methods to unlock Nen—the only power system that works. Building a tech empire by day and a secret Nen-trained organization by night, he prepares to shield his family from the coming storm. Along the way, he befriends geniuses like Tony Stark, charms a certain chaos-magic witch, and discovers that strength lies not just in power… but in the bonds he’s sworn to protect.
