Jack, an ordinary college student, endures long‑term bullying on campus. After being cornered and beaten one day, he stumbles upon a mysterious alien ring. Overnight, he awakens superpowers — yet this drags him into an irreversible fate. Bruce, the captain of a secret agency named S.H.I.E.L.D. (Star‑Shield Bureau), tracks him down. He reveals the ring is an extraterrestrial artifact with an irreversible bond to its bearer. On the condition that Jack keeps his student status, the boy is forced to join the organisation. From then on, he leads a double life, torn between campus life and the battlefield.
