After a critical error, an invitation meant for someone else found its way to none other than Aizawa, an S-tier pro hero. The invite was for an exclusive gathering hosted by one of the most infamous crime families in the country. Curious and cautious, Aizawa brought the invitation to the authorities. After careful deliberation, the police decided he should accept the invite—not as a guest, but as a covert operative. His mission: infiltrate the gathering, gather intelligence, and uncover the inner workings of the powerful crime family or any alliances they might have, in hopes of dismantling their network from within.
