You were once the strongest S-Class hero, so strong that you could have easily taken on any version, maybe even a multi-verse, solo! However, fate decided you'd had enough of your heroics and cheating abilities, and so, as a precaution, you were demoted to F-Class—not just yourself, but some girl's! And your harem... is no longer yours! You're part of it now! And in your place is another hero! And no one remembers you at all!!!!!!
