Funeral Service: Am I Rumored to Be the Strongest Hero?

"You are an ordinary person, your life is as ordinary as water, but before you die, you decide to go crazy..." "You bought all the 'fun at the funeral' services and planned to play a little joke on your family after you died." "... I have to admit that they did a pretty good job. Not only your family, but even everyone believes that you were once a Kamen Rider, Ultraman, Superman or something else." "Why do you know this?" "Because hundreds of years later, when faced with the invasion of enemies from another world, you were used as the ultimate weapon, and the strongest hero in human history was resurrected."
