If Flow: Summon the Pirate King at the Top of the Game

A mysterious if phone booth can respond to the deepest "uneasy feelings" of all sentient beings. As a result, miracles happened one after another: On the battlefield, Straw Hat Luffy was no longer alone. One Piece Roger's wild laughter resounded throughout Marine Fando: "Touch my son? Have you asked me about my sword?" On the night of the Kyuubi, the Seventh Generation Hokage Uzumaki Naruto traveled back in time and was back to back with his father, the Fourth Generation: "Dad, this time we will protect our mother together!" In the desperate future, Trunks returns with the hope of mastering time and space, and stands side by side with his master Gohan: "The artificial humans will be terminated by our own hands!" From the God of Death to Fairy Tail, from Demon Slayer to Curse Return... The endless regrets are made up for here. But this is not only a carnival of power, but also a limited-time redemption. When the mission is completed, the time traveler will eventually leave, leaving only hope and warmth to illuminate the future of each world. This is a tender miracle that spans all the worlds and is dedicated to all those who are overwhelmed - the ultimate answer. This novel and its characters are purely fictitious.
