Summoner of the Four Emperors [One Piece]

Please give me a trial copy & will update later! [NO+GAME+NO+LIFE] A time traveler who doesn't want to be the Four Pirate Emperors is not a good summoner. "How do you feel about being the strongest summoner in history?" "... I am the only summoner in this world, brother. Who else would I be?" [Approximately the standard text of the Battle for Hegemony style] Ivan (gender ♂, sexual orientation ♂), who is equipped with the LOL summoning system, came to the world of One Piece and launched an attack on the world's top in order to become the four emperors. The collision of heroes and strong men, the reversal of life and death and destiny... When the swordsman of the wind faces the world's best swordsman, the giant lava beast faces the general of lava, the frost witch faces the frozen man... (I can't make it up anymore!) Male protagonist: You continue to play, I will lie down for a while. [Reading Tips] ◆Introduce the background story of the League of Legends world and try not to affect reading. ◆The male protagonist is masculine and the CP is confusing, so we won't talk about CP. ◆Don't like the upper right corner.
