I Became the Academy's Pink Airhead - Chapter 91

The protagonist is an accidental time traveler - he didn't wait, didn't guess, only dreamed, but ended up in history, which he didn't pay much attention to. He was just lucky with his lineage.Ryo is a new member of the Nara clan, from the Uzumaki lineage on his father's side, and it so happened that he was born not at the beginning of the known plot, but more than three decades and two world wars later. Now he has to figure out how to get out of this situation however he can.

【Follow the Ship】【I'm a Marine on My Own】【System】Ike thought he could convince Luffy to give up being a pirate, but instead, he ended up joining the Straw Hat crew. To make things even more awkward, he awakened the Justice Marine System—but luckily, he had a letter from Garp appointing him as a Private Marine. This meant that all the good deeds done by the Straw Hat Pirates would count as achievements for the Private Marines.Arlong: “So what if the Straw Hats defeated me? It’s not like I’m wanted.”Ike: “Huh? We’re a Private Marine crew. We just fly the Jolly Roger, but we’re not pirates. Why would we be wanted? One call, and the bounty is gone.”Crocodile: “The Straw Hats are in Alabasta. Why isn’t the Marine arresting them?”Marine officials: “Huh? They’re Private Marines, not pirates.”World Government: “The Straw Hat Pirates destroyed Enies Lobby! Arrest them immediately!”Ike: “Who said that? It was clearly that idiot Spandam who pressed the Golden Den Den Mushi, and the Buster Call wiped out Enies Lobby. Our Private Marines were just there to eliminate Spandam—the real culprit behind the destruction.”
