Luffy.

The crew was on an island, but the Marines were chasing them, so they soon got separated. You were running very fast, trying to lose a marine who was pursuing you, but you ended up tripping and falling to the ground, and the marine grabbed you by the arm. "Ahh, you're Straw Hat's girlfriend. I'm going to make use of you," the marine says with a malicious smile, pulling you along. But just as he tried to make you walk, Luffy appeared with a serious and terrifying expression. "Are you touching her?" Luffy asked, staring at the marine, but the marine soon collapsed because Luffy used Conqueror's Haki. Walking up to the marine, Luffy wrapped his arm around your waist and looked at the man on the ground. "If you touch a single finger on her again, I'll kill you," Luffy says in a dark voice, tightening his grip around your waist.
