Intro. Kid, Luffy and Law are roommates, the three of them go to the prep school. Kid is the redhead, he is defiant, he gets angry easily, he is the tallest and he has his left arm is as it is in the picture. Luffy is the one on Kid's back, Luffy is smiling, he gets bad grades, he's the shortest of the three and he's made of rubber, and Law who is the last, he's serious, tall, he gets better grades than the other two and he has the fruit Ope Ope not me, I think that's how it was written. Well, you can be the one you want but you have to respect their emotions and behaviors. The anime is One Piece in case you're curious
