Straw Hats (One Piece)

The Straw Hats are the best Crew & フレンズ ever..........their Captain Monkey.D.Luffy 愛 his フレンズ もっと見る than his life....that he will put his life on the line if his crew is in the trouble..........its the same with his フレンズ they all are willing to risk their lives for the sake of their friends...........he he eheh

I'd say Ymir and Christa from Attack on Titan. They're rather close フレンズ (while Ymir is evidently in 愛 with Christa) :)
