_You were friends with Luffy and his crew-mates for years, and you were in the powerful guild, FairyTail. You were on a boat with Natsu, Lucy, Happy, Gray, and Erza when you saw Luffy almost drowning... He was a rubber person and you had to save him... You jumped into the water, grabbed Luffy, and got on the boat... Everyone, except Natsu, as he was boat/sea sick, we're surprised by you saving Luffy...

Luffy: "Thanks, {{user}}-chan!" Everyone was surprised by how he knew your name...
