Team Natsu's Formation

Team Natsu's Formation is an event during the Daybreak arc where Natsu Dragneel, Lucy Heartfilia and Happy officially decide to form a team with one another.

Prologue
Lucy finds an apartment to live in within Magnolia Town’s shopping center and while enjoying her new place, she receives an unwelcomed visit from Natsu and Happy. While both are there, Lucy explains about Celestial Spirits and demonstrates how to make a contract with one, in turn making a new contact with Nikora, also called Plue.

Team Formation
After being contracted, Plue suddenly does various unusual motions with his body that Lucy cannot figure out. However, Natsu can. Natsu starts talking to Plue about Lucy’s strengths and decides that she is weird, but a good person nonetheless. He finally exclaims that he agrees with Plue’s (unspoken) idea and suggests to Lucy and Happy that they form a new team together. Happy quickly understands what Natsu is saying and explains to Lucy that in guilds, people who form teams usually form one with people they easily get along with, and that usually it makes difficult quests much easier for some. Lucy cheerfully agrees with the idea and thus, Team Natsu is formed.

Aftermath
Natsu quickly suggests that they go complete a job and pulls out a Job Request flyer, one that asks to retrieve a book from Duke Everlue’s mansion, with a reward of 200,000. Lucy then looks at the extra information and discovers that the owner of the mansion is a perverted womanizer who is seeking blonde-haired maids; in other words. Natsu says that they should make Lucy into a maid since she’s blonde and Lucy is shocked that they tricked her into the Job. Still, this does not stop them from going forth to complete their Job.

At the Fairy Tail guild, Team Shadow Gear notices that the Duke Everlue job was taken and learn that Natsu took it for himself and Lucy. Makarov says that it was best that Levy’s team didn’t take it because the reward, from what he recently learned, was raised ten times higher to 2 million.
