Hayato Shin

Hayato Shin is part of the Rookie 10 (Canon Name: "Rookie 9"; changed for this character), and was placed in Team Kakashi due to lack of space in the Genin/Team Correspondence roster. Currently, he is a Tokubetsu Jōnin of Konohagakure, and is tasked with the duty of body guarding Team 7; which now consists of Sai, Sakura Haruno, and Naruto Uzumaki. He is labled as crazy and annoying by others, but seems to make good friends with Ino Yamanaka and Hinata Hyūga.

Background
Hayato never got to know his parents, however, this didn't stop him from succeeding as a ninja. Due to this, Naruto looked up to him in some sort - something which Hayato seems to dislike (due to the fact that he catches Naruto staring at him from time to time). Having been supported by the leaf village, he was sent to the Academy for ninja studies. At first, Hayato disliked the idea of being a ninja, especially since it involved a lot of risky and missions containing fear. Not having a choice, however, he stayed in the Academy, ignoring the offensive names other students threw at him (sissy, wuss, garbage). Hayato viewed this as the point in life which everyone once has/had to go through; a period in which every child goes through bullying. Because of this type of mindset, he wasn't offended at all. Eventually, he became one of the few rejects in the class; his only friend being Hinata Hyūga, whom she told her deepest darkest secret to - her love for Naruto. Ever since then, Hayato began to spy on Naruto. Surprisingly, he was never caught. With this said, Hayato knew a handful about Naruto, including the fact that he had a very big crush on Sakura. After telling Hinata this, she broke down into tears, but decided to keep her hopes up for him. Eventually, after a year of being in the Academy, he fell in love with the Ninjutsu classes. In turn, he studied hard and developed his own basic (at the time) Ninja Art, which was based off his favorite book, "The Adventures of Love"; he brought his made-up character to life with his made-up techniques. Due to this, he was often referred to as a "larper" or "a kitty". His techniques involved cat-like transformations, explosive combat, and close-ranged fighting gear. It wasn't until he beat Sasuke Uchiha in a small ninjutsu skirmish that people began to view his techniques as rather potent (atleast in the academy). This seemed to impress the proctors, especially because of his young age. Eventually, he gained the respect of Shikamaru Nara, who seemed to like his creativity.

Personality
Many seemed to think that Hayato had a rather nasty personality - which to them, showcased stuck-upness and self pride. Only Hinata new his true side; funny, wild, and rather loud. Hayato also wasn't really shy, he did, however, have somewhat of a soft spot when it came to being repremended by his teachers in front of the class. Hayato was a fan of romantic books and romantic fan-fictions based off his favorite series of books (who's chapters come out weekly in convenience stands). Because of this, he seemed to get along with Ino Yamanaka. Like Ino, he has a tendancy of spoiling every chapter for Sakura Haruno, earning him a punch. He does, however, hit her back, starting short fights which end up being broken up. Hayato is rather comical and enjoys saying things that make no sense what so ever in order to draw attention. Hinata and Ino find it hilarious, where as people like Sasuke and Shino find it down-right stupid and annoying. Whenever tasked with something, Hayato seems to take it to the next level, as shown when he dressed up like a girl when stalking Naruto for Hinata. His "code-name" while undercover was "Yukari-chan" and he often talked with falsetto to sound rather girly and innocent.
