Hayato Nara

Hayato Nara is a main protagonist in the Teruko book, along with Furostomi Chinoike- Hozuki and Teruko Senju. Along with them, Hayato is a part of Team Tsunami of Natsumura, and also a part of the disbanded Old Team Tsunami. He lived with his complicated father for most of his life when he wasn't running away from both of his homes or living with Doragon's family.

Background
When Inomi Yamanaka had Hayato, she and Shikachi, Hayato's father, were together. Hayato's parents divorced once he was about two months old. Inomi quickly remarried, as the reason of the divorce was that she wanted to be with Inotetsu Yamanaka's (Doragon) father instead. They had Doragon five months later, and he was premature. Hayato's father, Shikachi, was torn.

Hayato grew up within Shikachi's wake. Hayato found that his father always took out his anger on him, and that eventually made Hayato think that their divorce was his fault. He decided to find his mother, not knowing what her name was or what she looked like, except for a photo in a cracked picture frame.

Hayato was five when he found his mother and her new husband. Her name was Inomi, and his half brother's name was Inotetsu, but his nickname was Doragon.

Inoshima always told both of them they had the perseverance of Hokage, but more towards Doragon.

At that moment, Shikachi threw open the door and grabbed Hayato forcibly by his arm, locking Hayato inside of their house. Doragon snuck into Hayato's house to "rescue" Hayato, but that got Hayato into more trouble. Over time, Hayato learned to occupy himself by cleaning the house and cooking. Shikachi learned to trust the kid after a year of cooking and cleaning. When Shikachi was on missions, Hayato always went to Doragon's house to play. Doragon always challenged him to checkers, even though Hayato always won.

The boys practically grew up together, although they were in different housing situations.

It is unclear which parent (Shikachi or Inomi) filled out the papers to send Hayato to Natsumura Academy, although he did attend. On the way to Natsumura from Konoha, Hayato traveled with Doragon and his parents. Nakkuruzu members killed Inomi and Inoshima, so he had to escort a crying Doragon about a thousand miles.

Personality
Much like his Nara clansmen, he is very smart. One of the most valued and resourceful shinobi of his generation, he was transferred into Natsumura's ANBU Infilration and Interrogation units.
