'Ulu Nawahine

 'Ulu Konane Nawahine is from Hau'oli City on Melemele Island in the Alola region. He's the brother of Mallow Nawahine and the son of Abe Nawahine.

Background
When 'Ulu was 13, his mother died from heart failure. He did what he could to help with the family and keep up the spirits of his sister, Mallow, and his father, Abe. They all pulled through and stayed positive.

When 'Ulu turned 18, he moved out and got his own apartment. Some time after this, Mallow approached him with a dilemma she was facing. She asked him if they could help out one of her friends, referring to Lana. Lana was going through some situations at home and Mallow wanted to move in with him and bring along Lana. 'Ulu accepted and allowed them to live there. He's usually not home and has no problem with helping out. By the time the series starts, it had been 7 years that the three have been living there.

Present
'Ulu hasn't debuted yet. He was mentioned by Mallow in Episode 31 when she was telling the Mokusetsu about herself. She mentioned about how he allowed herself and Lana to room with him in his apartment, since Lana wanted to get away from her parents.
