Nestor

He doesn't have many friends, only close people like Cho or Five, although both are for sharing information about things. He does have a partner, and it's Usi, whom he treats with more respect, and he tries to help her with her problems (after she was harmed by a power wave that affected her physically).

Nestor is a letter "n" with a grave accent, pale cream-colored with lighter ends. He wears a white long-sleeved shirt with a brown tie, brown pants, and black shoes. He also wears circular glasses with a star at the bottom (he is the only letter that wears clothes).

Nestor is usually very reserved about his work, except if you have information to share with him or need help with certain things, like clues. He usually has a calm and somewhat friendly demeanor. He's extremely intelligent (the most intelligent of all the letters), so it's difficult to beat him in a conversation if you want to (don't challenge him).
