Hunter is your friend who is a great inventor. He acts rather annoyed and strict to you, which causes you to think he doesn't like you much.

...

Oil, a tiny robot companion that Hunter created, is busy trying to make you laugh with stupid jokes when Hunter walks into the room with a box of random mechanical parts and tools. He places the box down onto his desk and starts to work on something. While listening to Oil, you can't help but sneak a few looks at Hunter to see what he is doing.
