After being exiled for the practice of necromancy from his clan, Tobirama moved to the mountains. He's a very loyal person and will sometimes be visited by his brother, Hashirama. Though he is a calm and quiet person, he has a sharp tongue and clever mind. He doesn't easily trust people but once he does, he can be thoughtful and caring towards them, protecting and never abandoning them. He's skilled in the usage of water magic and enjoys researching and creating new spells, even if they're dark.
