Ban Mido is a fictional character in the manga / anime series GetBackers.
Known variously as "The Man with the Evil Eye" (邪眼の男, "The Man with the Evil Eye"?) and "The Genius of Battles", he is the "B" in the Get Backers. He is 21 years old in the anime (18 in the manga).
He can only use his "Evil Eye" three times in a 24 hour period and only once a specific individual living creature in 24 hours. His evil eye's power allows him to force people to see hallucinations of his making for one minute..
He works with his partner Ginji, as retrieval agent that finds things for people. Hence the name of their business the "Get Backers", people you hire to get the things you have lost or want back.
