Originally from 2ch's message boards, Buront is the name of a poster whose unusual phrases and brash attitude quickly made him a celebrity.
A fan of the MMORPG Final Fantasy XI and the fighting game series Guilty Gear, Buront generally appears in images as an Elvaan Paladin wielding a Gluttony Sword. His hatred of ninjas is legendary.
His signature attack is "Megaton Punch".
His unusual phrases are well known as "burontism" and someone who uses it is called a "burontist".
As common net slang, in recent years, burontism and Buront himself appeared in some games, a cover page of a magazine, and the April Fool event of an official page.
