Seburo is a fictional small arms manufacturer commonly found in many of the works of manga artist Masamune Shirow.
Little is known about the company. Founded in October 2024, the company excelled in technology exploiting small caliber rounds packing the punch of much bigger caliber rounds. Seburo jumped into the forefront through reliable rapid fire and easily handled firearms.
Shirow frequently attributes the Seburo name to advanced, high-velocity, small-caliber weapons, similar in concept to firearms using 5.7x28mm SS190 and 4.6x30mm cartridges. Various models appear in works done by Shirow, usually identified by large SEBURO markings placed on either the gun's slide mechanism, body, or on other accessories like ammunition cans.
Going by the timelines of respective Shirow works, Seburo is noted or mentioned in Ghost in the Shell (set around the decade of 2030), Dominion (also set around the decade of 2020), and Appleseed (between 1988–2147).
