Straight Jacket [Manga]

Strait Jacket is set an alternate history where magic was proven to exist in the year 1899. The use of sorcery spread throughout all facets of society and changed the social and technological development of the world. The location is Tristan, an urban metropolis that appears to be an amalgamation at the turn of the 20th century Tokyo, San Francisco, and Victorian era London. The technology of this world is heavily steampunk-inspired, with most of it being clockwork and steam driven, and although electricity has been discovered, electronic devices are still in their infancy stages. Steam powered factories are prevalent and their massive chimneys dominate the skyline of Tristan, and many of the cast-iron and glass buildings are styled in the form of gothic architecture. The public fashion seems to be very much like that of Victorian era London. Although the internal combustion engine has also been discovered and automobiles exist, vehicles are very rare and those that exist are reminiscent of 1930s models. The primary means of transportation for the public still remain steam trains, trams, zeppelins, and horse drawn carriages.
Alongside this technology and science exists magic, which has been proven possible in public demonstrations by Dr. George Greco. Although the use of magic is only possible for a few talented individuals, it is very dangerous and highly illegal. Due to an invisible contaminant called the “malediction”, or simply the “curse”, people who use magic too often are at risk in transforming into “Demons,” or horrific, malevolent abominations of nature that become immune to ordinary weapons. The Magic Administration Bureau, also known as the Sorcery Management Bureau, is set up in the attempt to safely explore the nature of magic, officially document it, attempt to provide rational scientific explanation for it, regulate its use and police those who use magic illegally. Magic, utilized in a safe sense by the Bureau, has been used as a viable energy source
