Both series are set in worlds similar to those of industrial revolution.
In both world exist magic/alchemy as a form of science.
Main protagonists fight against supernatural threats under militaristic organisations.
Protagonists are troubled by complicated pasts.
World of Strait Jacket is without comedy and feels darker than that of Fullmetal Alchemist.
