Sekai no genwa

In the year 2018, Magic has thrived as way to protect humans from war beasts known as Genwas(lit.meaning manifested). Over the last few years humanity had advanced the magic 2x times more powerful by experimenting on the genwa, forming a system called Genwa tamers( special contracted magic users who wield similar strength to that of the genwa). Now resting on Kasumi-jima(a fictional man-made island connected by a sea bridge to mainland Japan), the Tahara brotherhood train all kinds of students willing to learn magic. However their so called good intentions hangs in the balance when the J.IG.A (The Japanese Imperial Genwa Army) and Stationary Police (S.P.) interfere with the brotherhood's true plans.

Naohiro Matsuki and his childhood friend Kouga Masamune have lived their days in the Tahara brotherhood research facility(acts as an orphanage and a prison) and are about to be taken where they receive the treatment of becoming a genwa tamer. But just when it becomes their turn to take the exam, something unknown to both Nao and Kouga presents itself to the brotherhood, resulting in many deaths and allowing the JIGA and SP to usurper the Tahara brotherhood.

Resulting in a new world order that was to fight for humanity's sake in winning against the Genwas.
