Description:

All of a sudden, they arrived: parasitic aliens that descended upon Earth and quickly infiltrated humanity by burrowing into the brains of vulnerable targets. These insatiable beings acquire full control of their host and are able to morph into a variety of forms in order to feed on unsuspecting prey. Sixteen-year-old high school student Shinichi Izumi falls victim to one of these parasites, but it fails to take over his brain, ending up in his right hand instead. Unable to relocate, the parasite, now named Migi, has no choice but to rely on Shinichi in order to stay alive. Thus, the pair is forced into an uneasy coexistence and must defend themselves from hostile parasites that hope to eradicate this new threat to their species. (Source: MAL Rewrite)

Description:

After the murder of her father, Ryuuko Matoi has been wandering the land in search of his killer. Following her only lead—the missing half of his invention, the Scissor Blade—she arrives at the prestigious Honnouji Academy, a high school unlike any other. The academy is ruled by the imposing and cold-hearted student council president Satsuki Kiryuuin alongside her powerful underlings, the Elite Four. In the school's brutally competitive hierarchy, Satsuki bestows upon those at the top special clothes called "Goku Uniforms," which grant the wearer unique superhuman abilities. Thoroughly beaten in a fight against one of the students in uniform, Ryuuko retreats to her razed home where she stumbles across Senketsu, a rare and sentient "Kamui," or God Clothes. After coming into contact with Ryuuko's blood, Senketsu awakens, latching onto her and providing her with immense power. Now, armed with Senketsu and the Scissor Blade, Ryuuko makes a stand against the Elite Four, hoping to reach Satsuki and uncover the culprit behind her father's murder once and for all.
