At St. Mihailov Academy, strange things are happening. Not only did the dean disappear, leaving his daughter Tomo and adopted daughter Mafuyu alone, but girls in the nearby city are being killed by an unknown foe. However, the blades begin to fly when a Russian boy named Sasha arrives. He is a Qwaser, a person able to manipulate the elements after ingesting Soma, breast milk, and he’s not the only one. Soon Tomo and Mafuyu find themselves in the middle of a battle between two groups of Qwasers whose goal is to protect or steal the Theotokos of Tsarytsin. With more allies and enemies arriving, who will survive the assault?
Fate/Stay Night and Seikon no Qwaser are two series revolving around people that have the ability to control elements. They fight against similar people while trying to protect the humans of earth.
The first law of alchemy is that "one cannot gain something without giving something of equal value in return" - a rule that two souls dare to cross. When Edward and Alphonse Elric try to revive their dead mother, breaking the taboo of human transmutation in process, Ed loses his right arm and left leg while Al loses his entire body. After the tragedy, an alchemist named Roy Mustang visits them and tells Edward to become a state alchemist to find a way to recover what they have lost. Accompanied by Al, whose soul is now attached to a metal suit of armor, Ed is fitted with auto-mail parts in place of his lost limbs and becomes a state alchemist by the name of "Full Metal Alchemist." Together, they set forth on a journey to find the Philosopher's Stone - the one item that is rumored to have the power to restore them.
Akuto Sai enters the Constant Academy for Magick Arts hoping to become a high priest and change the world for the better. But when the school's oracle declares his future profession to be 'Demon Lord', he finds himself feared and hated by the entire student population. Now, instead of making comrades and studying for his exam, Akuto finds himself fighting off monsters, bullies, and well-meaning classmates in various states of undress. If navigating a magical high school as a transfer student wasn't difficult enough, Akuto now has to deal with a cute android ordered to observe him 24-hours a day, the precocious attention of the flying, invisible and naked Keena Soga and the advances of the school's most popular girl. Will he be able to overcome his fate, pass his classes, and mend his friendship with the violent Junko Hattori, or will he succumb to his demonic destiny?
