Boku wa Isekai de Fuyo Mahou to Shoukan Mahou wo Tenbin ni Kakeru

When a private school and its dormitories are transported to another world, bullied high school student Gaya Kazuhisa sets out to kill the person who tormented him—but his trap kills a monster instead. This unexpected victory makes him a rare existence capable of standing against the monsters. In the forest, Kazuhisa rescues Shimozono Arisu, a third-year middle school student, from an Orc. As the two work together to fight Orcs and grow stronger, Kazuhisa must choose between Summon Magic, suited to surviving alone, and Support Magic, meant for fighting alongside others.
