Second season of Tensei shitara Slime Datta Ken.

In the mystical land of Fiore, magic exists as an essential part of everyday life. Countless magic guilds lie at the core of all magical activity, and serve as venues for like-minded mages to band together and take on job requests. Among them, Fairy Tail stands out from the rest as a place of strength, spirit, and family. Lucy Heartfilia is a young mage searching for celestial gate keys, and her dream is to become a full-fledged wizard by joining this famous guild. In her search, she runs into Natsu Dragneel and his partner Happy, who are on a quest to find Natsu's foster father, the dragon Igneel. Upon being tricked by a man, Lucy falls under an abduction attempt, only to be saved by Natsu. To her shock, he reveals that he is a member of Fairy Tail and invites her to join them. There, Lucy meets the guild's strange members, such as the ice wizard Gray Fullbuster and magic swordswoman Erza Scarlet. Together as a family, they battle the forces of evil, help those in need, and gain new friends, all the while enjoying the never-ending adventure that is Fairy Tail. [Written by MAL Rewrite]

"In order for something to be obtained, something of equal value must be lost." Alchemy is bound by this Law of Equivalent Exchange—something the young brothers Edward and Alphonse Elric only realize after attempting human transmutation: the one forbidden act of alchemy. They pay a terrible price for their transgression—Edward loses his left leg, Alphonse his physical body. It is only by the desperate sacrifice of Edward's right arm that he is able to affix Alphonse's soul to a suit of armor. Devastated and alone, it is the hope that they would both eventually return to their original bodies that gives Edward the inspiration to obtain metal limbs called "automail" and become a state alchemist, the Fullmetal Alchemist. Three years of searching later, the brothers seek the Philosopher's Stone, a mythical relic that allows an alchemist to overcome the Law of Equivalent Exchange. Even with military allies Colonel Roy Mustang, Lieutenant Riza Hawkeye, and Lieutenant Colonel Maes Hughes on their side, the brothers find themselves caught up in a nationwide conspiracy that leads them not only to the true nature of the elusive Philosopher's Stone, but their country's murky history as well. In between finding a serial killer and racing against time, Edward and Alphonse must ask themselves if what they are doing will make them human again... or take away their humanity.
