Rumor has it that if a young girl strikes a bargain with a white fairy, it will grant any wish her heart desires. However, in exchange, she will become a magical girl and must put her life on the line to slay fearsome and ferocious witches. Iroha Tamaki, a kind-hearted middle schooler from Takarazaki City, is living proof that these rumors are true. Armed with a magical crossbow and the ability to heal injuries, Iroha seeks out the labyrinths where witches hide and defeats them before they can prey on humans. Yet Iroha has no memory of her wish, and even Kyuubey, the white fairy himself, seems to have no idea what Iroha requested of him. One day, Iroha hears rumors of a city where "magical girls can be saved," and finds herself on a sunset train to Kamihama City. Unfortunately, she discovers that the witches in Kamihama are far more powerful than usual. After veteran magical girl Yachiyo Nanami is forced to save her, Iroha vows to never return. But when a chance encounter with a tiny Kyuubey seems to trigger distant memories, Iroha is compelled to investigate the mysterious city despite the danger. [Written by MAL Rewrite]

Fifteen years have passed since the war between humans and demons began. Dissatisfied with their slow advance into the Demon Realm, the Hero abandons his companions to quickly forge ahead towards the Demon Queen's castle. Upon his arrival at the royal abode, the Hero makes a startling discovery: not only is the Demon Queen a woman of unparalleled beauty, but she also seeks the Hero's help. Confused by this unexpected turn of events, the Hero refuses to ally himself with his enemy, claiming that the war the demons have waged is tearing the Southern Nations apart. However, the Demon Queen rebuts, arguing that the war has not only united humanity but has also brought them wealth and prosperity, providing evidence to support her claims. Furthermore, she explains that if the war were to end, the supplies sent by the Central Nations in aid to the Southern Nations would cease, leaving hundreds of thousands to starve. Fortunately, she offers the Hero a way to end the war while bringing hope not only to the Southern Nations, but also to the rest of the world, though she will need his assistance to make this a reality. Finally convinced, the Hero agrees to join his now former enemy in her quest. Vowing to stay together through sickness and health, they set off for the human world. [Written by MAL Rewrite]

The second season of Morita-san wa Mukuchi that directly follows the first.

Morita Mayu, a high school girl. She is extremely reticent and her silence and habit of looking at people's eyes straightly sometimes cause misunderstanding. The reason behind it is not because she doesn’t like to talk nor because she has nothing to say. The reason she rarely speaks is due to the fact she thinks too much before speaking, thus losing the timing to speak altogether. But she lives a happy school life with her classmates.
