As a wild youth, elementary school student Shouya Ishida sought to beat boredom in the cruelest ways. When the deaf Shouko Nishimiya transfers into his class, Shouya and the rest of his class thoughtlessly bully her for fun. However, when her mother notifies the school, he is singled out and blamed for everything done to her. With Shouko transferring out of the school, Shouya is left at the mercy of his classmates. He is heartlessly ostracized all throughout elementary and middle school, while teachers turn a blind eye.

Sincerely regretting his past actions, he sets out on a journey of redemption: to meet Shouko once more and make amends. Koe no Katachi tells the heartwarming tale of Shouya's reunion with Shouko and his honest attempts to redeem himself, all while being continually haunted by the shadows of his past.

Saenome are tasked with sealing spirits that possess objects and pose a threat to society. Known as tsukumogami, these spirits are generally non-violent, and saenome normally seal them after a simple verbal exchange. Traumatized by a previous deadly encounter with a malevolent spirit, Hyouma Kunato refuses to use peaceful methods and gets into physical confrontations with all tsukumogami that cross paths with him. Deeming this behavior unacceptable for a future clan leader, Hyouma's grandfather, Zouhei, proposes that he starts living with Botan Nagatsuki, a young woman whose family is composed of six tsukumogami—lest he be excommunicated. Determined to track down the spirit that took everything from him, Hyouma reluctantly accepts Zouhei's proposal. As unknown groups of evil spirits begin to jeopardize the balance between worlds, the young man must gain the trust of Botan and overcome his hatred for her mysterious family.

Although Hyouma Kunato has begun to feel comfortable around Botan Nagatsuki and her family of tsukumogami—objects possessed by spirits called marebito—he has not forgotten about his main goal in life: revenge. Unbeknownst to Hyouma, while he is training in Kyoto under the supervision of the Kadomori family, the Bureau of Traditional Music, a group of three musical instrument tsukumogami, begins to enact its plan. The trio questions Botan's family about their intentions regarding Hyouma's presence near the person embodying the frontier between the human and marebito worlds. Soon after, the paper umbrella tsukumogami that Hyouma had been pursuing for years suddenly reappears and abducts Botan along with her university friends. Rushing to save the one he swore to protect, Hyouma might have to change his priorities if he wants to keep his promise to Botan.

Japan, 2019, just before the dawn of a new era. Suddenly, a rift to another dimension appears in the sky, revealing an alternative world "Shinkoku Nippon," with the sky and the earth upside down.

The military invades the real Japan with giant humanoid robots called "Garann" and their gas weapons "Genmu", rendering our modern weapons ineffective. "Shinkoku Nippon" instantly seizes the government and achieves de facto conquest of Japan. The new era, "Reiwa," has now arrived for Japan. (Source: MAL News)
