            Waking up in a strange bedroom in a dream world, teenager Haruto Tsukishiro finds a strange app on his phone. When he activates the program, an odd woman appears and tries to drag him to her realm. Luckily, a mysterious, white-haired girl severs their connection and helps him escape, revealing that the woman is a witch; however, their conversation is cut short. As Haruto enters the realm again, he meets an anthropomorphic, talking cat named Katsumi Kanzaki. While the witch's minions pursue them, the white-haired girl opens a door for them to escape.
After their ordeal, Haruto describes their savior—which only he can see—and Katsumi, the leading authority on dream world research, realizes that she must be "Lily," a being that resurfaces repeatedly across multiple dreamscapes. Hoping to leave the dream world through a blue door, they enter the witch's realm once again. Finding themselves in peril, Lily reveals the truth to Haruto: witches suffer from "Sleeping Beauty Syndrome," a coma-like sleep state induced by torment in their real world lives. Thus, they cannot wake until they are defeated in the dream world.
After finally defeating the witch and locating the blue door, Haruto and Katsumi say their farewells, promising to meet up in the real world. However, when Haruto exits through the door he awakens in the dream world bedroom once more. Seeking answers, Haruto and Katsumi try to uncover the mysteries of the witches, Lily, and Haruto's own inability to leave the dream world.

    7 Seeds
            Imagine this: you are living a normal day in your life. Maybe you are out with friends, eating your family's home-cooked meal or spending time with your girlfriend. When you next wake up, you are suddenly thrust into a strange, new world, surrounded by five strangers on a rapidly sinking boat in the middle of a storm.
For Natsu Iwashimizu, this is her new reality. Humanity has perished, and all that remains of the Japanese population are five groups of men and women who were chosen to be sent to the future in hopes of continuing mankind's existence. While every other person chosen has a useful talent such as martial arts, knowledge, or architecture, Natsu is a shy high school girl who cannot even raise her voice to shout. The new world is dangerous beyond imagination, and although Natsu seems to lack helpful skills, she must go with the others making their way to the "Seven Fuji" in order to survive.

    ACCA: 13-Territory Inspection Dept.
            ACCA—a national body of the kingdom of Dowa that provides public services to the citizens of the country—was established as part of the peace settlement between the king of Dowa and the 13 states of the country during a revolt. One hundred years later, Dowa is in a period of unprecedented peace, due in part to the ACCA system. However, rumors of a coup d'état start to surface. Jean Otus, the second-in-command of the inspection department of ACCA, is charged with inspecting all 13 state branches. What will he discover as he performs his audit?
Intriguing and mysterious, ACCA: 13-ku Kansatsu-ka is a politically-themed mystery that reveals a world of diverse cultures and lifestyles, with intricate connections between its characters, as the truth of the coup d'état slowly unfolds.

            In 1972, a popular student in Yomiyama North Middle School's class 3-3 named Misaki passed away during the school year. Since then, the town of Yomiyama has been shrouded by a fearful atmosphere, from the dark secrets hidden deep within.
Twenty-six years later, 15-year-old Kouichi Sakakibara transfers into class 3-3 of Yomiyama North and soon after discovers that a strange, gloomy mood seems to hang over all the students. He also finds himself drawn to the mysterious, eyepatch-wearing student Mei Misaki; however, the rest of the class and the teachers seem to treat her like she doesn't exist. Paying no heed to warnings from everyone including Mei herself, Kouichi begins to get closer not only to her, but also to the truth behind the gruesome phenomenon plaguing class 3-3 of Yomiyama North.
Another follows Kouichi, Mei, and their classmates as they are pulled into the enigma surrounding a series of inevitable, tragic events—but unraveling the horror of Yomiyama may just cost them the ultimate price.
