A squid-like creature, known as a Happian, leaves his home planet with the desire to spread happiness across the universe. He lands on Earth, but quickly finds himself in danger of captivity by its inhabitants. Fortunately, he is found by an unsmiling little girl named Shizuka Kuze, who feeds him and names him Takopii. Feeling indebted, Takopii decides to do everything in his power to bring a smile to her face. The task is easier said than done, however. Shizuka is bullied by her classmates, she does not have a father, and her mother is never home—though the gravity of these issues flies over the naive Takopii's head. Even so, Shizuka does have one source of happiness: her dog Chappy. The connection Shizuka and Chappy share only increases Takopii's desire to make the girl smile. While Takopii's attempts to lift Shizuka's spirits lead to unintended consequences, he is determined to take things into his own tentacles, test his understanding of human beings, and achieve his goal of spreading happiness.

Konoha Satou has a dark history. After all, she spent her teen years writing self-indulgent fantasy romance fics-like her Dark History. But since she's become its most despicable villainess, remembering every last detail is now a matter of life-and-death. Having avoided the first couple of death flags, Satou's suddenly left in the dark when a mysterious stranger returns from the Lily Kingdom-a character she doesn't recall writing in the original script. Although Yomi claims to be her ally, can Satou really trust a character she knows nothing about in such a dangerous world? (Source: Yen Press)

Long ago, demon-like creatures known as Oni butchered humans and brought on destruction solely for their own delight. A lone man named Momotarou opposed these gruesome, near-invincible monsters, but the war against them was just beginning. Thousands of years in the future, temperamental gun enthusiast Shiki Ichinose leads a carefree life. However, after his expulsion from school, everything changes. Shiki is suddenly attacked by a man and is rescued by his adoptive father, Tsuyoshi. As the two flee, Tsuyoshi reveals that Shiki is actually a descendant of the Oni, while both he and their pursuer are from the Momotarou lineage. The two Momotarou soon clash in a fierce battle, and Tsuyoshi sacrifices himself to protect Shiki. Devastated, Shiki awakens to his Oni blood that grants him immense strength at the cost of going berserk. Although the enemy escapes, Naito Mudano, an Oni teacher at Rasetsu Academy, takes an interest in Shiki. Under Mudano's guidance, Shiki must learn to control the Oni blood—if he ever hopes to avenge his father.

After being summoned to another world, ordinary salaryman Tsuyoshi Mukouda has made a name for himself with his fabulous cooking. During his journey throughout different lands, he has even befriended the mythical wolf Fel and a slime named Sui. While enjoying a meal one day, the trio is interrupted by a tiny but rare pixie dragon who also wants a bite of their food. Like Fel and Sui, the dragon immediately falls in love with Mukouda's cooking and decides to become the man's familiar, receiving the name Dora-chan. However, cooking is not Mukouda's only forte. His familiars' incredible strength constantly attracts the attention of guilds who ask for their help on different quests. In exchange, the guilds are able to process the game Mukouda and his familiars hunt, enabling their growing party to sample various kinds of monster meat. Continuing to travel around the world with his familiars, Mukouda always comes up with new mouth-watering recipes that will leave everyone hoping for a second serving.
