The daily life of high school student Naoto Watari revolves around his little sister Suzushiro. As their parents passed away two years prior, the siblings have been passed from one relative to another, resulting in Naoto taking the most responsibility for her. Although things have not been easy for the two, Naoto is now content with living at their aunt's place. This newfound peace is suddenly turned on its head when Satsuki Tachibana enrolls at Naoto's school. The two used to be good friends, but after Satsuki completely destroyed his family's garden, she disappeared from Naoto's life. Despite what happened, Satsuki seems to be making advances toward Naoto now that they have reconnected. Coupled with other people around him that harbor secrets, Naoto's desire for an idyllic life may be at jeopardy.

Though he grew up as an orphan, Nio Chirinu finds a place to belong: being a waiter at his adoptive grandmother's restaurant. But this peace does not last long; Nio and his sister Iroha are used as bait to arrest child abductors by Toshizou Hijikata and Souji Okita—two members of an infamous ronin group called Miburo. After the ordeal, Toshizou proposes that Nio join the ranks of Miburo and protect the people of Kyoto. Frustrated by his own weakness, Nio trains to match the swordsmanship of his new comrades. Even so, he struggles to be accepted by Tarou Tanaka and Hajime Saitou, the other Miburo members of his age. Determined to befriend them, Nio must discover his own sense of justice and become strong enough to prevail against all his enemies.

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.
