The skilled craftsman Kuroda created artificial humans called Hybrid Child—creatures who are neither machines nor dolls, but rather a reflection of the love shown to them. While they can feel human emotions and have their own consciousness, they are not real humans and require love to grow. Kotarou Izumi is the young heir to the noble Izumi family, so it is frowned upon when he brings an abandoned Hybrid Child he found in the garbage into their household. His family even attempts to throw away Hazuki—Kotarou's name for the Hybrid Child—multiple times when he is not paying attention. But through overcoming these obstacles, their love and the bond connecting them grow stronger. However, ten years pass before a horrifying realization dawns on them: a Hybrid Child might not have an endless life span. Hybrid Child is a collection of three short love stories, depicting the relationship between the artificial humans and their owners.

Private Tenshou Gakuen is the seventh of ten school districts circled within a 130-meter tall wall with restricted entry and egress aside from officials. The academy is fully autonomous by the government but to strive for independence, the school allows students to engage in club activities after school, which comes with a strangely unique system. Each club is ranked according to its overall accumulated points gathered from various club activities and school events. Points can also be received by winning at the school's periodic Tenshou Gakuen Singing Contest, where many students compete. The members in the clubs work hard to win the contest for their goal.

—Do you know the Nejen? If you know it, then I'll take you there— The year is U.C. 0105. Twelve years have passed since the end of the second Neo Zeon War (Char's Rebellion). Even after "the Axis Shock," which seemed to indicate the future of humanity and the Universal Century, the world is still in a chaotic situation where intermittent military conflicts continue to break out. The Earth Federation government is more corrupt than ever, and its leadership has not only accelerated Earth's pollution, but also implemented an inhuman "Man Hunting" policy in which civilians are forcibly exiled to outer space. The anti-Federation government organization "Mafty," led by someone called "Mafty Navue Erin," has taken a stand against the corruption of the Earth Sphere. Mafty carries out fierce acts of terrorism, assassinating high officials of the Federation government one after another, but it gains a certain level of support from the populace who are growing more opposed to the Federation government. The person who calls himself "Mafty" and leads this organization is Hathaway Noa, the son of Bright Noa, an officer of the Earth Federation Forces who once participated in the One Year War. Hathaway himself joined the forces trying to stop Char’s Rebellion. With firsthand knowledge of the ideals and ideologies of Amuro Ray and Char Aznable, he has become a warrior following in their footsteps, and plans to clear a path forward through armed resistance. His destiny, however, is drastically altered as he encounters the Federation Forces officer Kenneth Sleg and a mysterious young beauty named Gigi Andalucia. (Source: Gundam.info)
