Ichirou Inuyashiki is a 58-year-old family man who is going through a difficult time in his life. Though his frequent back problems are painful, nothing hurts quite as much as the indifference and distaste that his wife and children have for him. Despite this, Ichirou still manages to find solace in Hanako, an abandoned Shiba Inu that he adopts into his home. However, his life takes a turn for the worse when a follow-up physical examination reveals that Ichirou has stomach cancer and only three months to live; though he tries to be strong, his family's disinterest causes an emotional breakdown. Running off into a nearby field, Ichirou embraces his dog and weeps—until he notices a strange figure standing before him. Suddenly, a bright light appears and Ichirou is enveloped by smoke and dust. When he comes to, he discovers something is amiss—he has been reborn as a mechanized weapon wearing the skin of his former self. Though initially shocked, the compassionate Ichirou immediately uses his newfound powers to save a life, an act of kindness that fills him with happiness and newfound hope. However, the origins of these strange powers remain unclear. Who was the mysterious figure at the site of the explosion, and are they as kind as Ichirou when it comes to using this dangerous gift?

Iria is the story of a girl and the Alien being she loves to hate. The series begins with her brother, Gren, taking a job. He is a bounty hunter, and one well known for his incredible skill. Iria, being a skilled apprentice bounty hunter herself, tags along. What is the job, one might ask. It is to find out what has happened to the crew and cargo of a Space Station. Needless to say, nothing is as it seems, and the war between Iria and Zeiram begins in earnest.

While Ichika Orimura departs to visit Kuramochi Engineering's laboratories, an unidentified enemy hacks into IS Academy's core and cripples its systems. To fend off the attack and repair the damage, his older sister Chifuyu enlists Ichika's harem: Houki Shinonono, Cecilia Alcott, Huang Lingyin, Laura Bodewig, and Charlotte Dunois. Together, they utilize virtual reality to confront their opponents in IS Academy's network. Unbeknownst to the girls, a piece of malware named World Purge is activated when they enter the digital realm. The program forces them into fabricated realities, where they each experience an ideal romantic version of their bond with Ichika. Once Ichika returns to IS Academy, it is up to him to rescue the five girls and wake them from this virtual reality.

On a hot day of summer vacation, Charlotte's plan to spend time alone with Ichika at his house is somewhat ruined when Cecilia gets the same idea, later followed by Houki, Lingyin and Laura. The next day, Houki helps out at a summer festival being held at her family's shrine and is surprised when Ichika shows up. (Source: Wikipedia)
