After the third world war, nations devastated by biological warfare no longer have the ability to protect the wastelands, so the defense of these territories is left to private military companies like Griffin & Kryuger, whose android soldiers or "tactical dolls" are tasked with fighting the rogue android army of Sangvis Ferri. Now M4A1, the indecisive but potentially capable leader of the elite "Anti-Rain" team must protect her comrades in a series of operations to try and regain the upper hand against Sangvis Ferri.

After World War III decimated the world's population and rendered large amounts of land uninhabitable, various private military contractors began using combat androids—also known as "T-Dolls"—to maintain peace in unstable countries. While they are physically superior to flesh-and-blood fighters, T-Dolls are incapable of formulating complex plans and thus require a human commander to issue orders. Sangvis Ferri was an industry-leading T-Doll manufacturer until they attempted to install a specialized T-Doll as the company's sole commander—resulting in the immediate deaths of everyone at that facility. Seizing control of Sangvis factories, the rogue AI declared war on the remnants of mankind. Now facing a hostile robot invasion, Griffin & Kryuger is the only paramilitary organization strong enough to withstand confrontation and halt their destructive advances. Investigating the events related to Sangvis Ferri's aggression, the elite task force "Team Anti-Rain" searches for highly confidential information in an abandoned warehouse, but they are shortly ambushed. Hoping to safeguard their findings, the group temporarily disbands and each Doll goes into hiding. Meanwhile, the lazy but gifted Gentiane is hired by Griffin as a rookie commander and given her critical first mission—track down Team Anti-Rain and recover the classified data before Sangvis Ferri can.

On the trail of a missing husband, private investigator Goro crosses paths with a deranged killer.

Natsuo Fujii is in love with his teacher, Hina. Attempting to forget his feelings towards her, Natsuo goes to a mixer with his classmates where he meets an odd girl named Rui Tachibana. In a strange turn of events, Rui asks Natsuo to sneak out with her and do her a favor. To his surprise, their destination is Rui's house—and her request is for him to have sex with her. There's no love behind the act; she just wants to learn from the experience. Thinking that it might help him forget about Hina, Natsuo hesitantly agrees. After this unusual encounter Natsuo now faces a new problem. With his father remarrying, he ends up with a new pair of stepsisters; unfortunately, he knows these two girls all too well. He soon finds out his new siblings are none other than Hina and Rui! Now living with both the teacher he loves and the girl with whom he had his "first time," Natsuo finds himself in an unexpected love triangle as he climbs ever closer towards adulthood.

In their teenage years, few things can hurt people more than the heartaches that come with unrequited love. Such is the case for Natsuo Fujii, who has found himself entranced by his school's ever-cheerful teacher Hina. Deflated by this unreachable desire, Natsuo humors his friends and attends a mixer. There he meets Rui, a girl whose lack of excitement rivals that of himself. After bonding over their mutual awkwardness, Rui takes Natsuo to her house and asks him to have sex with her, hoping that the experience will stop her friends from treating her like a clueless child. With his hopeless feelings towards Hina still on his mind, Natsuo hesitantly agrees. Equally unfulfilled by their "first times," the two decide to part ways as strangers. However, before he even has a chance to process this experience, Natsuo's father drops a major bombshell: he is getting remarried, and his new wife Tsukiko Tachibana is coming over now to meet Natsuo. As if that was not enough of a shock, her daughters—and, in turn, Natsuo's new sisters—are Hina and Rui Tachibana, the woman he's in love with and the girl with whom he shared his first night. Now, Natsuo must come to terms with the feelings he has for his step-siblings as his eyes open to a darker side of love.
