Behind him on the back veranda of the large, luxurious mansion Akito and the girls of his [Akito's] harem now live in, the girls of his harem cradle their newborn babies while laughing and talking with each other. on the wide wooden porch. The first girl in Akito's harem is his younger twin sister Akiko. A polite and respectful black-haired, short, slender and petite but also somewhat curvy and buxom Yamato Nadeshiko [traditional Nihon-jin |Japanese (Nihon-jin)| beauty |Yamato Nadeshiko|] who shares her [Akiko's] brother's [Akito's] scarlet eyes and [Akito's] black hair, she [Akiko] is also a bro-con with massive feelings for her [Akiko's] other brother that she [Akiko] revealed to him [Akito] during the shared honeymoon Akito had with all the girls in his [Akito's] harem. Next on the list was Ginbei Haruomi, the daughter of Akito's adoptive parents and thus Akito's adoptive little sister. Silver-haired, short with bright green eyes and with a boyish way of talking, Ginbei disguised herself [Ginbei] as a boy and joined Akito's class to get closer to her [Ginbei's] beloved big brother [Akito], while passing off her [Akito] closeness to him as her [Ginbei's] being his [Akito's] childhood friend [Ginbei in the eyes of the world]. Ginbei has since returned to her [Ginbei's] true self as a cute girl ever since she [Ginbei's] and the other girls confessed their [the girls of Akito's harem's] love to Akito, but [Ginbei] worries about being a good mother to her [Ginbei] newborn baby girl. Ginbei's bioloigical little sister Takanomiya Arisa, is [Arisa] also a part of the group of girls that made up Akito's harem. A beautiful russet-haired, red-eyed ball of energy [Arisa] who tries to use her [Arisa's] vast intelligence to make everything interesting, Arisa was a child prodigy who had graduated from MIT at 12 years old, causing a scandal in the United States when it was leaked to the press.

She [Anatasia] fell in love with Akito after he [Akito] unknowingly saved her[Anatasia] from a death squad sent by the CIA. Anatasia is extremely elated to be one of Akito's wives and one of the mothers of his [Akito's] children but is rightly concerned about vengeful government forces finding out their location. The list was finished off by Nikaidō Arashi, the brash and cocky red-headed, amber-eyed and large-chested Student Council President [Arashi] of Akito's school and Akito's older cousin [Arashi] who [who Arashi is] carried around a katana as a symbol of her [Arashi's] noble samurai heritage, and Jinno Kaoruko, the brunette, brown-eyed and busty editor of the company who published Akito's books.

The mood of the story should be one of expectation, fulfillment, and happiness, as the girls and Akito get used to their new lives as parents. The story should end with Orimura Ichika, the black-haired, red-eyed protagonist of Infinite Stratos, watching the whole thing with an amused look on his face from the safety of a nearby tree without being noticed, before [Ichika] vanishing in a flash of light, heading to an undisclosed location. Expectation, fulfillment, and happiness are the main emotions at play as the girls [Akiko, Ginbei, Anatasia, Arisa/'Alice, Kaoruka] and Akito get used to their new lives as parents and grow to love each other [Akito and the girls] more. Although Ginbei is still worried about fulfilling her responsibilities and Anatasia about being chased by vengeful government agents, the girls [Akiko, Ginbei, Anatasia, Arisa/'Alice, Kaoruka] are quite happy with being the mothers of Akito's many children as well as being his [Akito's] loving wives. Eventually, Akiko's friends from her [Akiko's], Anatasia's, Ginbei's, and Arashi's time as students at the prestigious St. Lilianna's Academy eventually come over to the back porch where Akito and his [Akito's] wives are at, [Akiko's friends] heavily pregnant with Akito's unborn children. Akiko's mood is chipper as she greets her friends, and they [Akiko and her friends] discuss the events in their lives while also expressing worry about a series of vigilante incidents popping up across Japan. Meanwhile, Ichika Orimura, the black-haired, red-eyed protagonist of Infinite Stratos, who [Ichika] is [Ichika] heavily implied [Ichika] to be the vigilante [Ichika's alter ego in this story]. after [Ichika] faking his [Ichika's] death after [Ichika] being frustrated with his [Ichika's] life at the IS Academy and the abuse he [Ichika] received from both his [Ichika's] older sister Orimura Chifuyu and his [Ichika's] harem at the IS Academy, [Ichika] watching the whole thing with an amused look on his [Ichika's] face from the safety of a nearby tree before [Ichika] vanishing in a flash of light, [Ichika] heading to an undisclosed location to [Ichika] continue his [Ichika's] fight against crime, his [Ichika's] presence unnoticed by either Akito or his [Akito's] wives [Akiko, Ginbei, Anatasia, Arisa/'Alice, Kaoruka] and [Akito's] consorts [Akiko's friends].
