[As Long as There's Love, It Doesn't Matter If He Is My Brother, Right? |Onii-chan dakedo Ai sae Areba Kankei Nai yo ne!|] light novel, manga and anime franchise, with plenty of dialogue and exposition, in which the black-haired, red-eyed protagonist Himenokōji Akito is thinking about his life so far while putting wet clothes on the line. Behind him on the back veranda, 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 Japanese beauty who shares her brother's scarlet eyes, she is also a bro-con with massive feelings for her other brother that she revealed to him during the shared honeymoon Akito had with all the girls in his 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 little sister Arisa Takanomiya, 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 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. Like Akiko and her [Arisa's] older sister Ginbei, Arisa, also known as 'Alice', had incestuous feelings for their [Ginbei's and Arisa's] shared adoptive older brother Akito that she [Arisa], along with the two other sisters [Ginbei and Akiko] acted upon during the honeymoon. Anatasia Nasuhara, a stunning Nordic beauty with short blonde hair and ice-blue eyes, was another member of Akito's harem. The daughter of a Russian oligarch who had fled the country and a Japanese industrial tycoon, Anatasia had trouble understanding social cues due to her upbringing and often preferred to stay by herself. 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 Arashi Nikado, 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 Kaoruka Jinno, the brunette, brown-eyed and busty editor of the company who published Akito's books. Arashi gave birth to twin boys and Kaoruka gave birth to a girl, and both girls [Arashi and Kaoruka] love their [Arashi's and Kaoruka's] children as much as they [Arashi and Kaoruka] love Akito. 
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 Ichika Orimura, 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 before vanishing in a flash of light, heading to an undisclosed location.
