Write an interesting, riveting and groundbreaking fanfiction crossover of Bakemonogatari and Medaka Box, which takes place after the end of both series. Koyumi Araragi also replaces Medaka Box's protagonist Zenkichi Hitoyoshi, as well.

Following the events of both Medaka Box and Bakemonogatari, Koyumi ended up marrying the main girls of Bakemonogatari and also taking Medaka Kurokami, Hansode Shiranui, Harigane Onigase, Mogana Kikaijima, Mukae Emukae, Youka Naze and Myouga Unzen from Medaka Box as his wives too. He ended up impregnating all the girls on their shared honeymoon, causing both him and his wives to move to a mansion he purchased with money he made himself to raise their children in peace.

The story must include these events in chronological order:

Koyumi is thinking about his life while looking out the window of his room through his porch, the events of both Bakemonogatari and Medaka Box going through his mind. As he thinks about his life in the safety of his room, his younger half-sister Sengoku Nadeko runs past his room, rushing quickly to try and sooth her crying baby in its room beside Koyumi's. Behind her, Koyumi's full little sister Karen cradles her twin babies gently while teasing her quiet and reserved twin, Tsukihi, about the fact that Tsukihi got pregnant later than Karen. Tsukhi is rubbing her swollen belly, saying soft things to her unborn child. 

On the porch, Senjouhara and the famous female basketball player Kanbaru, discuss their lives after becoming Koyumi's wives and also put together a plan to deal with Cosa Nostra elements that have started to enter the city. They are joined by Mogana, the brunette money-loving, large-breasted loli high school swim champion, and the three girls start scheming to secure their town and their family, holding their babies in her arms as they put together the scheme. 

In the kitchen sometime after that, the former Student Council President Medaka Kurokami tries her hand at cooking a meal for herself, her baby sitting in a high chair and the other wives and children, while Shinobu Oshino, the busty blonde vampire known as Kiss-Shot Under Blade and before that, the legendary King of Great Britain Arthur Pendragon, watches in amusement in her adult form while using her blood magic to entertain herself. 

Behind Shinobu, the glasses-wearing, busty black-haired loli ex-class President Hanekawa Tsubaka stares in shock and awe, while breastfeeding her baby. Beside Hanekawa, Medaka's older sister Youka shakes her head as she gently cradles her baby.

Myouga Unzen, the stoic and silent busty brunette and ex-Public Morals Committee member, and Asako Kusakabe, the busty black haired ex JSDF member and the woman who was once Mayoi Hachikuji, enter the room with their babies, and are briefly surprised by Medaka trying to cook and Shinobu using her magic to entertain herself. Then Asako remembers that Koyumi accidentally went back in time and saved her from the truck accident that would have made her into a ghost, and decides that being one of his wives isn't the worst that could happen to her. 

Mukae Emukae enters the room as well, and comments on how falling in love with Koyumi has helped rid her of her despair inducing personality. She gently rubs her swollen belly, whispering sweet nothings to her unborn baby.

Ougi Oshino is the last to enter, carrying her triplets in a specially designed basket. The other girls comment on the weirdness of the situation but laugh if off. 

Meanwhile, Kumagawa is trying to live the life of a cartel boss in North America with his powers as a Abnormal, but keeps on being chased by the FBI, CIA and KGB who want the secret of Abnormals for themselves.
