Write a lengthy, interesting short story in the form of a crossover between the Pokemon: The Series anime [Black and White, XY, XYZ, Sun and Moon] and the obscure light novel, anime and manga series Oniai, in which Ash Ketchum never becomes a Pokemon trainer due to him being adopted by Serena's family as a young boy after a failed assassination attempt on his family by hitmen after his father Giovanni, the leader of Team Rocket. Due to Ash being adopted soon after her birth and her parents never revealing the truth to her, Serena grows up thinking Ash is her biological older brother and has no idea that he is actually adopted. Marnie is Serena's biological older sister by about two years and both girls have a secret incestuous crush on their adoptive older brother Ash, which grows into full-blown love as they grow older. Serena's best friend and future gourmet chef Miette, is actually the daughter of Dellia and Giovanni and thus Ash's biological little sister, which she knows but is unbothered by in her pursuit of Ash. Misty is the Student Council President of Ash, Marine and Miette's high school and is a samurai heiress in addition to being a rather famous Pokemon trainer. Misty is Ash's older cousin and often teases him via sexually provocative poses during Student Council meetings to get his attention, which annoys Miette but has Marnie rather null to the whole affair. Bea is also a student at the school and a member of the Student Council and has feelings for Ash as well. Ash is aware of the feelings the girls in his life have for him but plays dumb, because he doesn't want to be a father just yet and he wants to finish his education. 

Jessie, who works as an editor when she is not working for Team Rocket, becomes rather concerned about Ash as he sends in his novels for publication under an alias, as she notices that his feelings for his sisters and the other girls are seeping into his work. As she helps Ash mature as a writer and deal with his situation, she finds herself falling in love with Ash as well. 

The story ends with Serena's friend Iris coming over to the mansion where Ash and the girls now live for a friendly visit at the same time Jessie decides to investigate Ash's home life, only to be surprised when both females see Serena in an outfit reminiscent of a 50s housewife, cooking lunch for Ash and the rest of the mansion's residents while staring at an oblivious Ash with a love-struck look on her face. Feeling jealous, Iris jumps in and decides that Ash is hers as well, and the other girls jump in to try and keep Ash for themselves. Jessie stares at the whole scene, her face red with lust but her role as a professional stops her from going any further.

Meanwhile Red, the legendary Pokemon trainer from Ash's hometown of Kanto, is walking through the wealthy section of Unova to collect his payment for mercenary work when he hears the girls fighting over Ash. Wrongly assuming that some sort of illegal activity or ghost-type Pokemon is going on, Red ignores it and continues going about his business, oblivious to the truth about what is going on.
