Sometime after Ash's adventures with Goh, he gets Abducted by aliens, he gets out and ends up exploring the community, eventually hearing about whispers of a secret organization trying to create a bio-weapon, due to his own interactions with such things in the form of Mewtwo and Genesect, Ash seeks to stop it, little did he know he'd meet a woman he'd come to love(he'd be 21 by this point), Tearju Lunatique. He acts as a double agent and tampers with the programming for a fail safe if Yami, his and Tearju's daughter, were to be taken over by Darkness. However, when the organization collapsed, he lost track of the two, not know he has a second daughter in the form of Mea. He returns to his home planet and defends his place as Alola Champion, while establishing proper relations with other worlds. BUT, he finally makes contact with Tearju again, and she comes to Earth(pokemon). And he ends up with a Harem, consisting of Tearju, Serena, Iris, Lillie, Mallow, and Lana. But when Tearju hears rumors of Golden Darkness being of Earth(to love ru), she leaves to confirm this. Inevitably, she confirms this fact and contacts Ash, who immediately comes to Earth(to love ru) to reunite with his daughter, and lets just say this, Ash is protective of his kids, even if he likes the people they hang around.

-While Ash is her father, Yami does not know this, as Ash was constantly trying to keep Project Eve from being finished, so she rarely saw him. Due to this, she goes through a mild Crisis that Tearju biologically is her mother, rather then the genetic donor to clone her. She also instantly has a fondness towards pokemon upon meeting Pikachu.

-Nana and Momo have only heard about pokemon, and have never seen them in person.

-Yami is a big sister to not just Mea, but Daliah(Serena's daughter named after Ash's mother, 4 years old) and Sun(son of Lillie, Name based around Nebby the Solgaleo, 2 years old)

-Ash is greatly disappointed when he hears about Momo's harem plan, which basically manipulates multiple women into falling in love with Rito, who does not know about said plan, and this included his Wife and Daughter until recently.

-Ash actually brought a group of starter pokemon with him, the children of the starter pokemon he caught at that, Snivy, Squirtle, and Litten, so he could personally give his daughter a Starter pokemon. Imagine how he'll react to his second daughter neither he nor Tearju knew about that was made behind their backs.

-Ash has also become a professor, due to his developed skill when he was in the organization with genetics and programming. He works on helping preserve endangered species that are close to extinction as well as reviving certain species that can safely he revived, as well as making a porygon species that can replace the need to try and capture endangered species, by allowing it to 'tranform' in the species in question.

-Team Rocket was finally disbanded and Giovanni Imprisoned. Ash actually got the help of Jessie, James, and Meowth, so they got a pardon, and now work for Ash as Field researches and protector of his lab, Jessie and James actually have a child named Billy now.(Jessie and James names are based on the outlaw, Jessie James, so I based there child's name on a outlaw as well, Billy The Kid)
