I have three books I'd like to start making but the question is, which one to start with? I'd like to know everyone's opinions please:

Hypno's Child — The Truth behind a Pokédex Entry
"It carries a pendulum-like device. There once was an incident in which it took away a child it hypnotized." Kanto Region Pokédex Entry.

What is the reality behind the creepy entry that states a kidnapping that once occurred to a child by the infamous Hypno? When did it happen? 1 year ago? 2 years ago? In fact, the entry talks about an event that happened 5 years ago. To a girl. Lost and afraid. Deep in a forest close to her home but far away from reality. Hypno's domain of dreams.

During Ash Ketchum's travels, its easy to say that the young trainer crosses paths with the forest that said Hypno lives in. As it is the girls domain as well. Will they understand the truth of the past? Or be blinded by the lack of detail from a professors recording system.

The Assassin and Her Persona
The daughter of a broken and criminal family, saved by the people of the government...only to be turned into their weapon by the advantages of her lack of emotion and pain.

She kills for them, obeys everything from them, she lives for them. How will it affect her when the government start to become corrupted and use the advantage of her weapon-designed mind to kill off people who would ultimately overpower the current head of the governing system? Nothing, shes been trained to understand only that a target is a target and nothing more.

That is, of course, until she meets the next line of targets before they become her targets. When they invite her into their group happily despite her blunt responses and blank expressions to their joy and despair. When she starts to understand human emotions. Only to have to take it away from herself with her own hands.

A One-Voiced Love (Kiawe x OC)
"she's a Pokémon?!"

"Technically yes, but actually no. Rotom will explain I'm sure."

"Serah, the Kaikamahine Pokémon. Whilst she has the genetic structure of a human, Serah has a strange and unique ability to possess and use Psychic- and Fairy-type moves which has led researchers to believe that she was raised by the Guardian Pokémon Deity, Tapu Lele of Akala Island since a very young age. Those who have managed to gain verbal communication with her have noted that she repeats her name as a Pokémon does."

What is the reality behind the human child that speaks and acts like a Pokémon? Is she really human? Or another Ultra-Beast to capture? Technically...she's both. The gang follow her movements and eventually start to teach her how to be more human than Pokémon. Though its hard to make strong relationships with a girl that only Pokémon understand. Leaving it up to the Pokémon to convince Kiawe that the Psychic and Fairy empowered girl has romantic feelings for him.
