Empress as sister
The Pirate Empress, Boa Hancock, dubbed the Most Beautiful woman and Tira can't disagree. Beauty exisits but Hancock's beauty comes from somewhere else that many other people don't get a glimpse.
Hancock and her sisters went trough literal Hell and still they stayed strong together. For girls to be enslaved then tortured in every way possible for years Tira can't imagine that. At least Big Mom had some moment when she rewarded them and she had freedom to move around the island.
How did Tiramisu meet with Hancock? It was an interesting story, when she was barely seven Mama already wanted to set up an arranged marriage for her, it was after that trip that Tira trained hard to avoid marriages like Smoothie did.
Katakuri and Raisin were with them they went trough Fishman island because they had some pirate buisness in Paradise beside the marriage.
It later turned out as a fluke, Big Mom had a feast that day both her fiancé and his sister were eaten and they looked so kind when they turned Mama down.
Tira didn't mind at all at least she has time to save herself from a marriage. She wanted to be like Katakuri a Minister.
Tiramisu wandered off Sabaody looked soo cool and it had a ferris-wheel too! She wanted to try it out and have some fun. Of course her being a Yonko's kid she laid low and Mama was angry anyway.
This didn't stop her to not wander around of course even seeing a teenager girl. She walked up to her.
"Hey! Sorry to bother you but I got lost." The girl had dark brown hair and sea blue eyes. Tiramisu actually loved them. Tira found herself later in her life dreaming about those eyes.
"Get lost brat!" She said and ran away quickly clearly she was hiding from someone.
"Wait I can help you hide!" Tiramisu tried to be helpful but she was ignored. "Would anyone look for you in the ferris-wheel?" The teenager stopped to think.
"I don't think so." She walked back to her. "Why would you want to help me."
"Because Mama is angry and I need a hiding place too.
"Okay but after that I need to look after my sisters." She looked uncomfortable.
"I will help." She promised.
"Boa Hancock." She said proudly but her pain was clear on her face.
"Charlotte Tiramisu, you can call me Tira it can be a moutful."
The girls spent a wonderful ride on the ferris-wheel then Hancock and Tira looked after Sandersonia and Marigold.
Hancock out of gratirude hugged the little girl then they parted way. Tira was left with this memory for decades feeling that Boa Hancock was more of her sister than her blood relatives.
Hancock still tried to think back to her life she hated a lot of people, tolerated a few and only loved her sisters and Luffy. But there was someone she liked, not as a crush, not as a friend maybe as her third sister. A seven years old brat who admitted how controlling is her mother, how she hates arranged marriages and that maybe she loves girls. A girl who sailed away after helping hiding her in the ferris-wheel, found her sisters then kissed her cheek.
It is a small miracle that Tiramisu now Tira sails under Luffy-kun's flag. They will meet one day again and that will be the reunion.
Tiramisu won't admit it but when she saw the the Pirate Empress's wanted poster something came back.
She was beautiful, more than any female she has ever seen.
Something came back that her eight years old self felt. A budding crush, a flame that died out. Hancock was her sister not her love. This was before Vivi, before Robin, a long time ago...
"Mommy I don't want to marry to a male." Young Tiramisu said naively after her tiresome training.
"What are you talking about?" Big Mom was ready to lose her mind when her youngest protege cofessed about her feelings to a girl from Sabaody.
"I like Hancock. Can I marry her?" She asked instead.
"Who is that girl who bewitched you?" Mommy looked furious. Young Tiramisu felt sad that she made her mom angry.
"A slave." She admitted. Katakuri explaied her that Hancock was a slave and she will go to Mary Geoise to serve Celestial Dragons. A cruel fate he muttered, but back then she didn't understand.
"You will marry a man, who has infulence or you can be one of my Ministers. But forget your dumb crush on a girl!" She ordered then she was punished by training with Brulee and Smoothie. They left a lot of scars on her.
Of course she never forget her crush but she buried deep inside for years.
She heard about Hancock helping out Luffy in Marineford. Tiramisu hoped to meet with her one day and hug her as her sister and actually get to know Sandersonia and Marigold.
