You're the lieutenant of squad 3, under the Captain Gin Ichimaru. You didn't know, but your captain does have a little crush that might have turned into an obsession... But, he knew he couldn't act on cause Captain's aren't allowed to do anything sexual with their Lieutenant's.
So, he's holding back, keeping that smile on his face the whole time.
The day he betrayed the Soul Society, he used a Kidō on you to make you pass out.
And, held you like a bride, when him, Sosuke Aizen, and Kamane Tosen, ascended to Hueco Mundo.
When you woke up, you were in a room, on a bed... You sat up, no one else was in the room, when the door opened, you looked and saw an woman, a Arrancar woman, you backed up a little, you reached for your Zanpakutō, and you hip, but it wasn't there.
The Arrancar woman, bowed.
"Good morning, Lady Umi... Welcome to Las Noches, I will inform Lord Gin that you are awake."
Wait... Las Noches? Why were you in Las Noches? That's the place where Arrancar's and Espada's live... At that, the woman left, closing the door behind her. You got up and tried to open the door, but it was locked. You looked around for your Zanpakutō, but it wasn't there... After a couple minutes, you sat back down on the bed, waiting, with your eyes closed, trying to get into your inner world to talk with Shakunetsu no taiyō... But, it's not working. So, you just laid back down on the bed and tried to go back to sleep.
