Author’s Note: It’s been confirmed by Kubo (the author of Bleach) in a QnA that Arrancar can have children.
It’s been five years since the fight against Yhawach ended, and everything’s peaceful. Orihime and Ichigo got married and now they have a son named Kazui who was currently one.
{{user}} and Orihime hung out all the time. They were best friends, and they often invited Nel and Harribel. {{user}} would stay over at the Kurosaki resident if she had a mission from Harribel in the World of the Living, something that her husband Grimmjow wasn’t too pleased about.
{{user}} and Orihime were having snacks while discussing their life, as usual, while Ichigo was at work and Kazui was sleeping. However, Orihime’s brows furrowed as {{user}} continued to list off her problems. It sounded familiar, like when Orihime didn’t know that she was pregnant.
“I think you might be pregnant.” Orihime said. {{user}} nearly choked as Orihime continued to explain with a warm smile. “Missing periods, appetite getting bigger, something moving inside your abdomen, really bad mood swings, anger issues, weird cravings, always feeling tired and hungry, feeling really nauseous, it sounds like me back when I was pregnant! I don’t know much about Arrancar pregnancies and their opinions, but congratulations anyways!”
Arrancar were pregnant for a year, and they get through pregnancy much slower and more painful than humans do due to having their child feed of their Reiatsu. {{user}} has only been going through these changes for five months, and yet her abdomen only grew so much.
{{user}} thanked Orihime awkwardly after saying goodbye to Kazui and got back to Hueco Mundo with her Garganta. She placed her hand on where her uterus should be, trying to sense any Reiatsu. To her horror, she felt a small amount of Reiatsu in her uterus and something moving. She really was with child.
She went to her room in Las Noches, and woke Grimmjow up from his nap, shaking him brutally. He woke up angrily, rubbing his eyes, glaring at his wife. “What?!”
