Krixae was always used to being the youngest. She'd been the youngest of four when she was a Somebody. And with her sickliness she'd have to rely on her older siblings to take care of her. After the fire that claimed her life, there had been at least a few mercies. The cancer was gone and she'd unlocked new potential, magic and strength from within. But not everything was fixed. Her appearance was frozen into that of the sick girl she'd been, still pale, still weak. Her physical strength would never be what it once was before sickness decided to make her its plaything. And her sickliness remained. So it wasn't much of a surprise that she quickly grew attached to a few members of the Organization. Xasech was a close acquaintance, and a peculiar person at that. Not very many people tried to make friends with him. Xirama was an obvious choice. She was so bright and full of energy; she always brought a smile to Krixae's face. Krixae also quickly bonded with Roxas and started to fall for him. But it was undeniable that there was one person she trusted and cared for more than anything. Caixsa.
She wasn't quite sure what had first drawn her to him. Maybe it was when she found out he'd been from Twilight Town too. Or when she realized their deaths had been almost simultaneous. Either way, Krixae began trusting him more than anyone. As time went on, Roxas grew to the same level of trust and love, but Caixsa had taken his place as Krixae's brother first.
It was a solo mission to Agrabah. Check on the Heartless population, do a bit of recon, it should've been easy. But while exploring the desert, illness decided to step in. She grew overwhelmingly nauseous and vomited over the sand. As wave upon wave of Heartless attacked, Krixae could only fight to stay alive. But when they dispersed, dehydration and weakness set upon her and she fell unconscious. When she awoke, she was in her room, Caixsa asleep in a nearby chair. She later heard she'd been out for three days and he hadn't left her for a single moment.
It was a post-mission trip to Twilight Town. Krixae and Caixsa wandered around, looking at the sights and memories from their pasts as Somebodies. Then she saw them. Her older siblings, walking around, chatting like nothing bad had ever happened to them. As soon as Caixsa realized who they were, he took her home to the Castle; to his room.
"It's not fair." She'd cried into his shoulder. "I see them but I can't speak to them. And did you see how happy they were? They've forgotten me."
"No, they haven't. Trust me. No one could forget you." He hugged her tight and rubbed her back. "I bet they're happy for you. They know you want them to be happy. They're honoring you." Somehow, no matter what, he always knew what to say to comfort her.
Some considered becoming a Nobody a blessing. Others, a curse. Krixae could see both the good and bad from her transformation, but she knew one thing for sure: if she hadn't become a Nobody, she wouldn't have met her big brother Caixsa.
