I just thought how hot this pairing would be and went for it.
The story goes Princess Ariel lost her beloved prince to a hollow and the hollow turned on her next. Ariel was about to be killed by the hollow when she saw a Hell Butterfly enter the castle and Renji follows after it. He destroyed the hollow and saved her. She didn't know how to thank him, still scared from seeing the prince dead. Renji appeared to her and tries to calm her down. She became taken by him and felt herself falling for him.
