Tenth Company Captain and child prodigy Toshiro Hitsugaya was pissed off. First, he was sent on this ridiculous mission to America, of all places. Then his gikongan ran off with his gigai and hid in a dumpster, so he would stink when he had to get back into it. And now, the soul he was supposed to konso refused to go.
Admittedly, he admired her a bit. She was only a little taller than him, with grey-blue eyes. Her blonde hair and white dress hung limply around her, dripping wet - she'd drowned. Her severed chain of fate dangled from her chest. And she was glaring at him wholeheartedly.
"I told you already, I'm not going! I can't die here - I've got a world to save!" Hitsugaya growled.
"I know Summers-san, but the fact of the matter is, you're dead. You can't save anyone like that." Not technically true - plenty of shinigami had saved the lives of countless humans - but she didn't need to know that.
"Well, then I'll just - I'll just - I'll un-dead!" she exclaimed. Hitsugaya's eyebrow twitched.
"I'm afraid, Summers-san, that that would be impossible." Summers-san scowled.
"But my body's right there. I bet I can get back into it..." She knelt down and placed a thin hand over her body's right shoulder blade, hovering an inch or two above the soaked fabric and damp skin. Taking a deep, steadying breath, she plunged her hand forward.
It went right through her body, and as she threw herself into it with a little too much vigor, she toppled over into the pool. She wasn't in a corporeal body, so she couldn't get any more wet than she was at her death, but she still emerged spluttering.
"Why didn't it work?" she asked as she hauled herself out of the pool. Hitsugaya sighed and allowed his hand to fall Hyorinmaru's guard. He wondered idly what would happen if he tried to konso an unwilling soul. He decided against it for now, but the idea was quite appealing as a last resort. Instead, he explained.
"Your chain of fate is severed. Now that it's broken, you can't go back into your body. You're dead. For good." He stressed the last two words, hoping she'd get the idea.
Summers-san scowled and sat down on a ledge. "So... what now?" Hitsugaya mentally cheered. Now they were getting somewhere.
"Now you go to the Soul Society, and I go home and hope that it hasn't been burned down by now." he griped. Summers-san's head shot up.
"Home?" Hitsugaya winced. Hadn't meant to mention that. He was saved an awkward answer by a loud crash as two mortal men burst into the room. Summers-san leapt up and ran to them, but they past right through her and rushed to the pool in which her body lay.
"Angel?" she asked weakly. "Xander?" The men pulled Summers-san's corpse out of the pool and argued briefly, before the shorter of the two ducked down and pressed his mouth to that of the body.
Summers-san made a face. "Oh, ew, Xander, that's just aaaaah!" She was cut off as her chain of fate lengthened and snaked out to twist into the one still attached to her body. As Xander-san's breath invaded her corpse and Summers-san's soul was pulled back, she grinned at Hitsugaya.
"Guess I'm goin' back after all." And with that, the freshly revived Summers-san coughed weakly in her own body, and sat up to the joyous greetings of her friends. As Xander-san wrapped her in a fierce hug, Summers-san looked over his shoulder and thought she saw a fading, white and black shape. But surely it was just a trick of the light.
