"Do you wait for me, young yokai?" A coy, melodic voice asked, lightly dancing on the sound of the waves.
The yokai turned to her and, recognizing instantly who she was, bowed. The goddess joined his side and stared out across her youngest brother's realm.
"You will not have to wait long," she continued. "I promise I will raise my light. Perhaps I will raise it early, if you ask me to."
"Amaterasu-omikami," the daiyokai said slowly and emotionlessly, but respectfully. "Why do you grace a yokai with your company?"
She smiled slightly as she stared at the horizon. She would not do the action for a long time after this event.
The sun goddess did not answer him. Her white kimono began to glow, subtly at first as dawn shyly spread its light.
"Isn't it odd, young yokai?" He was not used to not being treated without utmost respect – or utter terror – and she knew it. However, he could not find himself to be annoyed with her. "It can be said that my light is most beautiful when I rise over the ocean. However, the ocean belongs to a brother I am estranged with." The sun goddess put a clawed finger to her chin, in a thinking pose.
"At other times, his storms hide my light. I can outshine his clouds and am more revered by the humans. It is only in the quiet times, I think, when no one looks, when we can be in peace."
The daiyokai stayed silent for a moment, thinking over what she meant. Perhaps she was giving him hints, carefully placed and to be discovered at a later date. Perhaps she was simply saying what was on her mind.
The goddess slowly shone over the Earth, urging the humans to wake and the nocturnal yokai to rest. Warmth dripped off of her, and the daiyokai almost reveled in it, regardless how her sheer presence made the air thick with a holy quality that stung at his instincts and senses. Her kimono and hair – much longer than the daiyokai's, who already had a considerable length – blazed with white. Her red markings were the colour of the red, waking sky.
The odd duo watched silently.
Finally, after what felt like hours to the daiyokai and seconds to the goddess, the sun hung in a blue sky instead of a red, multicolored one.
The goddess turned to the daiyokai, who still did not want to leave. "Young yokai, I think you have done enough waiting. Perhaps someone is waiting for you. It's your turn to rise."
Amaterasu watched as the daiyokai inhaled deeply, and turned to her. Sesshomaru bowed deeply for the last time in his long life, and strode soundlessly into the forest.
AN: Why is it that this cross over seems only logical to me? Ah, well. I'll usually prefer to use Japanese words if English has no perfect equivalent, like yokai =/= demons. Because Amaterasu is technically also a yokai and very much not a demon, though I will use the term goddess. Oh, if I get anything wrong, be it historical details or things about Okami and/or Inuyasha, please tell me! I'll look like an idiot otherwise. XD
Also, I'm mixing Okami and actual Japanese mythology here, hence Amaterasu's younger brother. Also note that Amaterasu (and Chibiterasu) won't always be in human form. They can switch.
In any case, please be patient with me if it takes a long time inbetween updates. Don't be afraid to yell at me for it! I write more when I think that people actually read my stuff. XD
