I DO NOT OWN INUYASHA OR BATMAN AND NEVER WILL. THEY BELONG TO THEIR RESPECTIVE OWNERS

Just a warning in advance, but I will be mixing up the universes, hence the word, fanfiction. Edited on 2/18/2019

Needless to say, Damian was not pleased. Not one bit.

This entire time he had believed himself to be the only true son of Batman. It had never occurred to him the possibility of another woman in his father's life before his mother; Catwoman did not count. Standing before him was his half-sister, Kagome Higurashi.

While Damian shared the same dark locks as his father, their eyes had been different. His eyes was an emerald green while his Father's were a sapphire blue. Meanwhile, this Higurashi seemed to be the spitting image of Father, if he had been a woman. Her resemblance to Father was uncanny. If not, frighteningly so. Even the colors of their eyes had been identical to a "tee". The boy grumbled irritably at the notion.

The Robin watched as Grayson coddled her in such a familiar fashion. According to Father, she hadn't visited the manor in over a year. He noticed how both Drake and Todd seemed to be pleased by her return. He felt his irritation grow and a weird feeling in his chest bloom. The duo hadn't exactly been happy when they heard news of his own existence. He couldn't say that the betrayal didn't bother him.

As he kept getting deeper into his thoughts, he realized that she would prove to be a nuisance (to kill). She knew of their secret identities as the vigilantes of Gotham (and how she was just allowed to simply acquire that information was beyond him). It didn't help that her personality seemed to resemble that of Grayson's: Very annoying.

Damian Wayne crossed his arms over his chest, eyes hard, and sneered at her. "How do you expect us to trust you?"

His father called out his name in a disapproving tone. Grayson and Drake frowned. Out of the corner of his eye, he saw Todd hiding his smirk, obviously amused he was not liking the situation one bit. However, the girl just smiled at him, ignoring the others in the room.

"I don't."

He cocked a brow at the statement. Todd's and Drake's expressions turned confused.

"I know I already have everyone's trust here, as for you, I'll have to do it the old fashioned way." Her eyes seemed to twinkle with a mischevious glint. "I'll earn it."

Okay, so I'm just going to say that I'm new to this whole 'post-your-stories-online' thing. I KNOW I'm not the best writer out there, but I'm still learning (and trying for the matter). So, your constructive criticism is very appreciated.
