This was stupid and pointless and child's play. Why the fuck did he need to practice slaying demons by fighting shit that didn't even move? They were dolls. Life size, impressively sculpted dolls but dolls nonetheless. They didn't fight back. They didn't run away. They just stood there staring blankly ahead while you tried to 'kill' them. On top of everything, it was abundantly clear that half of these children he was training alongside had never held any type of weapon before in their lives. They been picked from universities around Japan for having passed some type of stupid aptitude test. You can be as smart as you want but if you don't know how to wield something as simple as a knife then all the brains in the world ain't gunna save you from getting killed.

"Again," came a harsh voice from the sidelines after Inuyasha cut down three dolls at once with blades of blood, "You were sloppy."

"Not all of us have a fucking whip that adheres to our will, Sesshomaru," Inuyasha clipped back angrily as he set his jaw and gave his brother a side eyed glare, "That attack only hit the dolls. Not the grass or anything else. It's just not as clean as yours."

"Then you need to practice until it is," the daiyoukai responded coolly as he arched a single brow as a challenge, "You never did have any discipline."

"And whose fault is that, huh?" Inuyasha growled out - ignoring the other trainees who were staring wide-eyed at the exchange instead of focusing on the task at hand, "I lived almost all my life alone in the wild learning how to survive while you were sitting pretty. I need something more challenging than this."

"No, you must learn how to hit a non-moving target in a clean, precise manner," Sesshomaru countered before narrowing his eyes and ordering, "Again."

"Bastard," Inuyasha muttered under his breath despite knowing his brother could most likely hear him as he once again rushed forward to attack the dolls once more.

It'd been a strange few weeks. Not only had he had to defeat two adversaries that should've been long dead but now he was being trained to be an assassin by the demon who'd wanted to kill him from birth. Apparently five hundred years had given the daiyoukai time to reassess his priorities and by the time he'd been dropped in the modern era to be with Kagome, Sesshomaru wanted to make amends. More than just make amends, he wanted a second in command. Eventually anyway. The new InuNoTaisho required that his future beta have all the formal training required for such a position. That also included lessons in manners and proper etiquette which was absolutely freaking ridiculous and endlessly infuriating. Why he decided to do this instead of something else was beyond him - all reasons for his decisions seemingly idiotic now that he was in the thick of it. But...but he'd always been someone who'd valued his word. He was a man of honor and he'd never broken a promise before now. Still, fighting dolls was beneath him and he had a sinking suspicion that Sesshomaru was just toying with him. Quickly dispatching the newly placed dolls, Inuyasha walked up to one of them and bashed the inanimate thing's head in with his foot before groaning inwardly when he heard the one word he now hated above all others.

"Again."
