"Get the hell outta here!"
It wasn't something he did every day. But he knew demons had gone into hiding in the modern times, they hadn't just vanished. So sometimes, he did sniff them out. He did go out of his way to stop them before they could possess innocent humans. He may have been half of one himself, but he'd be damned if these peoples' more peaceful lives were going to be ruined.
Then came the near ear shattering explosion to his poor ears.
Creating a barrier with Red Tessaiga wasn't a choice. It was the sword protecting him. He'd been so caught off guard, it had done the work. His ears were screaming at him, eyes burning from the sudden flash. But explosives did exist in the Sengoku Period, he wasn't a total stranger to them. Just... not that bright. The second he could see properly again (he'd landed on his ass), Inuyasha was glancing around, only to see...
"What the hell was that for? Did you make that explosion?" Irritated, but not angry. "I had that handled, y'know. Just a few more swings and that guy woulda been gone. Hell if I'm gonna let some low demon like that possess a poor kid." He shook his head in doglike fashion. "Keh, heard the bastard whispering about it."
