Iruka’s never known a life outside of the Scarlet Lantern until enemies of Kakashi kidnap him to use as leverage against the powerful jounin. Unfortunately for them, Iruka isn’t as powerless as he thinks he is.
The guard at the front gate was a thick, burly man named Raiden. He was a former special jounin, well past his prime, and he said nothing, only nodded once in silent greeting as he let Kakashi into the compound. The Scarlet Lantern was not officially tied to Konoha but enough of its ninja frequented it to give it a bit of a reputation among the rank and file.
Kakashi had first learned of the Lantern’s existence three months after he’d made jounin rank. He’d been on a mission with an older ninja, a man named Gato, who at the time had held a fancy for one of the ladies at the Lantern. They’d stopped there on their way home and Kakashi remembered sitting awkwardly in one of the private rooms with a buxom young blonde that Gato had insisted on paying for, arguing that if Kakashi was old enough to fight for his village, then he was old enough to enjoy the things he might never live to be of proper age for.
He hadn’t touched the girl and she hadn’t seemed to mind. They’d sat on the edge of the bed, two feet of open air between them, while she prattled on about her home village and he stayed silent. He’d thanked her at the end, when a servant had tapped discreetly at the door to let them know that Gato had finished.
