I don't own Angel Sanctuary or Perfect Blue, this is a fanfic written for the 30kisses community on LJ, where I have claimed Kira/Katou. This was written for theme #3, Jolt.
His door was unlocked when he came home from work at lunch, but the elder Kira didn't think much of it. It was completely possible that Sakuya was skipping class. It wouldn't be the first time Sakuya had cut class, though it was the first time his father would catch him at home.
"Sakuya, why aren't you in class?" Kira's father said, exasperated upon having his suspicions confirmed by finding the jacket of Kira's uniform on the couch.
He received no answer, but heard someone in the kitchen. "Sakuya, answer me, dammit," his father growled, walking into the kitchen to find not Kira, but a blond boy.
The boy looked up from the fridge, grinned, and took off his headphones. "Oh hey. You're Kira's old man, eh?"
"Yes." So, this was one of Sakuya's friends. "Who're you?"
"Katou," The boy, Katou, answered, shifting through the fridge again as if this was the most natural thing in the world.
Kira's father cleared his throat. "Why are you in my house?"
"Got kicked out of my own." Katou frowned thoughtfully, before sighing and sticking a carrot in his mouth. "Figured I'd crash with Kira for a bit. Don't you have any real food?"
Kira's father stood there, dumbfounded. There was no way a boy could be this rude.
"Hey pops, get me a beer," Katou said, kicking his feet onto the kitchen table.
Then again, this was one of Sakuya's friends. Not saying anything, he left the kitchen to go to his room to collect the papers that he had forgotten, and he could vaguely hear Katou complain about how rude he was.

"You've been here all day?" Kira asked as he stood at his stove, making the hungry boy something to eat.
"I was gonna go to class, but I decided not to," Katou shrugged. "Met your old man."
Katou laughed. "Bet he nearly had a heart attack." He grinned deviously. "Hey, I've got an idea."

The elder Kira heard someone whisper a demand when he stuck his key in the door.
When he got inside, he was definitely not prepared for his second jolt of the day.
Sitting on his couch was his son, shirtless. Sitting on his son was the boy from lunch, also shirtless with his pants unbuttoned. Both boys seemed much too engrossed in devouring one another's mouths to notice when he came in until he yelped.
The two of them broke apart, and Katou leaned heavily against Kira, both of them were smiling esuriently.
"Oh, hey pops. You're home already?" he asked with a too-innocent tone in his voice.
