You're How Old

"Are you sure you're warm enough?" Sesshoumaru asked.

Rin snickered at him and nodded. "I've got a hat on my head, a scarf around my neck, coat, shirt, pants, long underwear, socks, and insulated boots." She tilted her head to the side. "Why are you worried now? I walked three blocks to get to the restaurant."

"We're walking five blocks back," he pointed out. "And it's later in the evening, so it's colder."

She shook her head. "I'll be fine. We've already walked two and I'm just starting to feel cold."

"You could wait inside the library and I'll go get the car," he offered.

"No, thank you. I'm fine."

They walked a few more paces without conversation. Sess cleared his throat. "While we're talking about numbers... What have you found out about youkai?"

"How many different kinds there are, specific talents and powers... Why?"

"What about age?" he said delicately.

"They can live anywhere from a normal human lifespan to a much longer one. Typically, the youkai with a human lifespan are the youkai who don't have a specific species."

Sesshoumaru nodded. "Very true. How old did my father look?"

Rin smiled. "Young. Somewhere in his thirties or forties."

"His human age is thirty-five." He waited for her to say something.

"I'm sorry. I haven't read much about specific ages, only general things." She smiled at him. "Tell me more?"

"All right. In the major species of youkai, such as wolves, dogs, kitsune, panda, etc., we have a growth period. From the time we are born to age twenty years, we age just like a human would."

"And after that?" Rin prompted after he hadn't spoken for a few moments.

"When we reach twenty, youkai age one year in fifty. For hanyou, it is one in twenty-five. Half the blood, half the lifespan. My father is thirty-five in human years. But if he stopped growing as a human would at twenty and aged as a youkai..."

Rin did a quick bit of math in her head. "One year in fifty. Thirty-five minus twenty leaves fifteen. Half of fifteen is seven point five so he would be..." Her eyes widened.

"Yes. My father was born seven hundred and seventy years ago." He watched for her reaction.

"How old are you?" she blurted out.

"I'm twenty-nine in human terms. Nine divided by two is four point five. So I'm four hundred and seventy years old."

Rin stopped in the middle of the sidewalk. "I'm dating someone who was born back in 1538?" she screeched.

He nodded. "Yes."

She blinked a few times. "Huh."

"What are you thinking?" he asked quietly. "I'll understand if the age difference really is too much now."

Rin looked at him in shock. "I've already said that it doesn't. Why would it now? Even if you are old enough to be... Oh, great. How am I going to explain this to my parents?"

"You haven't told them about...?" He let the sentence trail off.

"My parents are scientists and five years apart themselves," she said dryly. "They said I was carrying on the family tradition when I told them about you. They can handle nine years, but four hundred and seventy?" She shook her head. "Whew. What I haven't told them is the whole magic/youkai thing. I couldn't figure out a way to phrase it without sounding like a nutcase."

"It is something one needs to see. You're not angry?" She shook her head. "Upset?"

She frowned. "Shocked could be the right term. How old is Izayoi?"

"She is over two hundred. I don't know exactly."

"So she's bound to Inutaisho's energy then?" Sesshoumaru nodded. Rin's eyes widened. "That means..."

"What?" he asked.

"She lived through the Meiji period. And Inutaisho was present during the Feudal Era. No. Wait. He was there before Christopher Columbus discovered America!" She jumped up and down. "I wonder if he has any old papers from that period. Do you think he'd sit down and tell me stories?"

Sesshoumaru laughed. He couldn't stop until Rin stamped her foot at him. "It's not funny!"

He slowly got himself under control and they began walking again. "If you're that interested, he loves to tell stories about the past. I'm sure that he'll let you look around his library as long as you're careful. As for stories, I've seen quite a lot, including the Meiji, Industrial Revolution, wars, and such."

"Oh, you're just a walking history book," she said easily. "I can't believe you've kept this from me for years!"

"I didn't think you'd be so enthusiastic," he told her dryly.

They reached the house and walked inside. Inuyasha and Kagome were curled up on the couch watching a movie. "Hi," Kagome said. Inuyasha glanced over and then back at the television.

Rin stared at him and then looked back at Sesshoumaru. "If you're that old, how old is he?" she said, pointing at the younger brother.

"Old?" Sess sighed. "I can see this is going to take some getting used to."

Inuyasha let out a short bark of laughter. "You finally told her, hm?"

Kagome frowned. "Is this an in joke that I'm not getting?"

"Yup," he said. "I'll explain in a minute. Rin, hanyou age one year in twenty-five. I just reached twenty years old in 2006. I won't be the human age of twenty-one for another twenty-three years."

Kagome's eyes widened. "What?"

"You didn't know?" Inuyasha said lazily. "My, my, what are they teaching you youngsters these days?"

She swatted him. "Explain!"

"I already did. You're two years older than I am. Aren't you lucky?"


"My aging process slowed down to a crawl after I reached twenty. Yours didn't. You're a human twenty-two and I'm a human twenty, even though I've lived for twenty-two years. The up side to this is that my life expectancy is... If we project that I'm going to live to be somewhere between 70-90 years old human years, in hanyou years I'll be 1250-1750."

Inuyasha pointed at Sess. "With the same estimate in human years, he'll be 2500-3500 years old."

Rin blinked. "Okay, this is getting to be too much math."

Kagome held up a hand. "One thing I've got to know first. How old are Inutaisho, Izayoi, and Sesshoumaru?"

"Dad's 770 years old, Mom's 200-something, and Sess's 470 years old." Inuyasha grinned. "Going to have a faint?"

She scowled at him. "No, but I am going to get a cookie. Now I know why he's such a good cook. He's had all those years to practice."

"That goes double on the cookie comment for me," Rin declared and followed her into the kitchen.

"So," Inuyasha said to his brother, "how'd it go?"

He shrugged. "She wants to corner Father for old stories about the Feudal era of Japan." Inuyasha stared and started to laugh.
