What happens when Inuyasha & Sesshomaru have to coexist?
Inuyasha has a younger sister, named Momoneko (or Momo for short). Shortly after retrieving her from wherever, Sesshomaru comes to fight Inuyasha to see how strong he has become. He however, becomes very distracted by Momoneko. Why is he so infatuated with a half demon? Why does he love her so?
Sesshomaru loves Momoneko so much so that he's "willing" to travel with Inuyasha & group (Momoneko won't just up & leave her brother).
Also, Naraku has been defeated, but Miroku & Sango do not have their family.
Now edited with Grammarly-I have added more details & such to some of the current chapters as well
Yes, Sesshomaru is slightly OOC. But that's what love can do to a person...
Inuyasha and gang were sitting in a field, having a picnic when Myoga showed up.
"Hey!" Myoga exclaimed out of nowhere.
"Oh, boy, this can't be any good." Kagome mumbled.
"I heard that. But this is very important. Inuyasha, this concerns you more than anyone here." Myoga exclaimed, very seriously.
"And why is that?" Inuyasha asked, confused, and annoyed.
"You have to save your sister." Myoga said, shocking everyone there.
"What are you talking about? I don't have a sister." Inuyasha said, looking at Myoga.
"But you do. Let me explain. When you were about six or seven years old your mother met and was tricked into having sex with a powerful cat demon. I think he put her under a spell or something. Anyway, he died shortly after he and your mother had sex. Of course, even after the spell broke, your mother knew what she had done and knew it wasn't rape—to an extent. It wasn't until your mother was about five or six months pregnant, that someone came by, and explained what type of child she was carrying; she would have a half-cat demon. Of course, your mother didn't care; she had you as proof. But the child she was carrying, would have extraordinary powers that others would want to use—just like her father, apparently. Your mother didn't care what these people had to say; she was going to have this baby and take care of it—sorry, her." Myoga explained.
"Where is she now?" Inuyasha asked, interrupting Myoga.
"Don't interrupt me. Your mother gave birth to a healthy baby girl; she named her Momoneko. You helped your mother take care of your sister often; you loved being a big brother. However, when she was about a month old, she was kidnapped by the clan her father came from. She grew up to be about a hundred before they sealed her away until the time was right. Well, I guess the time is right because they unsealed her. They're going to sacrifice her like they tried to sacrifice her father. The big difference is, she's not as strong as her father was; they kept her weak so she couldn't run away. Inuyasha, she's going to be sacrificed to bring back Naraku." Myoga explained, getting everyone's attention.
"Where is she now?" Inuyasha demanded, standing up, determined.
"In the Forest of the Cats. If you leave now, you'll be able to get there before midnight. The sacrifice takes place with the blood moon at precisely midnight." Myoga explained.
"Let's go!" Inuyasha said, determined.
"Hopefully, this sister will like you." Kagome said with hopefulness.
"Let's just save her first." Inuyasha said as they made their way to the forest of the cats.
Several Hours Later:
When they got to the Forest of the Cats, Inuyasha and gang found the spot with ease.
There was a girl who looked almost exactly like Izayoi—except her hair was dark orange, almost brown. They couldn't see her eyes from that far away, but she had brown cat ears on top of her head—and she was crying.
They figured it must be a little before midnight because her crying got worse, and the demons performing the sacrifice were getting everything set up.
"Inuyasha—why are you in the Forest of the Cats?" Sesshomaru asked, appearing out of nowhere.
"What are you doing here?" Inuyasha asked, annoyed.
"I came here to see how strong you've gotten." Sesshomaru simply stated.
"I don't have the time right now; I have to save my sister from being sacrificed to bring back Naraku." Inuyasha stated before taking off.
"Hey! Let her go!" Inuyasha yelled, interrupting the ceremony.
"Who are you?" Everyone asked, looking at Inuyasha.
"It's the brother…" An elder said, relieved; he didn't want Naraku to be revived.
"She has a brother—who is a dog?" Murmurs were heard.
"He's just a half-demon, we can take him!" Several of the cat demons yelled.
"Yeah? That's what Naraku thought before I killed him." Inuyasha retorted, sending the cats into a rage.
Using his Tessaiga, Inuyasha was able to kill half of the cat demons who attacked him. However, he was too distracted to see that the cat demons' leader cut the ropes holding his sister up until it was too late.
'With all these damn cat demons, I'll never get to her in time.' Inuyasha thought to himself.
"Ahhh!" Momoneko screamed as she fell.
Suddenly, a flash of silver swooped over and saved her before she fell into a glowing pit.
"Sesshomaru?" Inuyasha asked, shocked before having to get back to fighting off these damn cat demons.
"Need some help?" Miroku, Sango, and Kagome asked as they joined the fight.
"Thanks." Inuyasha said as they continued to fight; his mind, however, was elsewhere.
"So—you're Inuyasha's sister? It makes sense; you like that Izayoi woman." Sesshomaru said, untying the girl; he then looked into her eyes, and something happened.
"Hey, wait! I never got to thank you—" Momoneko called and then softly said as she made her way down to wherever everyone else was; she had to meet this brother of hers.
Sesshomaru had left to join the fight against the cat demons—mainly because he hated cat demons—or so he thought.
"I think that's all of them." Inuyasha said, looking around.
"Good; we can see just how strong you really are." Sesshomaru challenged, looking at Inuyasha, pulling his sword out.
"Really?" Inuyasha asked, annoyed.
"I'm not holding back this time." Sesshomaru said as he went to attack Inuyasha.
"You, hold back? Never!" Inuyasha exclaimed, blocking his brother's attack.
"Go, Lord Sesshomaru!" Jaken yelled as he and Rin showed up.
"We best stand back." Miroku said, pulling Kagome back while Sango got Rin.
"They seem to at least not hate each other anymore." Kagome said as they watched the two brothers fight.
"Watch your tongue! Sesshomaru hates his younger half-brother with a passion!" Jaken yelled, interrupting the fight.
"Jaken, shut up." Sesshomaru growled.
"Is it this way?" The group heard a young girl ask, sounding lost.
"Hey, it's Momoneko." Kagome said, getting Inuyasha and Sesshomaru's attention.
When Sesshomaru saw Momoneko, he immediately stopped in his tracks and stared at her; she stared back at him.
"Hi. I don't mean to interrupt. But uh… Thank you for saving me up there." Momoneko shyly said.
"Whatever. Jaken, Rin, come on." Sesshomaru said, taking off.
"What the hell was that?" Inuyasha asked, annoyed.
'I'm not sure—but I think Sesshomaru likes Momoneko.' Kagome thought to herself—and she would keep that thought to herself forever.
"Umm… Your name is Inuyasha?" Momoneko softly asked, looking at Inuyasha; her eyes were reddish-brown like Izayoi's.
"You look just like her." Inuyasha said in shock.
"Excuse me?" Momoneko asked, confused.
"Sorry. Like our mother; you look like our mother." Inuyasha said, looking at Momoneko and then past her.
"Watch out!" Inuyasha yelled, waving his sword; two cat demons were coming from behind Momoneko.
"It's true—you're my older brother?" Momoneko asked, shock after he killed the cat demons.
"I guess so." Inuyasha said, still in shock.
"Are you ok?" Momoneko asked, worried.
"Yeah. You just look a lot like mother." Inuyasha answered again.
"I see. I'm sorry. I change on the new moon." Momoneko replied.
"Yes, I know; so do I." Inuyasha gruffly said.
"Right. You're a half-demon as well." Momoneko said, looking Inuyasha up and down.
"Who was the other guy? The one who just suddenly left? Did I do something to upset him?" Momoneko asked, confused.
"That was Sesshomaru; don't worry about him. He's just my older half-brother; he hates almost everybody." Inuyasha calmly said; he could tell this girl was easily spooked.
"Oh— Ok—" Momoneko distantly said.
"Anyway, the people you do want to get to know are over here. This is my girlfriend Kagome and our other friends, Shippo, Miroku, Sango, and Kilala. Everyone, this is my sister Momoneko." Inuyasha said, still in shock, introducing everybody.
"It's nice to meet you all—but how do you know my name?" Momoneko asked, confused.
"I told them." Myoga said, appearing out of nowhere.
"Myoga, it's good to see you again. But where were you when the fight was happening? Did you cower your way out again?" Momoneko asked, looking at Myoga.
"Even she knows you're a coward." Inuyasha said, looking at Myoga.
"You are so adorable!" Kagome exclaimed, hugging Momoneko.
"Thank you. You can just call me Momo if you'd like." Momoneko said, looking at everyone.
"Absolutely adorable!" Kagome exclaimed, once again hugging Momoneko.
With Sesshomaru :
"Lord Sesshomaru, are you ok?" Jaken asked as Sesshomaru when from standing on a cliff, watching the sea, to destroying the cliff.
"That girl… What is it about that damn girl?" Sesshomaru asked, frustrated, sitting at the bottom of the cliff.
"What girl?" Jaken questioned, bewildered.
"Inuyasha's little sister." Sesshomaru growled like Jaken was supposed to know that.
"The really pretty cat-girl? I heard her name was Momoneko." Rin happily said.
"Rin, hush." Jaken hushed Rin.
"No—Jaken, you shut it. Tell me Rin, what else did you hear about this Momoneko?" Sesshomaru asked with great interest…
