"We have to defeat Naraku!" Sesshomaru tried to keep his cool as he was trying to explain his thoughts. "The only way is to have as much power as possible. InuYasha, you have to do this."
"This is absurd, Sesshomaru! Me, demon side? Two things that do not mix. How the hell do you plan to make me youki enough for that without killing hundreds of people?"
Sesshomaru put his face in his hands. "There is a 'spell' of sorts that will draw your demon blood into a more prominent place. True it does have some side effects that could happen, it is permanent." His voice leaked impatience.
"So, you're saying that with this 'spell' on me, I'll be more of a demon?" InuYasha was just more confused, but this sounded pretty awesome.
"In a way, yes. The same thing was done to Naraku himself. He channeled his human side into one thing- his heart. Only his took his out to make himself 'immortal' in a way."
"Oh, I think I'm starting to get it now. If I do that spell thing- I will be a full demon, but I'll keep my human heart so that I can tell between friend and foe!" he was now all ears and ready to go.
"Yes. Perfect observation. You do realize that it is dangerous though, correct?"
"Yes."
"Now, when do you want to tell your friends?"
"Afterward." InuYasha crossed his arms in defiance. "They will try to stop me, and then just worry their minds out." He explained.
"Valid point. Now when?"
"As soon as possible."
"Tomorrow it is."

Once again, everyone was out of the loop when it came to what the brothers were doing. This time in the most powerful local Miko demoness' hut. Sango and Kagome had decided to go to the market for a walk that afternoon. Then, all of a sudden, a very bright indigo light came from the hut. Along with pained growls and yells. It seemed that time stopped at the display because the whole market stopped to watch. Even after the light had resided the painful growls and curses continues, to the horror of everyone watching. As soon as it started, though, it ended. That was probably the scariest part. Scratch that, when Sesshomaru and the old lady Miko came out of the hut- without InuYasha was the scariest part, especially for his friends.
Kagome dropped what she was doing and ran. She threw herself on Sesshomaru and pleaded, "Please tell me that wasn't InuYasha." Her eyes were big with fear. The stunned Lord didn't know what to say and just looked at her as she clutched him.
The Miko saved him. "Yes, my dear. It was milord." Kagome nearly screamed his name and tried to push past the two to get inside. Sesshomaru grabbed her. By then Sango had come over.
"Let me GO! What did you do?" the poor girl.
"I don't think you should see him my dear. It may be quite a surprise." The elder lady told Kagome. She pointed at Sango. "Are you his friend as well, young lady?"
Sango nodded. "Why?"
"She needs to calm down. Maybe you should go first."
"Alright. Do you mean that something happened to him?"
"You could say that." The elderly Miko said with a smile.
Kagome paled. "You could say that! What- " Sesshomaru pulled her away- forcefully- as the Miko led Sango inside. By then, the poor girl was in tears.
"Hush. InuYasha is fine. He has just undergone a surprising change and you may be a little frightened at first glance."
"Change?" that's when she saw Sango again. She had paled. 'A demon slayer paling at the sight of someone she sees nearly every day. That can't be good.' Kagome thought. Her voice held venom. "What did you do?" Sesshomaru led her back to the hut. She took one step inside. Two. Three. And fainted. Because sitting in front of her was InuYasha. But, not InuYasha. He had just done the spell he brother and told him about. His fangs and claws were longer, he had two marks on the side of his face, and his pupils had turned to slits. He was a demon- with a human heart.

That day at dinner was fairly awkward. The boys had to not only explain their actions, but had been ridiculed by everyone about the possible bad outcomes to the spell. They were glad when they could all just go to bed. InuYasha was proud that he finally had the power to help more. That evening, he fell asleep with a smile on his face. Which was more than some others could. (Especially after fainting like that earlier.)
