Chapter 4
Before anything else could happen, Tsuna rushed out of the door to greet his new family with a bright smile. "He's joking!" He said with a nervous laugher. "Reborn's always like that." He ignored the glare that Reborn was giving him. Instead, Tsuna noticed that there was a little boy with Natsume. "Who's that?" He asked curiously.
Now normally Natsume would politely reply, but this time he was too shocked at the sight in front of him. Tsuna was covered with cuts and bruises, which instantly put the three guests, including Nyanko-sensei, on guard. Behind Tsuna, the three of them could see a group of teens also covered in cuts, bruises, and strangely enough scorch marks. While they were recovering from the shock, Nana made her way to the door. "Come in, come in. Don't stay out of the house." Seeing their worried looks, Nana quickly stated. "They were just playing a bit. You know how boys are, they usually like to play rough."
That statement got a nervous laugh from most of the teen boys, including Natsume and Tsuna but excluding Hibari. "Oh, thank you." Natsume finally said. "This is Kai." He said, pointing to the young mountain god. "He didn't like for me to leave alone and was worried about me."
Anything that he would have continued saying was interrupted by Tsuna shouting for Chrome. The reason was simple, Reborn decided that Natsume's welcoming should have more of a dose of reality for what he was getting himself into. The banner that had a welcoming sign warmly stated, "Welcome to Hell!" Weapons were littered on the living room, though the living room was out of shape from the small fighting that the guardians had before Natsume arrived. There were also target posters plastered on the walls and what appeared to be an outline of a body on the floor. Chrome quickly did an illusion when she arrived at the scene, which was right before Natsume and the others were led to the living room. The illusion worked semi-well, Nana was oblivious to what really was there in the living room. Natsume and Nyanko sensei could feel that something was wrong, but due to their power levels not being at their peak, they failed to see what was really there. The illusion, however, had no effect on Kai. He saw exactly what was in the living room and gripped onto Natsume tighter. "I am not leaving you here alone." He told Natsume with a firm conviction.
Nana heard this and cooed at the cuteness. "Ara, I remember now." She said, smiling sweetly to the two. "You were the little boy that Takashi was worried about. You're more than welcome to stay here, if you don't mind sharing a room with Takashi."
Kai nodded to her, not really sure if he could succeed in kidnapping Natsume and keeping him placated enough.
When the welcoming feast and party started, Nana was there to supervise things so that it wouldn't get too rowdy and scare of her new family members. Her presence did help to prevent a lot of Reborn's ideas to test out Natsume, which was really lucky for both sides. Natsume was still wary of the other people in the Sawada household. The only ones that seemed normal were the small kids, that was before he saw Lambo taking out a grenade and Ipin effortlessly knocking it out of his hand and into the backyard.
While around the Vongola family, Natsume kept feeling something in the room, but he couldn't see what was the cause, which left him wondering what it could possibly be. Kai and Nyanko-sensei were having a quiet discussion on how they were going to keep Natsume safe from the dangers of both inside the house as well as outside.
Reborn had sneaked out temporarily from the party, the cause was that he needed to do research. He had found out that Natsume kept moving from family to family and the cause of this was that the foster parents could not stand his lying. Reborn decided to keep an eye on him to see what type of lying he would do. When he started to research Kai, he noticed that there were no actual papers proving that Kai even existed. Reborn did not like that at all, with a grimacing expression, he continued to see anything he could come up with. It did not help that he got a weird vibe from both Kai and, in his opinion, the weird cat that came with Natsume. If he didn't find anything, he was afraid that he might have to call the services of some of the other Arcobaleno.
