After Gon and Killua ended their battle, they went out together and also added another member that was known as Zushi.
Haru didn't plan to teach Gon and Killua about Nen since he wasn't free enough, but more importantly, their gender was male and he didn't have that much interest in teaching them.
"Haru, what's your plan after this?" Gon asked curiously.
"My plan is to reach 200th floors before tonight," Haru said.
"....."
Gon, Killua, and Zushi were speechless and weren't sure what to say.
However, Shinobu and Charlotte nodded when they reached 100th, they would receive their private room, and the higher the floors they reached, the better their room was.
"If we meet each other, please don't be too hard on me," Haru said.
"....."
Gon and Killua became even more speechless.
Haru, Shinobu, Gon, Killua, and Zushi reached the 50th floor they only needed to wait for their next match.
Then it was at this moment that the announcer from Heavens Arena told Haru and Killua to prepare since both of them would fight each other after this.
"....."
Killua was stunned and his eyes happened to meet Haru's.
"See you at the arena, Killua," Haru said, leaving together with Charlotte and Shinobu since they didn't have an intention to talk to each other with the main characters too long.
"..."
Gon and Zushi didn't go chasing after them and stayed with Killua.
"Killua." Gon looked at Killua with a worried expression.
"Don't worry, I won't lose that easily." Killua clenched his hands and thought to show all of his power in his next match against Haru.
---
Haru then stood in the arena and he could see that he suddenly became one of the most popular fighters on Heavens Arena. It might not be his intention but the people in this world had a very unique appearance and it was very hard to call them good-looking.
Haru's face was very handsome after all and before he entered the arena, there were even a lot of agents from various entertainment industries that came to ask him whether he wanted to develop into an actor, singer, etc.
There was even a rich woman who wanted to keep him which made him even more speechless.
However, Shinobu made all of them pass out easily, using her poison so Haru wouldn't be troubled by all of those troubles.
Haru was grateful for Shinobu's help and it was because of her that he could get into the arena in time. Facing Killua who was standing a few meters away from him, he didn't expect that he would fight one of the main characters right away.
Killua took a deep breath and stared at Haru with a serious expression.
There were no rules that forbid the participants to kill each other during the battle in Heaven's Arena, or rather, death was a common thing in this place.
Killua knew that he needed to fight with an intention to kill or else, he would lose without hesitation. Fortunately, his older brother had planted a needle on his head so he would fight with his 100% whenever he fought against anyone.
"Are both of you ready?" The referee asked both Haru and Killua.
"Yes." 2x
"Then start!!!"
The referee swung down his hand and the match started!
Killua didn't start to attack, but he started to walk around Haru slowly without sound.
Haru didn't move and looked at Killua curiously since it was his first time to see Zoldyk's assassination technique.
The Rhythm Echo was a technique used by Killua. This motion technique made him able to create multiple afterimages of his body through a varying cadence of steps to confuse the opponent.
In simple terms, Killua created a decoy before he sent out a decisive attack on Haru!
Haru knew that the way the assassin would attack was one-hit-kill and he knew that Killua wouldn't attack him unless Killua saw an opening.
'If that's the case...'
Killua who had been trying to search for an opening, without hesitation, dashed into Haru, stabbing his sharp nails into Haru's chest. He had a feeling that he would be successful, however, his wrist was grabbed easily by Haru before his nails reached Haru's chest.
"Come on," Haru said with a smile.
Killua tried to escape, but it felt that his wrist was being held by the hardest steel chain which made him know that his chance to win this battle was...
When Killua was lost in thought for a small millisecond, he suddenly saw the ceiling and he felt time moved very slowly before he could feel that he descended with very fast speed!
Killua knew very well that he was about to be slammed into the arena with tremendous force and knew once he had taken this attack then without doubt that he would receive a lot of injuries from broken bones, internal bleeding, etc... Worst case scenario, his entire body would turn into mincemeat.
Killua felt in that very moment that he was about to be slammed into the arena, he could see the death itself.
Killua was scared and unwilling, but he was hopeless and helpless. He wanted to scream, but then he landed on the ground softly.
"...."
Killua suddenly became confused. In a moment, he knew that he was about to lose his life, but suddenly he landed on the ground softly. He knew that such a technique was quite impossible to perform since he knew very well the speed when he was about to be slammed into the ground was very fast and it was impossible for him to land on the ground softly, even if there was the softest pillow or trampoline under his body.
"Just give up." Haru sighed and said, "I feel bad for bullying you."
"...."
Everyone in the arena was also stuck in place and stunned since the speed of Haru's attack was too fast!
In a moment, they saw Haru caught Killua's wrist, then they saw Killua was in the air, then suddenly they saw Killua landed on the ground with a confused expression.
Some people who watched this fight could tell that Haru was a very strong fighter, but the majority of people thought that Haru was very handsome and dreamy at that moment.
Haru didn't know what those people thought and he didn't care much since he wanted to complete his quest as soon as possible.
"I... I lost..." Killua chattered since he was really scared that he could feel that his pants were wet at this moment. He almost lost his life after all and even though he was from an assassin family, he was only a kid.
"....."
Haru was speechless, but he didn't care too much since this kid planned to kill him before since this kid was too weak to do so.
However, no one liked when their lives were being threatened by someone, but this time, he was merciful since he knew the role of Killua in this world was quite high and once this guy died, then the future of this world would be unpredictable.
Haru walked away after the result of the battle was announced then he noticed the expression of Shinobu and Charlotte who looked at him with a helpless expression. From their expression, he could tell that they were helpless at him who loved to bully the main characters too much.
"....."
Haru sighed and didn't think too much since he had decided before he returned from this world, he needed to settle his relationship with "her".
