On the top of the building, a hundred meters from Kai's position, Shirotsuka Sanae had been following the sniper this entire time. Luckily, the one who was previously guarding her had gone away to go after Kai, which made her job easier. As long as she could sneakily approach her, then she would be able to kill her swiftly.

She took out her star knives, ready to throw them to the sniper. Sanae chose to wait until the sniper touched the trigger. Because at that time, the sniper would be focused on the trigger instead of her.

One minute…

Two minutes…

She was waiting. She knew they didn't have much time, but if she wanted to take care of the sniper without anyone noticing, this was the only way.

It was at this time that Shirotsuka Sanae found an opening. The sniper turned on her laser and pointed it at Kai's chest.

She threw one of her star knives upward, letting it make a parabolic movement before piercing the sniper's head.

"!!!" The sniper felt the pain on her head, and she died.

Shirotsuka Sanae didn't say anything as she saw a communication device. She didn't want to be found out anyway. She then jumped out of the building before using her wind magic to reduce her falling speed.

After she descended, she immediately snuck around the area to get as close as possible.

...

Meanwhile, Kai's situation.

"Enough with the dirty joke, I'm sick of it." Kai sighed.

"No no. I'm not joking with you. If our children have such a useful ability, then our status will be elevated in the family, even if it means we're going to have to raise the child alone," she said.

Kai looked at her and noticed that she wasn't lying. It made him wonder what kind of life they had gone through in the Katsuragi family. But that was all. He never cared about them anyway, since they were planning to kill him.

"Unfortunately, there's no way I'll be interested," Kai said while closing his eyes. "So, who's going to kill me?"

"I see." She was talking to Kai because she underestimated Kai's power since he was only a student classified as a D-rank magician. Usually, she and her team would swiftly kill their targets, but she became a bit interested in his extraordinary hearing. She decided to talk for a bit since she thought Kai wouldn't be able to escape anyway.

"Well, your life is already gone anyway." She sighed while pointing her finger at the position of her heart. She was telling him to check his heart.

When he looked down, there was a red dot right on his chest. "So, the sniper is the one who'll kill me?"

He looked at the building a hundred meters away from him.

"As expected of you, to think you can even spot her position." She smiled.

"If I had known about this, I would have asked my teacher to protect me." Kai sighed.

"Fufu… Well then, it's regrettable, but I'll have you die here." She raised her hand as the signal to shoot him.

But after a few seconds, Kai was still standing without any magic bullets piercing his heart.

"What?! Mira, hurry up and shoot him," she said to the sniper through the communication device on her ears.

"Well, I've asked her to protect me though. My teacher, that is," Kai revealed with a smile.

"!!!" They suddenly realized what was going on. They took out their weapons, but it was too late. Shirotsuka Sanae appeared behind them and threw her star knives.

"To think you were talking about this. Do you want to lose your virginity that much?" Sanae even had time to tease him. It just showed how easy the situation was for them at the moment.

Because of this ambush, they couldn't react fast enough to dodge the attack. Shirotsuka Sanae chose the place where she could target as many as possible, and she managed to kill three of them. She wanted to kill another one or two, but they were too far apart and would be able to dodge her before the star knives arrived.

"Snake two and snake three will hinder her while the rest will kill-!"

Ding—!

Before the leader could finish relaying her orders, a high-pitched sound reverberated in her ears. The pain it brought to their hearing really wasn't something to be underestimated.

Kai had used small Noise Cancelling magic circles for his ears while Shirotsuka Sanae used the wind to transfer the vibrations upward, so she only heard a little bit of that sound.

Kai took out both of his swords while Shirotsuka Sanae threw both of her star knives. Kai jumped forward and cut through the necks of two assassins without any mercy whatsoever. Shirotsuka Sanae was also the same as her star knives impaled two assassins' heads.

In that instant, there were only two assassins left from the original ten. Both Kai and Sanae didn't say anything. Instead, they immediately went to their respective assassins, who had slightly recovered.

Kai swung his sword toward the leader.

"Don't underestimate me." The leader clenched her sword to block Kai's sword.

They were clashing swords for numerous rounds, but because her movements were a bit dull as a residue effect of Kai's magic, Kai eventually suppressed her by attacking her hand that was holding the sword.

He had no mercy for her even though they were throwing dirty jokes just now. Losing her sword, Kai immediately pierced her heart with his sword. She spat out blood as she walked back and leaned on a wall. She soon fell.

"It seems your ability can really discern the sounds that are a bit more special than the rest." She said as she stretched her hands toward Kai. Her face was full of regret. That hand slowly fell to the ground as she died.

"What do you mean?" Kai murmured as she looked at the assassin leader who had died. He suddenly heard, "Bam!" from two hundred meters away.

He immediately realized what she meant. He could realize he was targeted because they came in a special way through the roof. If they came while camouflaging as normal people and didn't communicate anything special, his brain would automatically regard them as common folks. Unless he specifically scouted with his ears, he wouldn't know.

He immediately jumped toward Shirotsuka Sanae to save her as she couldn't go down just now because he heard that another group was coming and she was the main fighter.

Bang!

Shirotsuka Sanae turned her body the moment she heard that. She was surprised that there was another sniper. But more importantly, she noticed that Kai took a bullet on his stomach area.

"Are you all r-!" Before she could even finish, a woman appeared and swung a giant sword toward them.

Even though he was in pain, Kai immediately swung his sword to block her giant sword.

"!!!" Still, because of the momentum, he couldn't win in strength. Because of this, he and Sanae were blown away to the wall.

There was suddenly another group of assassins. All of them appeared in front of him and made a magic circle. Each of them shot a skill.

"Fire Bolt!"

"Water Vortex!"

"Water Slicer!"

They were raining down their skills toward Kai and Sanae.

Boom!

The dust on the area covered up Kai and Sanae after they were blown up by magic.

"Did we get them?"

"That should be the case."

"But to think they managed to kill the entire Snake group."

"Hmph, the Snake group is just a bunch of lowly slaves. They can't be compared to our Falcon group."

It was at this moment that they suddenly saw two star knives coming toward them from their left and right.

"!!!"

The two star knives managed to kill one assassin respectively, but they were then blocked by the second assassin. All the assassins immediately pointed their weapons toward the smoke and saw a green magic circle. Behind that circle, Kai and Sanae seemed to be fine.

At the last moment, Kai managed to activate his Oscillation Shield and blocked all of their skills. If it weren't because of Kai, they might have died in that barrage of attack. Sanae wanted to say something, but noticing their situation, she didn't say anything and immediately threw her star knives.

There were eight of them left while one of them was a sniper far away from their position.

"Are you all right?"

"Yes, for the time being... I noticed the previous group because they ran through the roof of buildings, so it was easy to pick them out. But to think that these people camouflaged as normal people. I truly missed them until the last moment," Kai said while trying to regain his breathing rhythm. Luckily, it didn't hit any of his vitals, so he only needed to endure it for a while. He just hoped that he wouldn't die because of blood loss.

"Hmph. Don't compare us to that group of slaves. Still, since you've killed two of us, I'll make sure both of you die painfully and brutally," The assassin said.

"I'll take on the five on the right while you take on the two on the left as well as watch out for their sniper," Sanae said. At the very least, she wanted to take the pressure off of Kai. But if she took more than five, the fight might be unbearably long, and it would be bad for Kai.

"Understood." Kai nodded as he looked at the assassins. He took a deep breath as wild instinct slowly took over him. He wanted to finish this battle as soon as possible.

He then jumped forward with both of his swords.
