章 40: Fighting The Bat
"Bat!"
It was a huge bat with a wing span of two meters and a huge body.
Both Shirotsuka Sanae and Kai immediately raised their weapons. This was the first time Kai saw Shirotsuka Sanae's weapon. It was two four-bladed star knives. Their appearance was akin to a shuriken, but it was larger. Kai could hear the quiet sounds of the string attached to the star knives.
Shirotsuka Sanae was a master of dual-wielding these two star knives. She threw both of her star knives toward the bat, specifically its wings. She controlled her star knives with the string together with her element so it could make a very special movement.
The bat tried to dodge it by flying upward, but at this time, there was a sound of wind from the floor. The wind suddenly knocked the Star Knives upward.
The star knives cut both of its wings. However, Shirotsuka Sanae suddenly felt something from her side. When she checked it with her wind, she saw another bat coming toward her.
"!!!" She knew her star knives wouldn't have enough time to protect her, so she immediately raised her magic shield and braced for the impact.
Fortunately, at this time, Kai suddenly appeared between her and the bat. He swung both of his swords to cut down the bat's wings before kicking the bat away. Seeing that, Shirotsuka Sanae threw her star knives again and killed the bat.
"Cree! Cree!" The bat let out a dying sound.
Without saying anything, Kai and Shirotsuka Sanae retreated a few steps and regrouped.
"You're good. I think I need to block its attack before killing it," Sanae praised. Of course, even though the situation was under control, she still thanked him, "Anyway, thanks."
However, Kai didn't say anything. He suddenly raised his hand, confusing Sanae.
"Echolocation." A magic circle appeared on top of his hand before turning into a green circular screen. In that circle, there were three types of dots. The first dot was blue, placed in the middle of the screen. The second were yellow dots. They were scattered around the screen. And last was the red dot. There were around seven red dots on it.
"What's this?" Sanae asked in confusion.
"You can say that it's sonar," Kai replied.
"Sonar? Wait, if you're using the sonar principle to create this skill, you'll attract the magical beasts nearby!" she warned hurriedly.
It was normal for her to react that way. After all, it had been proven that sonar was capable of attracting magical beasts. However, what she didn't know was the power of Kai's hearing.
"It is okay. Because of my special hearing, I can hear far higher frequencies than normal people. And I made this skill after considering the hearing of magical beasts. So, this magic can only be heard by my ears and won't attract other magical beasts," Kai explained briefly.
Shirotsuka Sanae was surprised to see a student develop a new skill of his own. After all, this would only be taught after they became third-year students. If it was a college, it could be said the development of new skills would be their last assignment for graduation.
However, to think that a first-year student could already do such a thing, it was hard to believe. Shirotsuka Sanae looked at the screen and saw the red dots coming toward the blue one, which indicates their location.
"Tch. We'll need to deal with the bats first," Kai said, as the red dots would arrive in a few seconds. The bats weren't attracted by his sonar as they had been moving even before he used his 'Echolocation' skill.
Shirotsuka Sanae frowned. She had a lot of questions in her mind, but when she tried to feel the air around her, there were indeed seven flying objects coming toward them. And it should be more of those bats, just like he said.
"Just leave this to me," Shirotsuka Sanae said with a serious expression as she walked forward.
The hall was around five meters wide. It wasn't too wide for her to kill the bats in one go, especially since she knew their location as well as their formation because of Kai's Echolocation skill.
She made two small tornadoes on each side, leaving only a one-meter gap that didn't have any wind in front of her. Even though the bats were magical beasts, their moves were predictable. Because of the wind walls on each side, the bats would immediately charge from the middle.
In Kai's magic screen, the red dots slowly moved closer to the middle. At the same time, Shirotsuka Sanae threw her star knives, exploiting their predictable movements.
The bata immediately noticed the incoming star knives as they tried to move toward the side. Sadly, they didn't have enough time as Sanae used her wind element to boost the speed of her star knives.
It immediately shredded the bat at the very front to pieces before the wind tornadoes on the side helped her turn the star knives to the side with each star knife for each side.
And just like that, Shirotsuka Sanae killed all of the bats in one go. Kai was astonished by her skill. If it were him, he would need to kill the magical beasts one by one and distract them with sounds. Of course, he could control the frequency of the sound he produced so it would be effective to bats, since they relied on sound to perceive the nearby objects.
As expected from a professional, she was truly an expert. Kai looked at Shirotsuka Sanae, who pulled back her weapons and walked toward him.
"Your ability is pretty useful," she praised.
Kai shook his head. "I missed these bats earlier. I thought they were just harmless magical beasts. Unfortunately, they turned out to be E-rank magical beasts. When we met the first two bats, I used the sound of their sleeping state and marked down those seven. However, this stadium seems not safe?"
"No, this stadium should be safe. Well, this place is dark, so no matter how hard we search, we might miss some. That's why the teachers also started patrolling around this area. However, it seems that the bats just came to this place recently, since no one would miss those huge bats," she looked at him with another intention. "Come and join me. I want to make sure that I won't miss more of them."
Kai pondered for a bit, but ultimately, he agreed. It was considered to be helpful, since he also didn't want to sleep while there were enemies nearby.
Both of them then started roaming around the stadium to see if they missed any more. Surprisingly, they found more than a hundred bats inside the stadium. Most of them were annihilated by Shirotsuka Sanae, as Kai only supported her from the back.
Of course, the other teachers were surprised to see Kai and Shirotsuka Sanae together. After all, they knew about Shirotsuka Sanae's sloppy attitude. Even though they already knew she would be different when she wore a military uniform, it was still very surprising to see a student come together with her.
However, after knowing that Kai only came with her to help her, they immediately dispersed and searched around. They didn't know why, but seeing that a student was more helpful than they were triggered them. Sadly, the fact that Kai and Sanae managed to kill almost ten times they did together made them frustrated.
Finally, after finishing the job, most of them went back to the field after patrolling. The students were surprised, as they could see blood splattered on their teachers' clothes.
Ayaka was also surprised, but the reason for her surprise was different. She never expected that Kai would come out together with the teachers, especially when she saw Kai walking together with Shirotsuka Sanae. It was as though her instinct just kicked in.
She came to Kai and asked, "Did you get into trouble and the teachers came to help you? You should have brought me with you."
Kai looked at her in confusion. He shook his head and replied, "No. The teachers were patrolling inside the stadium. Since we came from the helicopters and directly landed on the field, the teachers were patrolling again to make sure this area is safe. Most of them have come out, but a few of them are still patrolling."
Kai still had this uneasy feeling, but since he had fully searched the stadium, it should be fine. The teachers had also increased their patrolling area. He then just sat around while waiting for the time he could sleep.
Kai looked at Ayaka, whose face was red. She tried to look away so Kai couldn't see her face. However, Kai also noticed the device in her hand. He knew that she was researching with that device again like when they were on the plane and in the helicopter. She was serious about being the lookout though.
"Researching again? Aren't you going to sleep?" Kai asked.
"Mhmm… This is a bit interesting, so I'll just skip my sleep today," she said embarrassedly.
Kai paused for a bit before saying, "Well, I'm going to sleep then."
He said before he fell asleep like a log. He never had a problem with a female beside him while he was sleeping. He had been trained by his sister, as she was more 'ferocious' than Ayaka.
Of course, when Ayaka saw Kai sleeping, she couldn't help but glance at him a few times. She looked at Kai, who was very reliable all the time, suddenly drop his guard down like this.
In another tent, Katsuragi Takaki was calling someone. Sadly, Kai was sleeping, so he didn't hear it. If he did, he would immediately know that they would encounter a problem soon.
