An hour later.

A group of assassins of ten women had been watching Kai Carter and Shirotsuka Sanae for a while.

One of them was a sniper. Pointing her weapon toward Kai, she sighed. "When will they come back? We won't be able to kill him without leaving any witnesses if this keeps on."

"Idiot, you're always so impatient. You won't be able to go far if you can't be patient," another assassin said.

"I know. This is just my rambling." She pouted. "Still, why would a teacher and a student meet in a family restaurant even though school's off? Don't tell me this is the legendary forbidden relationship?"

"You really are an idiot. That term is no longer known now since it's normal for males to have multiple wives nowadays. Besides, you can watch them studying, right? The teacher must be teaching him because of his grade."

"Can't we just kill both of them?"

"Don't underestimate a teacher from the magical academy. They're veterans in the front lines, and if we're not careful, we might lose our lives in their hands. Especially seeing how young she is, there are two possibilities. She might have been banned from the front lines because of her low-level prowess, or she has her own circumstances despite being powerful since the academy wants her. I assume it's the latter, since there was no way the academy would accept her if she were weak."

"Tch. We can only wait then." The sniper sighed. She was already lucky since she had a friend to talk to for the time being. She tried to observe the other assassins who were close to the restaurant.

Sadly, none of them decided to enter the restaurant to observe him because they knew about his sharp hearing. They were afraid they would be blown out if he heard them.

Of course, they did not know the extent of his hearing, so they just stationed themselves nearby.

…

Meanwhile, in the restaurant.

Kai was leisurely talking with Shirotsuka Sanae after confirming that none of the assassins came into the restaurant. This way, they really looked like they were talking about studies. Little did they know, Kai and Sanae were discussing their plan.

"It seems that they're talking about you. They said you're a veteran with special circumstances who retired from the front lines and became a teacher because of it. Assassins nowadays are extraordinary, aren't they? I mean, they know your circumstances just by observing you for a while. I thought they would have to research your background first before they could know," Kai casually mentioned.

However, Shirotsuka Sanae glared at him. "You better not say anything related to it."

"Sorry, I just wanted to lighten the mood. Maybe I'm a bit too accustomed to Ayaka, since she would most likely panic in this situation and I would need to loosen her up."

"The way you said it is… somehow lewd. What do you mean loosen her up? Do you think this is an R-18 novel?"

"Why are you always talking about things like that? Previously, you talked about p*rn and the like, and now you're talking about R-18 novels. Are you so frustrated to even tease your student?" Kai twitched his eyebrows.

"Heh? Do you think you're a man? I bet you're still a virgin? Do you want your teacher to teach you about this?" Sanae made a smug face.

"So you're not one, Teacher?"

"Of course I'm not."

"So, who is it? You're not going to say it was with a magical beast, are you? Come on, why am I even following this talk of yours." Kai sighed.

"I've done it, and I'm not obligated to tell you," Sanae said with a poker face.

"The way you change your expression from a smug face to a poker face is suspicious. I'll ask Michelle about this, maybe your best friend knows about it." Kai tried to tease her this time.

"Wait! Don't!" Sanae exclaimed in surprise.

With just that expression alone, he already had his answer. "Anyway, enough with this dirty talk. Let's come up with a plan since they don't dare to come inside the restaurant. Well, they might already know about my hearing, so that's good.

"From my observation, there are ten of them. Eight of them are nearby… I'm too tired to even say their position since we're going to lure them out later. The last two are at the top of the tower two hundred meters from us. One of them is a sniper and the other one seems to be protecting her. I'm not sure about it though, since she might come to me the moment I go home.

"Anyway, you're going to kill the sniper first. After that, I'll buy time by saying some random bullsh*t later. As soon as you finish killing the sniper, you'll ambush them first. Remember to take as many as possible in that ambush.

"After that, I'll immediately use my skill, the one you said I need to warn you before using it. We'll then kill one or two more in the chaos. That way, we'll only have less than five to take care of. I'm sure we'll be able to kill them all, but I don't know your ability, so I'm not too sure about this."

"Are you underestimating me?" She narrowed her eyes. "You don't need to worry about my ability. Even in a frontal fight, I still can kill five B-rank elite magicians even though I'm only a C-rank magician. So don't underestimate me, you brat."

"I'm relieved to hear that." Kai nodded.

"Hmm…" Sanae used her left hand to support her head while looking at Kai. She waved her hand up and down. "Come here. I need to say something to you."

"?!" Kai looked at her in confusion. He rose from his seat and came closer to her. He thought she was going to whisper something to him. It was at this moment that she betrayed his trust.

She suddenly hit his head and let his head hit the table. Kai glared at her, "What are you doing?"

"I'm still your teacher, so call me Teacher or something, not 'you'. This is only to warn you," Sanae said.

"You only need to say it to me. There's no need to hit me like that. My instinct almost reacted and I almost attacked you," Kai complained.

"As I said, this is only a warning. But maybe I should teach you who's stronger between us?" Sanae said with a smug face.

"I'm fine with it… is what I want to say, but our situation isn't supportive of that," he said while closing his eyes. "Anyway, that's the plan. Is there anything you want to add, Teacher?"

"Well, if I want to add something, I just want to ask, why don't you call your sister?" Sanae asked nonchalantly.

"I want to, but we're acting separately right now. And since you're here, I can just rely on you while she makes money," Kai told her.

"Hmm… money?" Sanae furrowed her eyebrows.

"Yes. I'm planning to send my parents to the US base and let Michelle take care of them while my sister and I deal with this problem."

"I see. You don't want them to be caught in this mess, huh… Then, why don't you ask for money from that Kudo Ayaka? Although the money required for base transfer is quite a lot, it's just pocket change for her."

"Ayaka, huh… I've thought about it, but Ayaka and I are only friends, so I don't think I'll ask for money from her. I consider it a last resort though. Whether I'll sell myself to Kudo Group or not will depend on your investigation, Teacher."

"You mean 'time'?"

Kai nodded with a serious expression.

"How much time do you think you have to raise money?"

"Hmm… a month." Kai gave his calculation.

"All right. After killing these assassins, I'll try to investigate it. Since it's only about time and not their exact plan, I should be able to get something in 3-5 days," Sanae estimated.

"Yes. I'm counting on you, Teacher." Kai bowed his head to show his thanks.

Sanae nodded. "I think we've already made them wait long enough. Let's go."

"Yeah."

The plan looked perfect, but unbeknownst to him, another danger was coming toward him. There were people coming toward him in another way that he couldn't catch with his ears. After all, two cars were coming their way. Each car had five people in it.

Kai was walking toward his house as though nothing happened. This action lowered the assassins' guard as they thought Kai had yet to realize they were tailing him.

When he was 500 meters from his house, he stopped. He turned back and said, "Who are you people?"

Two women suddenly appeared in front of him. "Under our young lord's order, we're here to kill you."

"Katsuragi Takaki, huh… So nine of you are going to kill me? No, ten…" Kai looked at the assassins.

"As expected of you. We"ve heard about your extraordinary hearing, but to think you could hear that far away," she said with a smile.

"You jest. My limit is only a few hundred meters. I thought you were going for my teacher, as all of you might be her former enemies. But to think I draw such bad luck, sigh…"

"Fufu… you really are capable like our young lord. Interested in losing your virginity before dying? I mean, it will be good if you manage to impregnate one of us, since the child might be born with your extraordinary hearing." She looked at Kai with contempt. She wasn't joking though, since a hearing like Kai's would be regarded highly in the family. And if their children were to have that ability, they might elevate their status together with their mother.
