"It seems today's lesson is supposed to be no sex. So boring." Cirno lay on the desk, looking miserable. For them, who were used to having sex with Kars during class, this was quite a difficult thing to endure.
"It can't be helped. Keine said that someone else is coming to teach today. We can't possibly act so lewd in front of outsiders, no matter what, right?" Daiyousei felt that no matter what they did in private, they couldn't act so recklessly in front of strangers. As they spoke, Keine's figure appeared at the entrance of the Terakoya, followed by a girl with long purple hair, slightly crumpled rabbit ears on her head, and a medicine bag slung over her back.
"Alright, everyone, this is the teacher I've found to help with your studies today. Reisen, I'm counting on you."
"Understood. But I can really only teach some basic and simple knowledge. Please don't have high expectations for me." Reisen Udongein Inaba, the requested teacher, felt that asking her to do this was too difficult. She would be much better at things like firearms knowledge or battlefield survival.
"It's fine. After all, I just hope these children can learn a bit more, and the simpler, the better." Keine didn't think children like Cirno could understand or learn very difficult material. The main goal was also to enrich Kars's knowledge base.
"That's good then." Reisen breathed a sigh of relief. She was only here for this one session. After simply teaching those things, she still had to go sell medicine.
"So, next, I'll briefly talk to you about some biology knowledge and how to identify some poisonous substances so you can avoid contact with them."
"That sounds like it won't be very useful…" Kars found the class a little dull. Neither the content being taught nor the things they needed to be mindful of interested him at all.
"You shouldn't say that, Kars." Keine saw Kars's reaction and stepped forward to lecture him, hoping he would listen attentively to the class.
"It's okay. It's indeed boring for children." Although Reisen understood Keine's desire for her students to learn more, on some level, none of the students here were human, so studying this kind of content wouldn't be of much use to them.
"Here, take this. Just behave and listen through this class. We can't let your teacher's good intentions go to waste, right?" Reisen took a piece of candy from her pocket and handed it to Kars. Faced with this method usually used to coax small children, Kars gave Reisen a nuanced look but didn't refuse her kindness. He accepted the candy and popped it into his mouth.
"Huh?" After the candy went into his mouth, Kars's eyes widened slightly. Seeing this, Reisen smiled.
"How is it? It tastes pretty good, right?"
"It tastes terrible. Not only is it a little bitter and astringent, but also… also… Ugh!"
Everyone stared blankly as Kars suddenly vomited a rainbow, and then collapsed on the ground, pale-faced. Keine and the others looked suspiciously at Reisen, whose expression had also turned panicked.
"You… you're so mean! Just because Kars didn't want to listen to your class! You poisoned him with a candy!" Cirno couldn't believe there was such a terrible person in the world. Even Keine wasn't this scary!
"N-no, no, no!! This is a misunderstanding! It's definitely a misunderstanding! How could I do something so heinous! That candy was originally meant for myself! How could it possibly…" As Reisen said this, she instantly realized the truth. A mischievous image of a black-haired Loli with a pair of rabbit ears flashed in her mind, grinning maliciously.
Undoubtedly, that candy had been tampered with by her. If it had been any other time, she would have eaten the candy herself, and the person lying on the ground would have been her. But now, because she gave it to Kars, he was the one suffering.
"First, we need to send him to Eientei for treatment!"
Regardless of the situation, the first thing to do was to seek medical attention. The reason she was always fine after being plotted against and poisoned was not only because she frequently tested medicines and had a tolerance for them, but also because most of the poisons aimed at her only caused her some discomfort.
However, if it were any other Youkai or human, it could very well be a fatal poison. Therefore, Reisen didn't hesitate and immediately picked up Kars and hurried to Eientei.
After running all the way to Eientei, Reisen urgently called out,
"Master! There's an emergency patient who needs urgent care!"
Following Reisen's call, Eirin Yagokoro, wearing a white lab coat and making potions, stepped out of the room. When she saw Kars in Reisen's arms, she somewhat understood the situation. Clearly, he had accidentally ingested her medicine and was experiencing an adverse reaction.
"I understand. Bring him inside." Eirin Yagokoro said.
The situation was not difficult to resolve. After Reisen put Kars on the bed, Eirin Yagokoro walked over with a syringe containing a carefully measured dose, ready to inject Kars. However, she noticed that an energy within Kars's body was already working to heal him.
This piqued Eirin Yagokoro's interest, and she began to observe.
"Master?" Reisen looked at Eirin Yagokoro, who had suddenly stopped the treatment, and was confused about why she paused.
"Don't worry. The child is fine now. I'm just observing the condition of his body. By the way, weren't you teaching a class? How did this happen?"
Seeing Eirin Yagokoro bring up the matter, Reisen sighed and explained the whole chain of events. Eirin Yagokoro shook her head helplessly.
"From now on, besides things you bought yourself, don't randomly give away anything you carry, understand?"
"Yes…"
