Kars then led Daiyousei to find Cirno at Patchouli's location. Seeing her, Daiyousei immediately ran over.
"Honestly! Cirno-chan, why did you run off like that! You left me all alone there!" Daiyousei looked at Cirno with a hint of resentment. If Cirno hadn't left her, she wouldn't have been alone when she stumbled upon that scene.
"Because I couldn't find any magic books I could read, so I went somewhere else. As for you, I accidentally forgot you." Cirno explained the reason, and Daiyousei, completely exasperated that Cirno had forgotten her, started scolding her and hitting her while calling her an idiot.
"Cirno-chan, should we leave now?" Now that she had found Cirno, Daiyousei wanted to get out of there. Staying any longer made her nervous, especially with Koakuma nearby.
"But I still want to find a magic book I can learn from." Cirno, however, wasn't ready to leave, still wanting to search.
"It's clear that none of the magic books here are suitable for you. What I gave you just now was already the fundamentals of magic, and you couldn't even understand that." Patchouli stated the fact. She had completely determined that with Cirno's brain, learning magic was simply impossible. "Huh? Is there really no magic book that teaches itself upon opening?"
"How could such a thing exist in this world? Even I can't create a magic book like that. Kars, please hurry and take her away. Otherwise, I can't continue writing my magic." Thoroughly exasperated by Cirno's wishful thinking, Patchouli urged Kars to take Cirno away.
"Alright." Hearing Patchouli, Kars walked over to Cirno and took her hand. "Cirno, let's go now. It's no big deal if you didn't learn anything; it won't affect you."
"Mhm! Lord Cirno's strength is already very impressive. Even without magic, it won't affect me at all." Cirno smiled at this, then left the Great Library with Daiyousei, following Kars.
"You're finally out. Cirno, well? Did you learn any magic?" Lyrica, waiting outside, asked Cirno as the three emerged.
"Lord Cirno's strength means I don't need to learn magic."
"Oh, so you didn't learn anything. I knew it." Lyrica had expected Cirno's answer. If Cirno had managed to learn magic, that would have been the truly incredible thing—it might even qualify as an incident.
"But Daiyousei, what's wrong with you?" Mystia looked at Daiyousei, who looked relieved after coming out. She couldn't understand why she looked like that, as if there was something scary inside. Furthermore, her legs had been constantly rubbing together since they came out.
"N-Nothing." Daiyousei quickly shook her head, claiming nothing was wrong. Now that she had calmed down, the wet, sticky feeling of her panties clinging to her made her feel extremely uncomfortable, and she desperately wanted to change them.
"Is that so?" Mystia was still puzzled, but since Daiyousei said so, she figured it must be fine. Kars also looked at Daiyousei's actions, having seen that movement on Koakuma. He wondered why Daiyousei was doing that.
Kars's gaze made Daiyousei nervous. She worried he might have noticed something and realized she had peeked at him and Koakuma.
"Cirno-chan, let's go back. We've played enough." Feeling that the longer they stayed, the more likely she was to be discovered, Daiyousei wanted to urge Cirno to leave. She feared Kars would find out now, or what would happen if Koakuma told him.
"Alright then. Kars, we'll head back now!" Seeing Daiyousei's urgency, Cirno didn't refuse and said goodbye to Kars, preparing to go home.
"Then we'll go too." Lyrica, seeing Cirno and Daiyousei leaving, also stood up.
"Come again next time." Kars nodded and bid farewell to the group, watching them leave the Scarlet Devil Mansion.
"Huh? Daiyousei, why are your panties wet? Ah! Does that mean you were in such a hurry to come back because you peed your pants?" After returning to the fairy house by the Misty Lake, Cirno saw the pair of panties Daiyousei had changed out of and immediately thought she understood why Daiyousei had rushed back.
"I did not pee my pants!" Daiyousei retorted, her face flushed crimson.
"Then why are they wet?" Daiyousei had no way to answer this question. She didn't know how to explain it, and as for telling Cirno what she saw—she simply couldn't. Not only was the sight too embarrassing, but Cirno wouldn't understand it even if she did. Cirno scratched her head, looking at the sulking and emotionally distressed Daiyousei.
"Alright, alright, it's nothing serious. Let's go outside and play now!" Cirno grabbed the silent Daiyousei and rushed out, believing that playing a little might help Daiyousei recover. Cirno had a lot of fun throughout the outing, and Daiyousei's mood was gradually lifted by Cirno's influence, slowly beginning to recover.
That night, Daiyousei had a dream. She found herself alone in the Scarlet Devil Mansion's Great Library, unable to find her way out no matter where she walked. Suddenly, a familiar figure flashed by in the distance.
"Cirno-chan!" Daiyousei recognized Cirno and immediately chased after her. As she rounded a corner, she once again stumbled upon that unforgettable scene in the Great Library: Koakuma and Kars together. This time, she didn't immediately hide behind a bookshelf but stood motionless, watching the two of them, unable to tear her gaze away, even though her face was burning red.
At that moment, a second Koakuma appeared behind Daiyousei, biting her earlobe while running her hands over her body. Daiyousei's body trembled, and she struggled slightly, but her weak resistance was futile. As Koakuma's hand slowly slid down into her skirt, Daiyousei woke up.
