In the morning, Haru followed Yukina to school since she hadn't finished her transfer procedures. Both of them walked together and entered the school on the summer break.
Haru looked around and could see how empty the school was. The only ones who were in the school were the staff, the teachers, and some students who got bad scores during the first semester and needed to do remedial.
"Sorry for troubling you, Senpai," Himeragi said in an apologetic tone since she felt like she had troubled him most of the time. Even though she had said that she would become a maid, the one who cleaned up the house was mostly a robot, and she didn't have time to show her ability.
"It's alright. You have cooked breakfast earlier, right?" Haru said.
"But..." Himeragi might have cooked the breakfast before, but the taste wasn't as good as the one that was cooked by him.
"You don't need to think too much. Your cooking is very delicious too," Haru said.
"Yes, but..." Himeragi thought for a while and suddenly asked. "Say, Senpai."
"Hmm?"
"Since you have become a fourth primogenitor, do you have an urge to drink blood?" Himeragi suddenly asked.
"What's wrong so suddenly?" Haru asked weirdly.
"I... I mean... if you want, you can drink my blood..." Himeragi said with a red face.
"...."
Haru let out a sigh and knocked Himeragi's head.
"Ouch!" Himeragi held her head in pain.
"I've told you before that I'm a human, right? I don't drink blood," Haru said.
"But..." Himeragi looked at Haru with teary eyes since she wanted to do something for him.
"If you want me to help you, then you shouldn't follow me when I go for a date," Haru said.
"That's something that I can't do! I need to follow you everywhere, Senpai!" Himeragi said without hesitation.
"..." Haru realized that this girl was really troublesome.
Himeragi then looked at Haru then asked, "Um, Senpai." In truth, she wanted to ask who his girlfriend was, but she felt a bit hesitant to ask.
"What's wrong?" Haru asked.
"Um..." Himeragi wanted to ask him, but suddenly someone called his name out.
"Haru, what are you doing here?"
Haru and Himeragi looked up and saw Natsuki was there.
"Natsuki-chan, you're not on holiday?" Haru asked.
"There's still something that I need to do as a teacher, but what are you doing here with a middle school student? Are you going to make her into your girlfriend too?" Natsuki asked while staring at Himeragi.
Himeragi blushed and quickly hid behind Haru. "Se - Senpai..."
"Well, Himeragi, she's Minamiya Natsuki and she's my teacher. I'll talk with her for a bit so you should take care of your transfer procedure first. If you are done with your transfer procedure, just call me, so I'll know," Haru said.
"Yes!" Himeragi's face was very red, and she quickly ran away since she somehow understood why Haru decided to let her live in his house.
"So, who is she?" Natsuki asked.
"You're jealous, Natsuki-chan?" Haru asked with a smile.
Natsuki snorted and said, "You're such a narcissist!"
"Well, let's talk in your room. You must have something to ask me too, right?" Haru said.
Natsuki looked at Haru for a moment and sighed. "If only you're not so lustful."
"If I'm not so lustful, then a lot of people will be worried about me, right?" Haru said.
"...." Natsuki couldn't deny it, but she was wondering whether his lustful act was real or fake. It might be a weakness that he decided to show, which somehow made her sigh since this guy was too strong. She didn't have the ability to do anything against him, nor did she plan to. She sighed and said, "Well, let's talk in my room first. The summer in the Itogami Island is very hot, after all."
---
Inside Natsuki's room, Haru sat down on the chair with a relaxed expression. "Natsuki-chan, do you have ice tea?"
"....." Natsuki.
"This is my room, not your house," Natsuki said speechlessly.
"Well, really, what poor hospitality," Haru said with a sigh.
"There's hot tea here. Do you want to drink it?" Natsuki asked. "Or should I pour it on the top of your head so it'll cool you down?"
"...." Haru.
"Okay, okay, I'll stop joking around. What do you to ask?" Haru asked.
"Well, let's set this matter aside first. Who the hell is that middle school student?" Natsuki asked with a frown.
"You're not jealous, right?" Haru asked.
"I'm jealous!" Natsuki said without hesitation.
"....."
Haru blinked his eyes and said, "I didn't expect you to be so honest, but that girl is an observer from the Lion King Organization."
"Lion King Organization? What the hell does that organization want to do with you? More importantly, how did they know you with all of your disguises?" Natsuki knew that if Haru didn't want let anyone know, no one would know about his identity, which was why, unlike the other three primogenitors, she knew that he was even dangerous. She thought for a bit and asked, "Don't tell me that you think that she's cute, so you let her notice you?"
"..." Haru.
Haru looked at Natsuki and said, "Natsuki-chan being too mysterious isn't all good."
"Huh? Why?" Natsuki asked with some confusion since she felt that staying unknown was good for him since no one would bother him.
"Being unknown means I'm scared, but you should know that I'm not scared, right? You don't need to worry. I'm stronger than you think. More importantly, you have something important that you want to ask me, right? I'll help you," Haru said.
Natsuki looked at Haru with a complicated gaze, and somehow she was both grateful and curious. She was grateful since she thought that he had joined the school and lived as a normal person because of her, and at the same time, she was curious at how strong he was. The only power that she knew was his EMP ability, which destroyed the electronic device and caused a power outage in a huge area. His other ability was his seal magic, which made him able to seal anything.
Anyway, Natsuki thought that Haru decided to go to the school because of her, which was why she had a soft spot for him.
"Well, since you need to decide to help, do you know anything about these?" Natsuki asked while showing four documents on the table.
Haru looked at the documents curiously and asked, "Devils? And four of them? Hmm... all of them are in a coma, huh?"
"Do you know anything?" Natsuki asked.
Haru didn't answer Natsuki's question first and looked at the data of the four devils that were shown on the table. He could see that all of them were in a coma, and all of their energies were absorbed by something or someone. "Their energies were absorbed?"
"That's right. What do you think?" Natsuki asked.
"Well, these things are more likely to be done by someone who hated a devil, someone like from the church or something. As for why their energies were absorbed, it's more likely that this someone from the church might have a helper, and this helper needs the energy from those devils. Lastly, this incident is more likely to be done by two people," Haru said simply.
"Hmm..." Natsuki's eyes became serious, but then she asked, "But why did someone from the church? Could it be other demons or someone who hates a demon? And why is it only two people? Shouldn't there be more people?"
Haru sighed and said, "You know, the Island Guard is simply useless. What are they doing in this situation, letting an outsider solve their problem? What are they being paid for?" He felt that he had become Conan somehow, but he wasn't Conan, and he wouldn't solve the case because of a hobby.
"....." Natsuki couldn't say anything in refute.
"What about the cameras on the island? Check all of the cameras first before you ask me about this problem. You have the latest technology. What's the use of that technology for?" Haru asked speechlessly.
Natsuki let out a sigh and said, "That's true. I wonder why they're being paid for." She then looked at Haru and asked, "Still, let's put this matter aside. Are you letting the Lion King Organization put an observer on you?" She knew that many observers hiding in the dark had been taken out by Haru directly, and as for where they were, she wasn't sure, and she didn't really care much, but she wondered why he let Himeragi stay beside him.
"Well, don't tell her. I think she's a bit stupid," Haru said.
"....." Natsuki.
"She's so stupidly cute, so I let her stay beside me, and I don't think that the Lion King Organization sent her to become my observer," Haru said.
"Then why did they send her for?" Natsuki asked with a frown.
"That's what I want to know too, which is why I let her stay on my side, and have you seen her weapon that she put on the guitar case before?" Haru asked.
"That's a weapon?!" Natsuki was dumbfounded.
"There's a weapon inside, but that's not the point here. The point is to use the power of that weapon, she needs to sacrifice something, and if I let her go, she might...." Haru shook his head and said, "Well, her situation is a bit similar to yours."
"...." Natsuki.
Haru looked at Natsuki and asked, "When you come out from that legendary prison, why don't we have a date, Natsuki-chan?"
"....." Natsuki.
Natsuki took a deep breath, but the door was knocked on.
"Senpai, are you there?"
"...."
"What a time." Haru shook his head and stood up. "Well, Natsuki-chan, if you think that you're ready, just tell me, you're cute this way, but I still want to see the real you." He waved his hand and left. "Bye, Natsuki-chan."
Natsuki looked at his back, then said softly, "Bye, Haru." She also wanted to come out and show her real body. She wanted to trust him, but at the same time, she was hesitant. Her feelings were contradictory, but well, she quickly shook her head since it felt a bit cheaper to give herself like this so easily since she wanted him to treasure her dearly.
