His battle with both Kou and the Wiseman was short, or rather, it only took him a few moments to end both of them and what took his time was just the time Kou took to revive Wiseman and also the time Kou laughed, thinking that he had won.
However, their battle ended so shortly, and Haru returned quickly together with Nina, who also followed him since she didn't have any place to go and she had just awoken, so she didn't know much about what had happened when she was sealed together with Wiseman and who Haru was?
"I'm going to take a bath. You can wait in the living room," Haru said.
"Wait! Let me go with you!" Nina quickly said.
"......" Haru looked at Nina strangely.
"What? Are you shy?" Nina asked with a smile.
"......."
Haru looked at Nina and knew that based on her age, she could be called his grandma, but looking at her size, which wasn't much different from an action figure, he felt a bit complicated. "Well, I don't mind."
Both of them went to his hot spring and rested there lazily.
"How comfortable..." Nina said with a sigh, resting her body on the small wooden basket that was prepared by Haru.
"Right?" Haru also nodded, but inside, he was thinking about the alchemist knowledge that he had just stolen from both Kou and the Wiseman.
Nina looked at Haru and had to admit that this guy was so handsome. She was wondering whether she could return to her normal body size that way... Cough! Cough!
"By the way, what's your name?" Nina asked since she didn't know who Haru's name was or rather she didn't know anything about him.
"My name is Kasugano Haruka." Haru looked at Nina and said, "You're Nina Adelard, the Great Alchemist, right?"
"That's right!" Nina nodded and felt a bit proud since her name was known by Haru. She then looked at Haru, and truth to be told, she was curious who he was, but she also didn't want to be rude too much, especially when he was so strong. Even though she hid it well, she was afraid that she might disappear just like Kou and Wiseman, but she had to admit that even she was afraid, she also felt comfortable and his face was so handsome...
"If you have something to ask, then just ask, but I'll also ask you a question." Haru looked at Nina and said, "Equivalent exchange, right?" Based on the story that he had watched in the past, the principle of the alchemist was an equivalent exchange. Not sure if it was similar in this world, though.
Haru might have learned various magic in this world, but he had never put his eyes on the alchemist since it was so rare to see an alchemist, and there was only a limited number of alchemists in this world. Their knowledge was only circulated to a limited number of people, and he was also too lazy to get them since he didn't know how strong it was until he saw how Kou's memory.
Haru had to admit that an alchemist was strong, and he wanted to learn it. He had gotten the knowledge of both Wiseman and Kou, but the Great Alchemist was right in front of him, and wasn't it too wasteful not to learn something from her?
As for stealing Nina's knowledge, Haru didn't have that idea since Nina was a beautiful woman.
"Oh!" Nina was surprised that Haru knew the principle of the alchemist, so she nodded with a smile and asked, "You want me to teach you the alchemist?"
"Is it so easy to guess?" Haru asked.
"Of course." Nina nodded with a smile and felt that it was normal for Haru to know her instantly when he saw her since he was interested in alchemy. "I don't mind teaching you, but can I ask you a lot of questions?"
"Why not?" Haru nodded. "What do you want to ask, Nina?" As for calling Nina his "master" or "teacher," he felt that it was a bit too much.
Nina also didn't care, but she asked, "I have been sleeping for the past few years. Can you tell me more about what has happened in this world?" There were a lot of questions that Nina wanted to ask, but first, she needed to know everything about this world since she had been sleeping for a long time.
Haru didn't mind and started to tell her about what had happened in this world recently.
When Nina asked, Haru answered, it was as simple as that.
"So, can you tell me who you are now? Besides your name, I don't know much about you." Nina smiled, looking curiously at Haru, and said, "You'll become my student, right?"
Haru raised his eyebrow, then said, "Genius, billionaire, philanthropist, and the fourth primogenitor." He didn't add the playboy to his introduction since he didn't need to.
"........"
However, Nina was dumbfounded by her introduction, especially the last one. "Fo - Fourth primogenitor? You?"
".........."
"I'm." Haru nodded and said, "It might be only a few months that I have become one, but I'm the fourth primogenitor."
"..........."
"You're a vampire?" Nina was stunned, then asked, "Then why do you want to learn an alchemist? Don't you have a Vassal Beast? Wait? Did I hear that it has been a few months since you have become the fourth primogenitor?" She then observed Haru up and down and felt that if this guy was the fourth primogenitor, then his name should be loud and popular, considering how handsome he was and how well-done he was at his nether region, but she had never heard of him in the past. She also had never heard that someone could become a fourth primogenitor, and there were a lot of questions on her head, and it made her uncomfortable that she was afraid that her question might make him angry.
'Ugh...'
Looking at Nina's expression, Haru had to admit that he was cute, but it didn't mean that he was going to tell her everything, considering it had only been a short time since they met each other and he also didn't really want to tell more about his information.
As for whether Nina wouldn't teach him alchemy or not, Haru didn't need to worry since he was sure that Nina would teach him.
"Which is why I'm not a vampire, and I'm a human," Haru said.
"Human..." Nina was dumbfounded.
"Well, I won't tell you much about how I have become a fourth primogenitor, and now, can I ask you a question?" Haru asked.
"Sure." Nina nodded without hesitation. There were still a lot of questions in her heart, but she held herself since there was a lot of chance that both of them could talk to each other and he would become his student, so there was no need to be in a hurry, right?
"Nina, do you know about Schneewalzer Lance?" Haru asked.
"Oh, the strongest weapon of the Lion King Organization, right? Why do you ask that?" Nina asked curiously, wondering why Haru asked about Schneewalzer Lance.
"Can you tell me more about that lance?" Haru asked since he knew that sooner or later that lance would cause trouble for Himeragi, and before that, he hoped that he could solve that trouble for her.
