The Magician of Sound

Kai came out of the bath and found his sister in the living room, preparing tea for him.

"Have you calmed down?" Tasha smiled and waved her hand, asking him to take a seat. 

"Yeah. Thank you." Kai nodded as he took a sip on a warm tea. 

"Looking at your expression earlier, it feels like looking at me from a few years ago." Tasha smiled as she also took a seat beside him. "Do you remember that?"

Kai closed his eyes, sipped his tea, and nodded. "It\'s a few years ago when you killed humans for the first time. If I am not wrong, you can\'t even eat a tomato for a month."

"Haha… Right. Tomato… Mom and dad were worried at that time because it was too sudden. Luckily, that happens was only for a month, and I acted normal again. On the other hand, it\'s normal for you to have such an expression after leading such a big scale war." She gently smiled.

"Where are mom and dad?" Kai asked.

"Oh, they are shopping for daily necessities." 

Kai nodded, and the room fell into silence again. "Anyway, how about you take a bath first?"

"Ah. Alright." She nodded and left him alone, so he could think about it more, albeit she missed his intention.

Kai pulled out his communication device and searched for Ayaka\'s contact. "How are you doing?"

Sadly, the answer didn\'t come even after a few hours, so he could only retire to his bed.

…

Meanwhile, 

Ayaka was wearing plain white clothes, looking like a patient. After getting a lot of preparation from the professor, she was finally ready to take the fight. 

On the other side, Ria Ross brought many blood bags with her.

"... Professor, if I may ask, how many bags are you going to inject into my body?" Ayaka asked with a complicated expression.

"Ah. Don\'t worry. I am only planning to inject two bags inside. The rest are Human blood that is compatible with you."

"Human blood?" Ayaka was astounded. 

Ria pondered for a moment before saying, "I should explain it to you first. There are three possibilities for this experiment. First would be a success. The blood would fuse in your blood and stay dormant. It might be like instinct or whatever, but you would be able to control your blood, whether you want to activate them or not… or so what Kai told me. I didn\'t participate in the creation process of Pisces, Sagittarius, or Taurus, so I lack data."

"Meanwhile, the second possibility would be when you half succeeded. For this, I will describe the process itself.

"When I inject the blood into your body, the animal blood would become active and chip away your human blood. This will cause a reaction, and you would feel pain. This is why I want you to get used to the pain first.

"After all, you need to use your magic power to fight back. Kai could easily do this because of his unwavering will and his magic power, making this operation so easy. On the other hand, you are a princess that has been living comfortably for many years and only tried to shed your empty shell not long ago.

"At the same time, your magic power is quite high for a normal person, but still not comparable for the animal. You would find trouble in fighting the animal blood. In other words, the only way I can do to increase the chance is to make you used to the pain. This allows you to stay calm under the treatment because I will be injecting the blood into your body when you are awake.

"The animal blood would eat your magic power, blood, and organ before replacing it with its own, leading to the second and third possibilities. You will either die or turn into a half-magical beast. Dying is fine since you won\'t cause trouble, but if you turn into a magical beast, I would need to kill you. Well, Kai would probably hate me after that.

"Ah, if you are wondering what kind of half magical beast I am talking about. You wouldn\'t become a man\'s dream, such as ears and tail. Instead, you would look like a monster. It\'s literally half-magical beast half-human. Your hand might be human, but your feet might be animal and so on.

"That\'s why I am asking if you are ready for this? Have you gathered your resolve?" Ria Ross explained while preparing the blood bag and all equipment.

"I am ready," Ayaka answered without any hesitation. 

"One more thing I need to add. I won\'t inject any pain-killer to you because you need a natural body without having unique substances in your body."

"Understood. I will do anything as you say." Ayaka nodded before bowing her head.

Ria paused for a second. "Alright. The blood that I will inject you is from Wildebeest, specifically Blue Wildebeest. This species can be considered as one of the fastest animals on the land. In terms of speed alone, it is equal to Lion… which is Kai\'s magical beast. 

"Of course, a power like this sounds too good to be true. Kai\'s lion blood is hungry for prey… if he continuously used that power, his instinct would slowly take over him and attack his own teammates. That\'s why he never uses it extensively.

"As for the Pisces and Sagittarius, I am not really sure, but from what I saw, Pisces lost his attacking ability. In other words, he is only a weak person who can only heal people. On the other hand, I am not very clear about the latter one, so I won\'t spread any misinformation."

"Do you have a question about this?" Ria Ross asked before finishing her preparation.

"No. I don\'t have one. I will leave all of the important things to you, Professor." Ayaka paused for a moment before glancing at her with hesitation. "Actually, I have one request…"

"What? I don\'t like having to fulfill other requests… Since you are Kai\'s woman, then I would allow it." Ria nodded.

"This is not a complicated request. I just want to ask if this operation ends up a failure. Can you hide it from Kai? And tell my family that I have died because I was reckless and charged at the magical beasts alone?"

"Oi Girl. Let me tell you one thing, I hate to promise someone something, but I didn\'t like how you leave it up to fate more. Come on, if you only have this little determination, I will just cancel this and be done with you." Ria shrugged. "Listen, I have broken my promise with Kai because of you, so rather than having that weak will, it\'s better for you to say you are going to succeed. Alright, since you have no other question, I will begin the operation."

"Yes, please do." Ayaka sighed as she looked at the blood slowly flowing before entering her body slowly.

"The first blood bag is still normal. I will start pumping the second one before replenishing your blood." 

Ayaka nodded as she sweated profusely. She began experiencing pain not long after the blood came inside. It was like something sucking her blood and spread the pain. Luckily, the pain was still bearable as she didn\'t let out a single sound.

As soon as the second blood bag was emptied, Ayaka let out an uncomfortable moan. She started suppressing the blood within her body.

"The process is going well. However, be ready as the real fight would be when the blood enters your organs. It would be a battle of endurance, so I hope you can succeed. I hate funerals." Ria shrugged as she continued monitoring Ayaka\'s condition.

Ayaka had no time to deal with her joke, so she only closed her eyes to grasp a better focus on her magic power.

"I can do this." She muttered to herself. Unfortunately, the pain started growing even further, jolting his body and mind at the same time. Even though Ayaka was accustomed to the pain to a certain extent, the pain that accumulated in this operation was beyond her imagination. 

"Argh!" Her eyes opened wide as she let out a scream.

"This is going to be troublesome… Blood percentage is going down while the heart rate is also going down." Ria Ross quickly grabbed another bag to inject it into Ayaka. "Don\'t lose to the fight… Haiz, I should kill her two to three hundred times first before injecting this."

"Argh!" Ayaka couldn\'t hold it anymore. It wasn\'t just her blood that was swallowed by the magical beast blood. Her organ started getting infected and released a more painful wave to her nerve system. 

The pain continued to her heart, liver, and so on. Her body was covered with pain as her body started shaking uncontrollably.

Her eyes started looking like a magical beast faster than Ria expected. This would only happen if Ayaka couldn\'t endure it anymore.

"What should I do? The only one who can fight the blood is herself…" Ria Ross pondered for a moment without letting all information escape unnoticed.

"What am I going to with this?" She gritted her teeth before looking around. "If this continues, then the only result would be a failure… but what should I do?"

Ria Ross looked around, hoping for enlightenment. 

Whether it was fortunate or unfortunate, the answer came in the form of blood. She looked at a cupboard with many blood bags inside it.

She appeared instantly in front of the cupboard and opened the lid. These blood bags were her personal collections. 

Ria was a bit adamant about using this, but she gritted her teeth. She didn\'t have any choice other than grabbing the blood bag and injecting it into Ayaka\'s body.
