A few hours later,

Kai and the others had recovered and only needed to wait until their magic power got recovered. At that time, Sofia decided to return to their hotel since Nathan had lifted the evacuation order, letting all people return to their activity. Unfortunately, the beach was closed for cleaning reasons, and they would only open it the day after.

Sitting inside the hospital room with the others, Kai presented a question. "Are we going to go with the schedule?"

Michelle thought for a moment and nodded. "There is nothing much to do in this place, especially since we have explored the city. I think it's better to buy some souvenirs for your family before we enjoy the beach on the last day. But it might be a bit stuffed tomorrow, considering most people will probably do the same."

"It's just one day." Tasha shrugged and stretched her hand lazily.

The Eagle group also had no problem with the suggestion as they thought it was nice to buy some souvenirs for their families.

"It's decided then." Kai nodded with a smile.

"That's right. I have meant to ask this. What is that magic from earlier?" Tasha asked.

"Hmm?" Kai thought for a moment.

"We will take our leave now." Isabelle suddenly decided to return because Kai was going to explain something important. Although Kai didn't mind them hearing about rewarding them for their efforts, he didn't stop them either.

The Eagle Group followed Isabelle and left the room.

Kai sighed and explained. "It's simply magic that I created after combining three magic. Sound Insulation Magic, Supersonic Assassin, and Oscillation Shield…"

Kai started explaining how the thing worked. As expected, the Eagle Group was silent, hearing his explanation. They realized that Kai could do this because his ears allowed him to understand the sound better. Unfortunately, Kai couldn't explain it scientifically and relied on normal science.

"That is good magic… I can see a few variations already. I think this will be your main magic in the future." Michelle thought for a moment.

"Yeah. First of all, I can increase one's speed and direct some maneuver as I wish. And this is not limited to a human. It can be used to an object, like a bullet or even a normal rock. By boosting them with this magic as I throw them, I can launch them to something close to a bullet."

"How about asking Isabelle to train your shooting ability?" Ayaka suggested. "She is the number one shooter in the academy, right?"

"No! It's me!" Tasha pouted. "If you want to train, I can teach you everything about the shooting. An arrow isn't really different from a bullet, and the fighting style that you have in mind is closer to me, right?"

"Yeah… At the very least, I won't fight like Sir Nathan…" Kai confirmed together with a nod.

They remembered that Nathan's weapons were a sword and a gun. Ayaka then sighed. "I am sorry for misunderstanding it then."

"It's fine. I will just talk about my magic rather than this depressing topic." Kai tried to change the topic.

Tasha supported his argument. "That's right. How about explaining how magic works? Maybe we can help you or something."

"Hmm… I can only use this because I have enough magic power after getting that device." Kai thought for a moment. "As you already know, my magic power is sealed inside Tasha's body. This thing isn't really explained in school, so I think it's good additional knowledge.

"First of all, let's say that we have a bucket and a cup. These two can represent my and Tasha's magic vessel, or so what Teacher told me. There is also another thing… Just say it's a big bathtub, filled with water(magic). If you get the water with a bucket and a cup, which one do you think will be able to get more? It's the bucket, right? This will be my condition when I have my whole magic power. When my magic power is sealed inside Tasha, it doesn't mean she will gain this bucket. She only gets the water alone. In other words, the bathtub might be filled with water, but she can only draw it with the cup.

"That's why you needed to use a few magic circles to complete your Lightning Magic, right?" Kai smiled, looking at Tasha as if he knew everything.

Tasha nodded. "That's right. I don't know about this theory though. I only know that I can't create everything in a single magic circle, so I choose to make it with five. I think my Teleportation also has the same condition."

"Yeah. I have explained that to you, but not at this point. Well, this is Teacher's research anyway…" Kai nodded. "I will continue my case then. First of all, I don't have much magic power. You can imagine that I have this bathtub, but the water only filled ten percent of it. Then I try to draw the water with that bucket, do you think I can get a bucket of water? No? That's my current condition.

"I can only draw, maybe… thirty percent of the bucket. This won't be enough to fuel up to three magic simultaneously, so I can't use my Sound Blast this whole time despite having the concept to use it. It is different now that I have twenty percent. You can say that I can fill a maximum of eighty percent of the bucket if I work hard to force the water inside.

"You remember that I have once said thirty percent of my original magic power is enough, right? This is the reason." Kai nodded, pausing for a moment. "I can do whatever I want with this thirty percent of magic power, so I will wait until Teacher can make me one."

"If you beg her, you might get it faster, you know…" Michelle teased him.

Kai smiled, shaking his head helplessly. "I don't want to burden her more than necessary. As much as I hate to say it, I have owed that person too much."

"I see. Is this also the concept of making that device of yours?" Michelle asked.

"Most likely. Teacher doesn't really talk much about this, and I think I shouldn't ask as well."

"In any case, I feel that this concept will benefit us… I am grateful for that. I will ask Professor Ria whether I can use this concept next time for myself, of course," Michelle said. Ayaka nodded in agreement.

On the other hand, Evan stayed silent, wondering whether he could use it or not. Unfortunately, he didn't really have an attack ability, so he decided to focus on his hand-to-hand combat rather than his magic. It's only for self-defense to prevent this type of accident from happening again.

Kai smiled gently. "It's fine to use it, I guess. I will also confirm it with Teacher and let you guys know later."

"Since we have finished discussing this, I think it's time for us to go back. What will you do, Evan?" Michelle asked, glancing at Evan.

"I think I will help the soldiers since I don't contribute much on the battlefield." Evan nodded, planning to go to the military base.

"I will have someone to accompany you to—!" Before Kai finished, Evan rejected the idea.

"Don't worry. I will call Eagle Group later for this. Captain and the others have truly fought a tough battle, so I think you should rest first."

Michelle grinned as she teased. "This is what he wanted to say. I want my girlfriend to escort me, so you normies need to go back right now!"

"I see…" Seeing this, Kai decided to play along and immediately brought the others with a sad expression.

"Wait! What? No!" Evan tried to correct them, but these three words were the only ones he could utter before Kai and the others left the room.

When they returned to the hotel, Kai took a bath first since the girls went right after.

"Ah! That nice…"

"Yeah."

"It must be because of our fatigue. That war was hard-fought and the most challenging."

The three girls chuckled as they walked toward their bedroom, only to find Kai already falling asleep. They looked at each other and smiled, knowing that the one who had the most burden was Kai.

"Let's go outside first to enjoy the night breeze… I also want to talk to you two." Suddenly, Tasha invited them with a grim expression.

There was no need to say it. Michelle and Ayaka turned serious, realizing what she wanted to talk about. They followed Tasha to the balcony.

"Judging from your expression, I think I don't need to tell you this, right?"

"Of course. Despite everything that happened, I was the most useless one in our group. Unlike you who decided to release your power or Ayaka who held the water elemental, I didn't have any achievement in this battle other than getting beaten up by that Eru," Michelle said harshly to herself.

"I also didn't do much. My Fire was utterly useless against that thing." Ayaka sighed before comforting Michelle. "While you had commanded us brilliantly."

"Don't say that. I might hate myself even more… If everything can be resolved by commanding a few people, I would not need this strength. Sigh. I was the useless one just because I couldn't rely on my power too much during the day…" Michelle took a deep breath and clenched her fists. "Don't worry. I know what to do…"

"You are not going to be a Zodiac, right?" Tasha squinted her eyes.

Michelle glanced at her for a few seconds before shaking her head. "No. I have a plan for this. I will make it before another big battle comes."

Ayaka also closed her eyes, knowing that she needed to do something to keep up with their progress.

Tasha nodded before she said while looking at the sea. "I will release my limiter soon… I think we have enough strength to protect ourselves now…"

Ayaka was clueless about this, but Michelle perfectly understood what she meant. She asked with a shocked expression. "Are you serious?"
