Unagi was a specialist in using booby traps or mechanisms to injure or kill. He carefully scanned the tunnel's ceiling before examining the three bodies lying beneath it.

"Judging by the position of the bodies that were exposed to the blasts at full, it seems something is stopping and distracting them."

Unagi picked up a broken buckshot lying on the floor before continuing, "The fatal injuries sustained by Stuart and his two colleagues were not caused by shockwave or heatwave, but by buckshot bursts that caused a much larger wound cavity compared to hollow-point projectiles."

Keizawa nodded before saying, "It seems we are not dealing with Jean Hateur, but an ex-commando specializing in combat engineering, and we don't know his skills set."

"Shieeeet!" Irene cursed before closing her eyes and clenching her fists hard.

Keizawa then let out a deep breath before turning his head towards Unagi. "Properly bury them, I will write letters to their families myself."

"Roger."

Unagi immediately took out his cellphone and called several numbers.

Stuart and his two colleagues were not part of the organization Keizawa led. However, as the manager of the Kiotto Kafe, Keizawa had responsibility to ensure that mercenaries who entered Nichiko did not disturb public order, and on the other hand the authorities did not interfere with the mercenaries' vacation.

Keizawa also added a custom of writing letters to the fallen mercenary's family, if when they were at Nichiko they didn't cause an uproar in public. It was said that this little custom earned Keizawa great respect from the mercenaries who visited Nichiko.

With a long sigh Keizawa muttered inwardly, 'Stuart had two ex-wives and three children, while his colleagues are brothers who left a father. I must write a letter to them as soon as possible.'

This afternoon, Aizawa was dumbfounded because Hide suddenly returned home with curry rice from Tohru Ramen for her. Not long after that, Hide told her to stay well at home and then left again with a full-packed backpack and waist bag.

Aizawa cheerfully obeyed Hide's words. After having lunch with curried rice from Tohru Ramen, she then continued her activities like any other day, doing school work and studying until it was time to take a bath.

However, when the sun set and Hide had not returned, Aizawa started to get anxious, restless, and began to wonder if his brother left her and would never come back.

Previously, for more than two years every afternoon Aizawa had to close the curtain and turn on the lights in the whole house alone. Considering that Hide would only return home shortly before dinner time arrived.

However, during the last few days, Aizawa didn't have to do this anymore because Hide was the one who was going to close the curtains and turn on the lights all over the house. Therefore, when Aizawa had to go back to a routine that reminded her of the lonely days she had been through, she naturally sobbed as she wondered what mistake she had made so Hide left her.

Luckily Aizawa didn't have to wait too long, let alone Hide panicked as soon as he saw Aizawa sitting and sobbing near the door. Hide immediately carried Aizawa, and after seeing the expression on Hide's face, Aizawa instantly realized that his brother would never leave her.

After calming Aizawa down, Hide then shifted his younger sister's mood by asking her to order a pizza for dinner.

Aizawa cheerfully received the smartphone and the money Hide gave her, then immediately looked for references on how to order pizza online. Not long after Hide finished his bath, the pizza ordered by Aizawa arrived and dinner began immediately.

Long ago, Aizawa asked Hide to buy her a pizza after she saw a pizza ad on the tv that seemed super yummy, but Hide replied that pizza was not good for growing girls.

However, when Aizawa reminded Hide that pizza was not good for growing girls, Hide said that pizza which was not good for growing girls had been prohibited from circulating, and all the pizza currently circulating was much tastier and also good for growing girls.

'Whoah... Big Bro wasn't lying. Pizza in circulation right now is super yummy.'

Cheerfully, Aizawa gulped down a large bite of pizza topped with bacon, mushroom, and had sausage crust.

Seeing Aizawa enjoying the pizza with a content expression, Hide smiled broadly.

"Aizawa, is this pizza delicious?"

"Mhm... this pizza is super yummy."

"Then you should thank Big Bro by kissing and hugging Big Bro tightly."

"U-um... but Mommy said girls should not kiss and hug carelessly to become a perfect bride."

"Don't worry, that rule doesn't apply to Big Bro."

"Really?"

Aizawa tilted her head while Hide nodded firmly. Not long after that, Aizawa put the pizza slice in her hand before kissing Hide's cheek and hugged him tightly.

Without wasting time Hide kissed back Aizawa on the cheek and of course, also hugged her tightly. One little thing that in his previous life he could only imagine and dream of every night, while his heart was filled with regret and bitterness.

'In this life, I will make sure that happiness will always be with you.'

Hide murmured while desperately trying to hold back his tears.

Today was Aizawa's first day to study at Kitaro Music School, and although Kitaro provided a shuttle service, in the first-week Hide chose to take Aizawa and pick her up directly. In addition, he also intended to bring Aizawa to thank the subway officer who took her to the Kitaro Music School a few days before.

Hide and Aizawa bowed deeply, while Takeshi, the subway officer who took Aizawa to the Kitaro Music School, scratched the back of his head awkwardly.

"Well, this is not necessary. My first child is only four years old. While My wife is pregnant with our second child. So it's natural that I don't have the heart to see such a cute girl ride the subway alone."

"Uncle Takeshi, please accept this. These little gifts are nothing compared to the kindness you have shown Aizawa."

Still bowing, Hide handed Takeshi a parcel of pickle peaches which Takeshi refused. At the same time, Aizawa followed Hide by handing him a parcel filled with assorted chocolate.

Seeing the two children didn't seem like they would give up until he received the gifts, Takeshi finally received two parcels in front of him.

"Thank you, you two sure know how to make an adult like me flattered."

As soon as Takeshi received the parcel, relief immediately appeared on Hide's face. He then bowed deeply once more before saying goodbye.

Under Takeshi's gaze, Hide led Aizawa over to the subway that would take them to the south side of Nichiko. Carefully, Hide took Aizawa as if she was the most precious treasure in this world, while occasionally Aizawa would turn to Hide and smile broadly.

'Why does he look more like a father than a brother.'

Takeshi looked at Hide in amazement, just before he and Aizawa disappeared behind the subway door.

When Kaede Sensei found out that Hide and Aizawa's father was a senior programmer at an international game developer, she immediately asked Hide if his father could help Kitaro Music School create a student archiving program.

Without a second thought Hide agreed to Kaede Sensei's request. It's just that he was the one who would make the archiving program.

At first, Kaede Sensei doubted Hide's ability, but Hide cleverly issued a deadly move for a free program complete with a maintenance packet as long as Aizawa studied at the Kitaro Music School.

An archiving program or what was often called the Library Software was not a complicated program. The basic scripts were even available online, so Hide didn't need to build it from scratch.

Hide was also quite familiar with the Library Software. When he was in 7th grade he had succeeded in making a cashier program based on Library Software, and Emily managed to sell it for 100 Dillar or 10,000 Ren to minimarts, cafes, and several shops whose owners she knew very well.

It only took four hours before the prototype of archiving program was ready for data input.

Kaede Sensei looked at the black and white table on the screen before turning to Hide.

"Can we really start entering student data into the computer today?"

"Yes, meanwhile I will work on the program display so that in the future the staff will be more comfortable at work."

Kaede Sensei smiled broadly before saying, "Hide, we do not need an elegant or beautiful appearance. As long as we can access files quickly, that is more than enough."

"Don't worry Sensei, the part I enjoy the most is the making of graphic designs for displays. Also, I will assist in the data input process while checking for bugs that may arise, and make sure this program is ready for use within a week."

To be honest, Kaede Sensei wanted to ask about Hide's school. Has he got permission to leave the class?

However, when she remembered there were more than eight thousand names that had to be inputted while Kitaro Music School only had two administrative staff, Kaede Sensei immediately hardened her heart.

"According to Sensei's request, data input will start from 92 students who are still actively studying, followed by 430 students who only take music lessons in the afternoon, then continue with graduates who still often come here to take short courses."

Kaede Sensei gave a small nod before saying softly, "Yes, but for now we'll have lunch first."

---

The Kitaro Music School did not differentiate the place or the lunch menu between the teacher and students, only the table was distinguished. Teacher dining tables were located at both ends and at the center of the dining room.

When Hide entered the dining room with Kaede Sensei, Aizawa was already there. She had even started enjoying her lunch while chatting with girls her age. Judging from the way they chatted and laughed, it seemed like the two of them were quite on the same page, and would likely become friends. Seeing this, Hide breathed a sigh of relief.

Initially, he was worried about how to help Aizawa so that she could integrate herself with her new school. At a minimum, Hide hoped that he could be at Kitaro Music School during Aizawa's first days.

He considered various methods, but none of them could be considered a natural way.

Hide would not use his father's method by waiting for him outside the classroom, because that method made the whole class ridicule him. Although the method used by his father was now a sweet memory for him, it could not be denied that this method had made his heart languish at that time, and Hide did not want Aizawa to experience the same thing.

Fortunately, Kaede Sensei gave him a way, so without hesitation he maximized the opportunity. The problem with his absence from school, he would deal with it later.

When Aizawa saw Hide sitting not far from her table, she immediately smiled cheerfully. Aizawa already knew that his brother was helping the administrative staff at Kitaro. So she was not surprised when she saw Hide.

'What a sweet child.'

Hide smiled back, while in his mind he remembered that when he was in elementary school he would pretend not to know his father whenever he came to school.

'The first biggest problem was solved halfway.'

Slowly but surely relief filled Hide's heart. He then cheerfully introduced himself to the Teaching Staff who sat at the same table with him. Of course, from time to time Hide would steal glances at Aizawa, who was laughing with her new friend.
