You might be asking why Junichirou seems upset after getting his technology. Although it is not as awesome as Gundam, Spaceship or a teleportation device, it is still a useful technology. After all, this technology can be said to be quite cool since you can strengthen your kick using electricity.
The reason is actually that there is no notification…
As for what notification?
'AAAAAAARRRRRGGGGHHHHH!!!!!' Scream Junichirou inside his mind as information of the technology enters his brain IMMEDIATELY! He is scared that if he truly screams, Ayase will once again come into his room and he will not be able to explain what happened to him.
With the influx of information, countless knowledge, data, and memories unknown to him appear in his mind. It was a bizarre experience that will be envied by those on the eve of a big test but will be hated by those who truly experienced it.
Actually, the process only took 3 seconds before stopping but it seems like a year or more has passed for Junichirou who digested his newfound knowledge forcefully.
"Hah… Hah… Hah… That was a hell-like experience… "

'TOO LATE!!!' curse him.
After stabilizing his breathing for a minute, He starts to inspect the first technology that he gets. Although he got all the knowledge he needed to create it, it seems he still needs to learn some basic knowledge before he can fully understand the whole technology.
'Looks like from a glance that this technology works on the principle of Muscle electrotherapy.'
Normally, when humans use their muscles, they will only spend a percentage of the chemical energy stored in their muscles cells. However,...
'This shoe allows 100% conversion of chemical energy to kinetic energy in the muscles allowing the wearer to kick with greater strength!'
Through him with awe at this technology.
'I remember that this principle has already been used to a certain extent in another field… Cooking that is… it seems if you defibrillate (electric shock) a steak it will become more tender.'
This is called a tenderization process that causes all excess chemical energy stored in meat to be expended causing the meat to be more tender. All the meats you buy in the supermarket are usually already tenderized using electricity.
'Though it has never been applied for this use because of very important reasons… Safety'
First of all, how much electricity is needed and how to make it spread evenly is one problem. After all, there is no way that after using this shoe the wearer will lose some cells due to it being electrocuted and burn injury…
'Of course, the most concerning reason… Battery! This is almost unscientific! How the heck does the battery inside Conan's shoes never explode after all those kicks, steps, and bizarre activity!?!?!'
Junichirou can only be flabbergasted by this logic. Though, He seems particularly relieved and happy seeing that this technology is actually a set with shock absorption material technology. It seems that this shoe uses this new material to resist the impact and shock from the wearer wearing shoes.
Deciding to think about it later, He starts to inspect himself first.
First= Current status? He is Aragaki's son, a web writer, income? Haha...
His father is a member of the Federal Parliament of Japan and his mother is the president of PTA (an electronic company).
At the age of 17, He was a sophomore at Chiba Prefecture High School. He usually stays at home and does not attend classes. At this point, He frowned.
'I was not expelled without attending class? Don't I care about school?'
After searching the memory a bit, it turns out that he is still going for an exam. As for the reason for not attending school, while otaku degeneration is one aspect, the most important point is because of a certain incident in his final junior high school...
'Well, I really don't know what to say... Do I just need to graduate from high school and only want to be a high school graduate in Japan? Tch...This title is quite dangerous since I can't get a job anywhere…'.
His current memory is that he crossed and merged with the memory of the original owner, Junichirou. And it seems that there is still a lingering wish of the previous owner. Wish to protect his sister that is...
'Well, it doesn't really matter since I will protect Ayase-chan!'
Well, From now on, He will be Aragaki Junichirou. At this point, he feels more comfortable and feels less guilty.
Next on the list,
Second= Will the original owner affect his behavior and thinking?... Need to observe;
...
Third= The cause of this guy's death?
…
…
…
'Looks like this guy got murdered by his sister and then I came, and his lingering soul is fused with me. To think that the reason for Ayase dere dere to be this dark… Truly a yandere…'
While nodding, Junichirou thinks of what he will do in the future?
'Hehe… Naturally, everything the protagonist should do!'
'I am also the protagonist… probably.'
He then habitually propped his head with his hands, looked out the window, and couldn't help but think about Ayase, Kuroneko, Kirino, Saori, and whether there is another character from anime he knows...
'Haha, everything will be known in the future!'
Seeing that it is almost 7 pm already, Junichirou decides to stop thinking and prepares to come down for dinner.
'If I'm late, I guess that sister of mine will probably come upstairs again to scold and nag me… Haha! I'd Better not!'
Though before everything else…
'Let's see what is under the bed!'
At that moment his face turns into panic. 18+ stuff is something normal for this otaku predecessor. But if almost 80% of that is something related to a younger sister… My goodness, you have a sister!
'If Ayase saw this…'
He couldn't help but shiver.
'Shit! I need a way to throw away these things before I get sent to the German Orthopedic department!'
(it is a joke about someone who has a relationship with his little sister and is then sent to the orthopedic department in Germany after being found out by his parents…)
'Let's throw it away.'
Since He has been given this opportunity, He has to change himself and work harder. Though, he still needs the right time and place for throwing all of that.
"Junichirou, let's have dinner!"
While he was thinking about how to throw these forbidden books, He heard someone knock on the door in a daze.
The voice is quite "soft".
Junichirou quickly threw the book into the box under the bed and opened the door.
'Should I say that she is Ayase's mother? She has a similar image with Ayase.'
She has short hair with ears uncovered, but she feels intellectually gentle. Wearing a cute yellow apron, She looks good with a smile. Probably as a mother, she smiled with a warm and reassuring feeling.
'I should have called her mother right? sure enough, I still can't speak.'
I really don't know how the seniors who transmigrated can call their parents the first day they meet despite being mostly introverted.
After opening the door, Junichirou is entangled whether to call her mother. He stood still there thinking that for a while.
Then, his mother looked up and down Toward Junichirou, then said with satisfaction:
"Yeah, yeah, your face looks much better, but you still need to pay more attention to rest. Let's go and eat. Ayase has made many dishes you like."
Junichirou, who had cleared his entanglement, quickly followed his mother downstairs. Stepping down the stairs, He went to the dining room of his house.
At a glance, the dining room can be described as similar to the one shown in the anime with a kitchen beside it. The table and chairs are of western style with a higher height than the Japanese short traditional tables and chairs.
Junichirou sees that the table is already full of food for dinner with Ayase and his mother Ayaka working in the kitchen. On the other hand, his father Hitoshi is sitting on one of the chairs reading some documents, probably one of those files from his job as a senator in Japan.
Five or six dishes, rice, and a pot of soup in the middle.
The family sat down, looking at Junichirou next to Ayase. Although this kind of thing is common in a family, it always feels uncomfortable to be watched by a group of people.
Just like the teacher asks one person to answer a question, some people cannot make a sound while the whole class is watching, and some people's voice changes.
Fortunately, it didn't last long and Junichirou only felt that his movements are a little stiff.
"Itadakimasu! (let's eat!)"
This was a habit he never experienced.
While eating, Ayase's father looked at Ayase with a smile, but naturally revealed a sense of majesty and self-confidence. His eyes were firm and clear, making it easy to trust and respect.
He wears house clothes, loose and convenient. It looks like it should be easy to get along with.
Though, he is probably a daughter-con like Kirino's father.
The family talked while eating. Watching Ayase and his family eating together, He suddenly thought of something.
'Is this a family?'
It's been a long time since he lost his parents in his old world. In fact, his name Blank can be and might also not be the only thing they left behind…
'After all, can you agree that blank is a name?' Junichirou thought as he focused on his food.
