Finally died out of old age and was full of regrets, but now a new life was given to him and started to explore the multiverse and what will it offer to him
A few days have passed, and Miyuki is getting increasingly suspicious because the emotions of her brother are coming back is happy about it, but at the same time, she is worried that the Yotsuba clan would find out that her brother's emotions have come back.
Her brother was also becoming more awkward toward her, and it did not take her long to notice that her brother had been more conscious of what she felt toward him.
Miyuki could not stand the current relationship that she had with her brother, so she decided to confront him this weekend.
...
Ever since Tatsuya got his memories of his past life, he has been confused, he doesn't know what to do, is he Arthur or Tatsuya? or is he a new being that has the memories of both Tatsuya and Arthur, these past few days have been hard for him, as he could not sleep and has just always been thinking about what he will do.
However, his experience in school is not that bad; it has been more fun and more meaningful to him as he can express more rather than being cold and emotionless as usual; he also found that he does not have the blood of the Yotsuba clan flowing through his veins, which seems to have been found by Yotsuba Genzou as an infant during his mission.
Yotsuba Genzou seems to find out that the abandoned infant he found is a magician and also has huge potential so he adopted him and put him disguised as his daughter's son and his grand-daughters older brother as they only have the same age but different birth months.
Tatsuya has also become a subject in an Artificial Magician Experiment because the nature of Tatsuya's magic is only for 'destroying' and 'restoring' information, not 'altering' / 'manipulating' them.
Tatsuya's Magic Calculation Area is dominated by his powerful innate abilities, such as Decomposition, Regrowth, and Elemental Sight. It is because of this imbalance that he is unable to use any other form of magic. So, to enable him to be able to use other magic spells, especially the Systematic-Type Magic, his disguise mother, Shiba Miya, and her younger-twin sister, Yotsuba Maya, performed the Artificial Magician Experiment on the 6-year-old Tatsuya. Miya used her unique and forbidden Outer-Systematic Magic Mental Design Interference, forcibly altering the consciousness responsible for strong emotions (called the Limbic System) and installing a Magic Calculation Model in an attempt to create an Artificial Magic Calculation Area.
Even with this exchange for the installation of another Magic Calculation Area which granted him the ability to utilize normal magic (albeit at a significantly lower speed and power), it was still insufficient for him to be regarded as a 'true magician' by the Yotsuba.
Yotsuba Genzou won't allow this experimentation to happen if he was still alive, sadly he passed away when Tatsuya was still 2 years old because he was led on and ambushed by the remnant of the Dahan incident.
Genzou was a man who valued his family and clan immensely, going as far as wiping out approximately 4000 individuals in Dahan in the name of revenge for kidnapping his daughter, Maya (leading to Dahan's collapse). He has been shown to hold some guilt when his clan members were killed during their operations in Dahan, despite all of them being volunteers.
Tatsuya also discovered the fate of his aunt, and it seems that Maya was raped and experimented with by her kidnappers from Dahan's infamous Kunlunfang Institute. After she recovered, Maya's elder sister, Yotsuba Miya, Miyuki's mother, and his disguised mother turned all of her experiences into information, separating emotions from memories to prevent the experience from overwhelming her sister's battered psyche. As a result, she claimed that Miya killed her, as experiences made up a person and their personality.
This leads to Miyuki's gaze, and it seems she realizes that I have been distant from her lately, who is he kidding, they have been together since they are 11 years old.
However, it seems that Miyuki does not have any plans to confront him during weekdays, Tatsuya seems to also want to talk to Miyuki regarding his new "attitude" and wants to discuss something with her.
...
After both siblings eat their dinner together and do their chores, they currently sit together on the sofa with a gap in the middle silently.
The sofa is quite large, and both of them sit at both ends.
There is an awkward silence between them, and it seems this will continue for a long time if neither of them is willing to speak soon, so Tatsuya decided to be a gentleman and decided to open a topic.
"Miyuki? Is there something you like to talk about?" Tatsuya said he did not look at his sister.
"Hm. I'll be blunt Onii-sama, did you get back your emotion back?" She said Fidgeting while looking at her brother's reactions.
Tatsuya ran his hand through this hair and sighed.
"looks like it's useless to hide it more yes? And yes I recovered back my emotions" 'Well not just emotions but also my sealed memories and also my previous life memories'
"what if they would know that you got back your emotions Onii-sama, they will bring you back to that hell hole again!" She said that she stood up while looking at me.
"that won't happen," Tatsuya said while smiling before a bunch of dust psion enveloping changing his face when he still hadn't gotten his memories back.
"T- This is. Onii-sama you can manipulate Psion without removing your limiter!" She said while she hides her mouth in shock.
"Miyuki, I know this seems a crazy topic but what do you know about reincarnation?" Tatsuya looked at her with a serious expression.
