With their highly volatile emotions gradually cooling as the tense moment had long passed, Aiko separated from her son to let him better heal her. Wiping the tears from her eye she asked, "Zushi, this healing light… Is it your quirk?" She couldn't be faulted for asking as it was the first time Zushi had showed the ability to another person.
"Oh, this? It a derivative ability of my Quirk..." Biting his tongue, Takezushi entered another internal conflict as the now dominant child soul within him wanted to share more about his quirk with his mom while the remnant influence of the transmigration was adamant about keeping the information of his abilities secret. In the end, transmigrator lost out again, for a multitude of reasons. The primary one being, it had been recently overpowered by the child soul after it underwent rapid growth from releasing such intense emotions. The other main reason being that it had grown attached to Aiko after being showered with her motherly love day in and day out since it had crossed into Takezushi's body.
Thus, after taking a deep breath, Takezushi looked at his mother in the eyes before he explained, "I never really went over the knowledge that had appeared in my head after my quirk manifested, did I?" Seeing her shake her head in denial, Takezushi continued, "Well, to simplify my Quirk, it transformed my body to develop a chakra network. With that network I can gather chakra from training my body and spirit and with that chakra, I can mold and transform various types of energies. The type of energy that I'm using to heal you right now is Yang energy that has been concentrated and carefully controlled so as to not damage your vitality and instead rejuvenate it."
"Oh? Then your eyes..." Aiko stopped speaking as she looked at Takezushi's eyes flicker, spin, and fade into various patterns and colors. Adding on to his explanation, Takezushi said, "The changes in my eyes are a direct consequence of infusing them with chakra. They hold some of the most devastating abilities I can summon with chakra."
As his eyes stabilized into the Mangekyo Sharingan variant that he had used against the man who had assaulted his mother, Aiko gasped as a pained expression appeared on both her and her son's face. While the vibrant pattern of the four-pointed pinwheel remained as sharp as before on Takezushi's left eye, on his right eye, however, it looked like he had gone blind. That was the backlash he received for forcefully using an ability far out of his Dojutsu range.
"Don't be sad, mom. While it looks like my eye has been destroyed, it will only be like this for a couple weeks or months." Takezushi reassured his mother before switched back to show his normal eyes; out of their Byakugan state. His current grey eyes didn't look much different from the Byakugan aside from being a tad bit darker and possessing pupils. As he came out of manifesting Mangekyo Sharingans, the apparent blindness he had in his right eye vanished. He had only lost the ability to use Kotoamatsukami in his right eye until the eye recovered.
Aiko nodded and remained silent until Takezushi fixed up the wounds all over her body. Since the extent of her injuries boiled down to bruises and cuts none of which even coming close to being fatal, it didn't take more than a couple minutes for Takezushi to see his mother once more in her original and beautiful state. As he finished healing the last of the damage she had sustained, he promptly got up and fetched his mother the other set of clothes she owned; deciding in the back of his mind to work the fields an extra bit harder tomorrow, for her to get another set of clothes to replace the ones that were ruined because of today's unfortunate events.
In an effort to heal his mother, he had to come into contact with some of the erogenous parts of her body. But because he was rather deft with his hands, possessed a disturbing amount of medical knowledge, and operated without the slightest intent of stimulating Aiko — only wishing for her health to return — not even a slightly ambiguous thought bothered either mother or son.
Aiko only realized this after Takezushi returned and tossed the clothes he had fetched to her without even looking as he moved towards the man that was lying on the other side of the wooden cabin. As Aiko quickly covered herself up, she could once more feel the temperature of the room slowly start to drop as her son approached the corpse-like body of the man that almost succeeded in violating her.
"Get up..." Takezushi spoke with evident hatred and wrath pulsing from his tone as he eyed the man like he was looking at a pile of trash. Panting as he made tons of noise stumbling to his feet, the man didn't dare let the internal injuries and broken bones Takezushi had afflicted upon him stop him from getting up, as he sincerely believed that failing to comply with Takezushi's demands would result in his immediate and certain death.

Having cultivated a sense of urgency and lacking civilization to guide him out of his instinctive bestial nature, coupled with the transmigrator's soul that understood how important it was to be ready to take a life and you had the current Takezushi. He was a young boy who showed not a hint of remorse as he commanded, "Prostrate yourself before my mother..." He had been itching to murder the man and the transmigrator's soul within him felt confident there wouldn't be any hesitation or feelings of unrest had it not attempted to sway its counterpart into putting the man under Kotoamatsukami's spell.
Not waiting for the man as he was struggling to move through the pain his body was under, Takezushi returned to his mother's side. "Zushi… this is..." Aiko started. "One of those devastating abilities I mentioned earlier..." Takezushi ended. Having garnered her attention once more, he explained, "Kotoamatsukami is the name of the technique that eye granted me and with it, anyone I target will be subject to an unbreakable illusion. They'll take in experiences I've fabricated and belive them to be reality."
Pointing at the man that was halfway through the room, Takezushi's voice took on a serious tone as he said, "I've turned him into an obedient little slave that believes me to be God." The dark and potentially destructive nature of such an ability startled Aiko, but before she could dwell on it for too long, she heard a thud.
Bang! Turning her head, she could see the man who had previously brought her to the brink of despair now, prostrating before her. His face smashed into the wooden floor as if unhappy that it couldn't be lodged any deep. There were also tears of regret, panic, and despair streaking from the man's eyes which she could empathize with.
"Mom… I really would like nothing more than to end his worthless existence right here and now. But, I've held back for you..." Takezushi said as tears once more flushed down his face. Just the thought of what would have happened had he not been so fortunate as to make a breakthrough in his Flying Thunder God Jutsu had him enter an emotional turmoil. But through the tears, he managed to speak out, "Is there anything you'd like to do to him. Any revenge you might want for all the hurt he must have put you through?"
Staring down at the ground as he was still drowning in regret for not being more cautious and proactive, Takezushi was taken aback as he felt his mother take him into her embrace. As she held him in a tight hug, he couldn't help but called out to her, "Mom?"
"Zushi..." Aiko started, holding her son even tighter before continuing, "I want you to promise me..." She was starting to become short of breath and had to stop. Helping her calm down, Takezushi activated the Yang Aura of healing which superseded the Mystic Palm Method he had already mastered through his training of Yang Release. Even as he healed her Takezushi said, "Promise you what?! I'll promise anything for you..."
"Promise me… You'll never abuse your power… Your Quirk is a very strong tool. But that is all it is; a tool." She looked at Takezushi with a seriousness never before witnessed before she continued, "I don't want to raise you to think that it's fine to abuse your power..."
Looking at his mother in total shock, Takezushi never expected her to react this way. But for her, he was willing to do just about anything and considering that her request was something so easy to follow, he didn't even have to think to respond, "Ok..." He also understood the hidden meaning from the outburst, so he turned to the man and said, "Listen, you're to continue living your life and working as you have. But don't you dare even think of ever doing something like this again, understand?" He knew she was against violence and though it pained him to let the man leave "scot-free" — the damage his throw did to him didn't even count in his eyes — Takezushi followed through with his mother's wishes and let the matter rest there.
The man looked up from his prostrating position at Takezushi as if he had been saved, before he nodded furiously and sang praises to him, hoping his actions would end the punishment. Disgusted by the man, Takezushi said, "Now get out of my house and never come back..."
With the man gone, Takezushi and Aiko spent the evening together as Takezushi was no longer in the mood to continue training at full capacity. However, even after he stopped training, his mind didn't stop thinking of the measures he would have to implement for this kind of incident to never repeat.
The next day, aside from working an extra bit harder in the field to earn the credits for Aiko to get a new set of clothes to replace the rags that were leftover from yesterday's event, Takezushi also added training Fuinjustu — or Sealing Techniques — to his training regiment, deciding to only train the Flying Thunder God Jutsu alongside his Fuinjustu until he could guarantee his mother's safety.
For a couple weeks he dedicated his life to mastering the Flying Thunder God Jutsu along with a style of Fuinjutsu called the Alert Seal, before his previous training regiment restarted. With the dedicated training of the past several weeks, he succeeded in creating an Alert Seal that Aiko could carry with her which held one of his teleportation marks. All Aiko would need to do is alter the formation of the Alert Seal and Takezushi would be able to teleport to her side at a moment's notice. Since she received the seal, she kept it in one of her pockets as it was placed on a small wooden block.
