In the plot of Jujutsu Kaisen, Megumi once said, "That bastard old man named his child Megumi without even checking if it was a boy or a girl."
Megumi's dissatisfaction is actually quite understandable, because the character 'Megumi' in a name is typically used for girls.
Megumi is a boy, and the cool, handsome type who could take down half of a junior high's delinquents by himself.
Anyone who learned that such a powerful and cool (and even more rebellious in junior high) person had a name typically given to a little girl would look at Megumi with a strange expression.
The strange looks from his classmates naturally made Megumi uncomfortable and even more rebellious.
However, what Megumi didn't know was that no matter if he was a boy or a girl, Toji only had one name in mind for him.
Megumi.
Meaning a blessing bestowed upon Toji by Heaven.
Before leaving the Zenin Clan, Toji didn't know what love was, because his childhood lacked it.
Toji was born without Cursed Energy, which made his life in the Jujutsu-centric Zenin Clan incredibly miserable.
Although Toji's parents came from good backgrounds, they didn't have the talent of a Jujutsu Sorcerer, so they lived poorly in the Zenin Clan.
It wasn't until Jin'ichi Zenin grew up that things got a little better for them, and later they pinned their hopes for further advancement on Toji.
Unfortunately, Toji did not inherit the Zenin Clan's Technique as they wished, and he didn't even have a trace of Cursed Energy.
In the Zenin philosophy, Toji was considered even less than an ordinary person with just a trace of Cursed Energy.
This made Toji's parents angry and disappointed.
Later, for their last shred of hope, they threw him into a pile of Cursed Spirits when Toji was six years old.
Throwing a child into a pile of man-eating Cursed Spirits.
Outside, this would be an incredibly cruel act, universally condemned.
But in the Zenin Clan, it wasn't something difficult to understand.
This also shows the twisted values of the Zenin Clan.
Toji did not Awaken a Technique as his parents hoped; when a wounded Toji crawled out of the ground, he still had no Cursed Energy.
The scar at the corner of Toji's mouth was also left during this incident.
Toji's parents completely gave up on Toji.
The Zenin Clan was not surprised by this, and simply raised Toji along with several other individuals who lacked Cursed Energy talent.
When Toji was young, before his Heavenly Restriction fully developed, he was constantly bullied by others.
As a 'three-no' individual—no children, no spouse, no Cursed Energy—who else would they bully but him?
This also planted the seed of violence deep within Toji's heart.
Later, when Toji was in his teens and his body developed, the power brought by his Heavenly Restriction became strong enough.
At this point, Toji also began to use violence to resist all injustice, just like them.
At first, two fists were no match for four hands.
But as the fighting instinct hidden within Toji's perfect body was gradually unleashed, the Heavenly Restriction was born.
This is also why Naoya later feared and respected Toji.
Initially, he was just curious to see him, but the first meeting immediately captivated him for life.
Later, Naoya tried to test Toji to determine if he was a true strong man or just a facade, and as a result, he completely fell for him, becoming a Toji fanboy.
Naoya was a self-important person who bullied the weak and feared the strong, and many in the Zenin Clan were like this.
They were self-important due to their status, yet due to their status, they dared not resist those above them.
Later, the Zenin Clan made Toji feel bored.
Everyone feared him, dreaded him; those who had once bullied Toji would now directly avoid him upon seeing him.
Few people still spoke to Toji, and Naobito Zenin was one of them.
Naobito Zenin was hailed as the most open-minded among the 26 generations of Zen'in Family Heads.
Naobito Zenin noticed Toji's situation and understood what Toji was thinking.
So when Toji fought his way out of the Zenin Clan, Naobito Zenin did not stop him.
Because it wasn't worth it.
Letting Toji leave preserved some face between himself and Toji, and also avoided too much Family loss.
This was because Toji merely injured members of the Kuguru Squad and a few remaining Bingmembers before leaving with a few convenient cursed tools.
It was also fortunate that Toji had not yet tamed Ogama at that time, otherwise there would be nothing left in the Zenin Clan's Kiko, and then Naobito Zenin would probably have fought Toji to the death.
Toji was a Heavenly Restriction that grew step by step, not like Maki , who accumulated power and then suddenly Awakened and reached the peak.
Therefore, if Naobito Zenin had fought Toji to the death with the Bing, the outcome would truly be uncertain.
Leaving the Zenin Clan, Toji experienced what love was for the first time.
Initially, it was just physical love with Erika Fushiguro.
Slowly, Erika Fushiguro's care and anticipation for new life made this big boy, Toji, realize what love was.
"Toji, what do you plan to name the child?"
Erika Fushiguro touched her growing belly and looked at Toji.
"Megumi."
"What if it's a boy?"
"Also Megumi."
Erika Fushiguro was a little surprised.
"This is a blessing bestowed upon me by Heaven."
Hearing this, Erika Fushiguro's face was filled with a happy smile.
"Zenin Megumi, what a good name."
"Not Zenin, it's Fushiguro."
"Huh?"
Erika Fushiguro's face was full of surprise.
"I hate Zenin."
So he didn't want to give that name to his child.
"I married into the Family, so it's Fushiguro."
"Mm."
Erika Fushiguro, who vaguely guessed something, agreed to Toji's decision.
Having been together for so long, she knew that Toji's past was not good; when they first met, Toji was like a stray dog, pitiful and helpless.
Unfortunately, fate did not spare Toji.
Erika Fushiguro died, but fortunately, Megumi still had someone to care for him.
Fushiguro Minako couldn't bear to see Megumi being clumsily looked after by Toji, so she took Megumi with her and cared for him alongside Fushiguro Tsumiki.
Toji loved Megumi very much, but he didn't know how to express this love, because his parents didn't love him, so he didn't know how to express his love to Megumi .
Later, before accepting the mission to assassinate the star plasma vessel, Toji met with Naobito Zenin.
In that meeting, Toji and Naobito Zenin made a deal.
If Megumi Awakened a Technique, he would sell Megumi to the Zenin Clan.
Did Toji lack that money?
No, he didn't.
This was just Toji's way of applying pressure; no one would cherish cheap linen clothes, but expensive silk garments would make people walk carefully.
Therefore, Megumi could not be simply given to the Zenin Clan.
Toji knew this, and this was the only way Toji could think of to ensure Megumi had a good life.
And this deal also included a clause.
If Gojo died or lost consciousness for some reason, the agreement with Toji would be fulfilled, and Megumi would be appointed as the Zen'in Family Head.
Yes, Toji had decided to bet everything for the future of his most beloved child even before undertaking the mission to assassinate the star plasma vessel.
In Toji's perception, the Zen'in Family Head was the most noble status in this world.
Toji wanted to give this status to his most beloved son.
Even if the one standing in his way was the pinnacle of the Jujutsu World, the legendary Six Eyes.
Naobito Zenin had no objection to this; if Megumi truly Awakened the Ten Shadows Technique, then he naturally had the qualifications to become the Zen'in Family Head, and at that time, he would simply adopt Megumi as his godson and cultivate him well.
A Zenin Bloodline, possessing the Ten Shadows Technique, and the adopted son of the former Family Head.
It would not be difficult to push Megumi to the position of Family Head.
Moreover, if Toji, the Sorcerer Killer, really had difficulty killing the Six Eyes, it would also be considered helping the Zenin Clan eliminate a major hidden danger.
Unfortunately, fate did not favor Toji.
Before Tengen's assimilation was complete, the Karma between Tengen, the Six Eyes, and the star plasma vessel would not be severed.
Just as a second star plasma vessel quickly appeared before Tengen after Amanai Riko's death, the Six Eyes, as insurance, would not disappear before Tengen completed assimilation.
Kenjaku had tried to kill the Six Eyes and the star plasma vessel five hundred years ago, but afterwards, the Six Eyes and the star plasma vessel still appeared, and Tengen once again completed assimilation with the star plasma vessel.
Facing such an overpowered and unreasonable existence, Toji could only be defeated unwillingly.
He still had one concern, and that was Megumi ; without him putting pressure on the Zenin Clan from outside, would Megumi also be bullied like he was?
With this last worry, Toji tried to entrust Megumi to the Six Eyes.
Toji was lucky, because this final, gambling-like entrustment, Toji bet correctly.
When he was reincarnated in Shinjuku, Toji committed suicide with satisfaction.
Toji was also unlucky, because Megumi was later subjected to Possession by Ryomen Sukuna, and Sukuna used his Technique to kill his own sister, after which Megumi 's life was worse than death.
