With the full recovery of his parents and a decade of restless searching, Tsukuyomi hasn't heard of anyone knowing a Great Healer as Sukuna as if his entire existence had been riddled with mist blinding even those with higher authorities.
But Tsukuyomi knows that he once existed, as the memories of the ruins, a blessed paradise that he had experienced beforehand are still freshly engraved into his mind.
A decade ago after the Great Healer left, Tsukuyomi went to ask a certain individual who might know of his whereabouts but...
One of his aides who guided Sukuna to the main Hall said.
"Pardon? I apologize Clan Head but... There's no such visitor in our abode which holds the name Sukunahikona."
Bowing his head, he apologizes to Tsukuyomi for not knowing the answer to his question.
Tsukuyomi grew confused about the situation and led hundreds of agents to find a single individual, either outside the main house, outside the walls of the Clan, and the Wilderness beyond the realm, but decades have passed and there's still no news of him being found.
Izanagi, the Father of the current Head of the Mikoto Clan is still deep in his slumber, never knowing when he'll be waking up.
Izanami sat by his side all those times as he fed and nourished his weakening body which lacked nutrients.
Before her nursing, she had also ordered one of the Clan's men to seek the help of one of the Ruling Individuals in the Underworld, to lend her a device which could awaken Izanagi.
3 years later, Tsukuyomi found a small hint about Sukuna's whereabouts and the agent whom Izanami sent to the Underworld also delivered a letter through a shinigami with great news.
This time of the year, they were both positively fortunate that in the flow of time and effort they've exerted, it finally bore fruit.
Two individuals approached two different methods to awaken Izanagi, One, is that for Izanami to awaken him through external means, and two, is for Tsukuyomi to find Sukuna to help him awaken his Father from his deep sleep and to also ask him a certain question which lingered in his mind ever since that day.
However, Izanami only approached the 1st method as she was growing anxious for unknown reasons. Although she trusted Tsukuyomi wholeheartedly and left him to his own devices years have passed and the results haven't bore any fruit.
So Izanami took the matter of awakening Izanagi into her own hands, relaying a message to his child that she'd be trying another method in case he was unsuccessful in finding the unknown healer which no one knows if he existed throughout the ancient history of Gods.
Upon successfully knowing that the device will be on its way to the Mikoto Clan, a year has passed and not a letter came from the agent she had sent in the Underworld who holds it.
Izanami led a hundred men to trace the agent's whereabouts. 2 years passed and finally they arrived at the Underworld passage which is located in an underground cave, very far from their territory.
As they were marching in the Underworld passage, she saw the agent she had sent.
Lifeless, with her core broken into dozens of pieces, five of her men immediately went in to search the corpse's body and found a tattered old wooden box with a sealing talisman placed on top of it.
The march stopped there as they all came back outside the passage with the corpse and the wooden box that Izanami was looking for.
She then left the same five men who went in for the search just outside the Underworld Passage to investigate the unforeseen death of her subordinate.
With that Izanami and the others have continued to go back into their clan.
The Goddess of Creation placed the box into a confined container with another seal on top of it, warding off anyone apart from her from opening it and gave it to her most trusted person as they marched through the endless plains, mountains, rivers, to avoid any disturbance, they kept a low profile to lower the percentage of being found out, all this while hiding their Divine Aura, all to pass an uncharted territory.
Another year later, Tsukuyomi was stuck at his desk trying to piece together the puzzle.
A year ago when he was chasing a seemingly similar Old Man according to the description he had written himself which was reported back to him by his men was certainly just a look-alike of Sukuna but was never that person at the start.
Now, Tsukuyomi is back at the very beginning of his search, with no progress of sorts, he muddled, shutting himself for the time being to study in the Family Archives, hoping to find a clue.
Peace went on in the Mikoto Clan, and with another 2 years passing by, his Mother arrived home with her subordinates. Leaving the rest to do their recently vacated jobs and the others to guard off and seal the entrance to the main house.
Tsukuyomi was made aware of his Mother's arrival through an information network that the Mikoto Family have built, solidified and a trustworthy information gathering channel with hundreds of years of history.
He was not surprised by her Mother's success in gaining the item which could awaken Izanagi but, he still didn't give up on finding Sukuna as there were so many questions he would like to ask.
He even went as far as to get a proxy to manage and maintain the Clan while both of them were away.
Now that he is temporarily freed of his responsibilities as the Young Clan Head. Tsukuyomi embarks on a road of no return, finding a certain individual's whereabouts which has been lost since decades ago.
"I swear, I'll find you and get my answer... Wait for me.
Sukuna."
