| Sugoroku (Before Season 0)
A sense of sorrow filled him when the box holding the puzzle was lifted by the old man – Sugoroku Mutou. The man himself was not bad by any means, in fact he respected him for his kindness and wizened mind.
When the man had first held the box when buying it from a sales clerk, something in him had been awoken. He had been overflowing with a sense of accomplishment that day – had he found the person he was searching for? Anticipation filled his heart whenever the man tried to fit the pieces together. One of these days, he'll repeat to himself anxiously, one of these days Sugoroku will surely finish it.
It was his personal downfall. He had failed to scan the man himself of his energies; had he felt the man, he would've realized sooner that the man, while far closer to anyone who's ever tried, still failed to match his. His spirits fell soon after and with it, all opportunities for the man to complete the puzzle.
It would seem Sugoroku sensed his inevitable failure. For days, the man would stare at the puzzle he laid out on his private desk. He could sense the man's frustration. Towards himself or the puzzle, he did not know for sure.
Regardless of the man's frustration, it didn't matter in the face of reality. Only when the person was completely compatible with him could they channel the knowledge he contained within himself through themselves in order to complete the Millennium Puzzle.
However, just as said, he held nothing but a respectful attitude towards the man.
That is why when the man said that he was sad to say he was giving up on completing the puzzle and putting it away in a safe place for storage, he found himself just as sad. He would miss the old man's benevolent attitude.
Nonetheless, he had to continue onwards. He needed to find that person.
