Today is July 31st, the second day after Casio had finished his door pushing ceremony. Last night, he had obtained the physical strength he desired and unexpectedly reconnected with his butler, Amos.
Although Amos didn't recognise Casio, they quickly agreed to cooperate. This was both due to their previous sparring and similarities.
Perhaps, they had different objectives. But the ways to achieve their goals were the same, and also the results.
Strong cooperation could achieve what both sides wanted in a short period of time. Casio considered this to be a good deal.
Upon returning from the Era of Retrospection, he gained power that could overturn the existing order. In a short time, he had taken control of the Black Spade "A" Organization, defeated the Sand Dust Organization, and reacquired the Devil's Book.
He even uncovered the core secret of the Organization, and reestablished cooperation with Black Mechanism. Everything was progressing in a good direction.
