This is probably the second part! The first part had a rather tragic ending. Everyone died except for Tsunayoshi: the Guardians of the Tenth Generation of the Vongola, Sawada Koto, the holders of the Mare Rings, and the holders of the Pacifiers. They gave their lives to protect the last angel in the mafia. Koto even paid the price of having his soul cursed to protect Tsunayoshi. The revived angle answered them by temporarily sending Tsunayoshi to the era of Vongola Primo, where he could search for the lost power and resolve. There, angle and a mysterious figure will put them through difficult trials. Only by passing the tests and restoring the balance of the world can peace return.
This is a plan of redemption: to redeem the goodness of those blinded by the mafia, and to redeem the wayward demon (not D. Spade). Tsunayoshi must emerge from the shadows and regain control of his power. Together with the First Generation and the angles, he must rebuild order in the mafia and restore peace to the twenty-first century.
P.S. The characters may be out of character, so don't read if you dislike that. Their personalities reflect only my personal interpretation.
Still a very good article~waiting for updates~
After reading your article, I don't know what to say... It seems like a romance time-travel novel, where you are forced to have sex or something...= =||| Good article, but if your brain is not flexible, it will be difficult to understand. (Update)
