G27 with a Problematic Worldview

Born in chaos, he is the core that sustains countless worlds. Like a phoenix reborn from the ashes, he is reborn within the body of Sawada Tsunayoshi, the tenth-generation boss of the Vongola family. He had no choice. All he remembers is that his name is [Yan]. In his mind, he is Sawada Tsunayoshi, yet he is not Sawada Tsunayoshi. The space he inhabits collapses, and the god of the Katekyo Hitman Reborn world casts him into a chaotic flow of time and space. With the Vongola Rings as his golden finger, boundless spiritual power, pureblood ancestry, and an inexhaustible supply of mental energy, he transmigrates between worlds, constantly searching for new energy, hoping to recover the memories he lost before being reborn. All so he can resurrect the person he is devoted to. At last, their fingers interlock, and only then does he suddenly realize that at some point he fell into the abyss called Giotto, with no way to escape. [Our time is engraved upon the rings. At long last, I've waited for you.] Things you need to know before reading: This story is mainly set in the Katekyo Hitman Reborn world. The pairing is the protagonist x Giotto. One-on-one pairing, happy ending, slight self-insert wish fulfillment, an extremely overpowered golden finger. So much wish fulfillment! The author's IQ is below zero. If you spot any mistakes, leave a brutally snarky comment! [Cough] The entire plot is made up by this story [go away]. If anything happens to coincide with reality, then I guess it's a coincidence! A tsundere, somewhat expressionless uke X a gentle, scheming seme. The story goes from Katekyo Hitman Reborn to Bleach to Naruto and then into a chaotic flow of time and space. It features characters from several anime, including Katekyo Hitman Reborn, Naruto, Bleach, Vampire Knight, K, and D.Gray-man. Theme:
