"Chibaku Tensei / Six Paths Chibaku Tensei" has a single entry, and lists "Nagato / Naruto and Sasuke, Hagoromo and Hamura" as its users. It's a kekkei genkai sealing jutsu.

Six Paths Chibaku Tensei is invoked when two users simultaneously touch their target with the "Yin" and "Yang" seals. It rips a giant chunk of earth up and turns it into a heavenly body, becoming the Prison of Six Paths (六道の獄 Rokudō no Goku) that can capture all things (万物捕, "banbutsuto"). It's a sealing jutsu that can be used by individuals who awaken Six Paths Senjutsu. "Chibaku Tensei" is the version that can be used by a single individual, while "Six Paths Chibaku Tensei" is a more powerful version that requires two individuals simultaneously combining the power of Yin and Yang. It turns the sealing target into a gravity core in the sky, which attracts chunks of earth that bury them alive. This forms a heavenly body in the sky that can act as a prison for even a tailed beast. The section in the bottom left describes how the moon was the result of Six Paths Chibaku Tensei, and that so much chakra was contained within that it turned into a gigantic sattelite. It also describes it as a giant sealing stone (封印石 "Fuinseki"), which implies that Kishimoto took some inspiration from those giant "sealing stones" you sometimes see -- the big boulders with the kanji inscribed on them, usually with the ceremonial ropes adoring them.
