[Multiple heroines (Himeno, Makima, Reze, Kiga)]
The protagonist, Chuan, was born in the world of Soul Land. His golden finger lets him gain three abilities from other worlds each time he enters a new one. Later, he leaves Soul Land to uncover the truth about certain things. The Chainsaw Man world is the fifth world Chuan transmigrates to. In the previous world, One Piece, he collected Roger's soul after his death and gave him a new body before they entered the Chainsaw Man world together.
(The protagonist is invincible, but always too lazy to fight for himself. When enemies appear, he calls on Roger to unleash top-tier Observation Haki and Divine Departure across the whole battlefield. The plot progresses very slowly, with a focus on everyday life.)
(The stories of the earlier worlds will be written in the author's future books. The protagonist transmigrates in this order: Soul Land, Earth, Genshin Impact, One Piece, Chainsaw Man.)
