Yu-Gi-Oh!: The Blue-Eyes Maiden

After transmigrating, a man seems to have been reborn as Kisara, only to be adopted as Seto Kaiba's daughter. Kisara: "So a daughter is her father's lover from a previous life? Then here's the question: (digging...) Is Kaiba a ghost...?" System spirit Kotori: "Probably not. In this life, he's a sister-complex." Kisara: "..."

P.S. The book was originally titled My Dad Is the President of AB, but I changed it because many people didn't know what it was a fanfiction of. Group number: 544869479. The group avatar is the cover. When you join, just say you're a reader.

P.P.S. The first half of the main story includes both OCG and anime card effects, which are usually labeled. They stop appearing later.

P.P.P.S. The main story starts with GX and later includes 5Ds, along with some card stories and DT. The side story starts with 5Ds, but its plot is completely unrelated, and later includes ZEXAL and ARC-V. The main story contains a lot of original-series plot, while the side story is mostly original and gets off to a somewhat slow start.
