Tsukasa Kagura

Tsukasa Kagura is a major antagonist of Digimon World Data Squad and is brother of Yuma Kagura. He initially appeared to help DATS in the search for the missing children, including his sister. However his true agenda was to obtain the six code keys from the humans that got absorbed into the Mao-type Digimon in order to release Lucemon Chaos Mode from his seal in the Dark Area to become the ultimate tamer.

To do this he has his henchmen, DemiDevimon and Devimon kidnap the children and bring them to the Digital World, so that with their sins confusing them, allowing them to be absorbed into the Mao-type Digimon and employs Kosaburo Katsura to get the Code Keys while DATS defeated the Mao-types. But when Kosaburo failed to get the Code Key of Lust from DATS he sends Creepymon to eliminate him and his Biyomon. However after DATS defeat Leviamon, Kosaburo appears injured and reveals that Kagura was the one who was employing him all along (Kosaburo only figured this out by attaching a tracking virus to the Code Keys he sent to his "client" and this led him to Kagura), Kagura then reveals his involvement and sics DemiDevimon and Devimon on DATS but they are defeated but Kagura escapes. After Creepymon is defeated, DATS with Yuma and Kosaburo encounters Kagura as he undoes the seal and Lucemon is free. However, Lucemon refuses to be used and instead absorbs Kagura, revealing him to be the final Code Key, the Code Key of Pride. He also reveals that he was manipulating Kagura the whole time. After Lucemon is defeated, Kagura emerges from Lucemon's data and is told he must answer for his actions.
