Sera

Sera is gentle, perceptive and willing to question the decisions of people she loves. She shares Aigami's desire for a better existence but does not allow that dream to justify every action he takes.

Her compassion extends to Yugi even though his connection to the Pharaoh complicates the Plana's plans. Sera believes that individuals should be allowed to make meaningful choices about their own futures rather than simply having those choices imposed upon them.

She is nevertheless capable of acting independently and covertly. Her activities as Prana demonstrate confidence, intelligence and a willingness to investigate powerful figures such as Kaiba without revealing everything about herself.

Sera possesses the powers of the Plana, allowing her to manipulate dimensional space, teleport herself and others, and enter the higher-dimensional realm inhabited by her group.

She can use these abilities defensively, including moving people out of immediate danger. Her connection to the Plana also allows her to appear and disappear in ways impossible for ordinary humans.

As Prana in Transcend Game, Sera demonstrates considerable Dueling ability within the Neurons virtual environment. She uses an archetype associated with the Constellar monsters and successfully operates inside KaibaCorp's advanced virtual network.

Sera's childhood is shared with Aigami, Mani and other orphans who are rescued by Shadi. Under his guidance, they become the Plana and learn about the Millennium Items and the possibility of transcending into another dimension.

In Transcend Game, she enters Kaiba's experimental Neurons system as Prana and investigates his activities. Her actions establish her involvement with KaibaCorp before the principal events of The Dark Side of Dimensions.

During the film, Sera intervenes in the struggle over the Millennium Puzzle. She secretly gives Yugi one of its pieces despite Aigami's plans and later asks Yugi to save her brother. When Aigami becomes corrupted by the Millennium Ring, Sera continues trying to reach him rather than abandoning him.

Aigami is Sera's older brother and one of the people she cares about most. Although Sera disagrees with Aigami's increasingly extreme actions, she continues trying to protect him and steer him away from revenge.

Shadi Shin rescues Sera and the other children from abuse and becomes their mentor. His teachings shape Sera's understanding of the Plana and the Millennium Items.

Mani grows up alongside Sera and Aigami as another member of their close-knit group.

Yugi Mutou earns Sera's trust despite the danger that the Pharaoh's potential return represents to the Plana's plans. [She gives Yugi Mutou a piece of the Millennium Puzzle and asks him to save her brother.](#spoiler)

Seto Kaiba encounters Sera through her Prana identity during the testing of Neurons, and she remains interested in the purpose behind his technology.
