Tanaka Machi, known as Pony, holds the presidency of the Student Council. Her demeanor is reserved and stern, typically maintaining a cold, businesslike expression and speaking sparingly. She secured her leadership position through electoral fraud in the original world, manipulating the election results by exploiting Hoshi's connections.

Pony possesses the ability "Switch," enabling her to teleport by swapping the positions of two objects, one of which must be in her physical contact. This power offers tactical advantages, such as escaping confinement or relocating items. She demonstrated this utility by trapping Mizuho's cat, Tora, as blackmail leverage after falsely accusing Mizuho of arson.

Within the student group, she collaborates closely with Hoshi to enforce order and organization. Her leadership approach involves exploiting her authority to suppress dissent, aligning with the narrative's exploration of hierarchical power structures.

Visually, Pony has long black hair and wears the standard school uniform. Her design, contrasting with characters like Mizuho, emphasizes her rigid and controlled personality through subtle details in posture and expression. No additional narrative developments, backstory expansions, or appearances beyond the core series are documented.
