Yuzuru Sawamura, born November 11th, is the older twin brother of Chizuru Sawamura. He mirrors Chizuru's fair skin, violet eyes, and similar build but distinguishes himself with sharper eyes and dark purple hair styled opposite to his brother's.

Yuzuru maintains a generally serious demeanor yet reveals a playful, flirtatious side around favored individuals like Kanade Amamiya, frequently touching or approaching her. He exhibits a mischievous streak, often pranking Chizuru by spiking his food or drinks with spicy ingredients such as hot pepper.

As an idol in the unit In-Show-Ha under D-Four Production, Yuzuru debuted before Chizuru and holds a more established career. The twins' relationship is complex: inseparable in childhood, they grew estranged after Chizuru allowed Yuzuru to take his place in a D-Four Productions audition. This act sparked resentment, leading Yuzuru to ignore Chizuru until Kanade's intervention prompted reconciliation. Though still comparatively distant and reserved toward his brother, their interactions now include teasing and pranks.

Yuzuru shows an unexplained but persistent fondness for Kanade within DearDream. His preference for intense flavors extends to a favorite food: spicy pudding.
