Shirogane Miyuki

The Love War Veteran
Shirogane Miyuki is one of the protagonists in the Kaguya-sama wa Kokurasetai series. He is a second-year high school student at Shuchi'in Academy and the president of the 67th and 68th Student Council.

Miyuki's mother left his family when he was a child, taking his younger sister Shirogane Kei with her as she fell "out of love" with her husband. Miyuki's father's factory was shut down and currently has no stable employment. They live in an apartment that costs ￥50,000 (Approx $450) a month. Due to this hard past, he has been led to a frugal lifestyle of part-time jobs and hard work to support his family. He has a bad relationship with his sister, due to his overprotectiveness at a time Kei wants to be left to her own devices. He passed the Level 2 Kanji Kentei exam and has passed Grade Pre 1 on Eiken. He has also got second place on the National mock exam.

Miyuki transferred into Shuchi'in Academy during his first year of high school on a scholarship. His first week was a disappointment in that a great majority of his peers were condescending to him because of transferring in and being "impure". Miyuki was being recruited to serve as the new student council general affairs officer by the Previous Student Council President and helped clean up a swamp. There, he saw Shinomiya Kaguya saving a girl from drowning, despite not knowing how to swim (though she had her maid to drag her back, the planning of which he also admired). It was at that moment where he was truly charmed by Kaguya. At the advice of fellow student council member Ryuju Momo, he adopted the confident genius personality he is shown to have at the story's beginning in order to attract her.
