Yuusuke is a tall and handsome young man with light-colored shaggy hair, light-colored or dark-colored eyes and there are sparkles drawn around him, which implys his popularity.
Yuusuke is shown to be a prideful individual, being hurt when he finds that Fuutarou Uesugi never noticed him despite being ranked second in their grade for most of their time in high school. Also because of his pride, he desired to score higher than Fuutarou in a fair competition, throwing out the test answers his father gave him.
Yuusuke is envious of Fuutarou because he is always academically the best student in his grade, leaving Yuusuke a pitiful second place. Yuusuke considers Fuutarou his rival, much to Fuutarou's unawareness. At school, Yuusuke mostly approaches Fuutarou in the bathroom. After Fuutarou places third in the mock exam, he becomes Fuutarou's second male friend in high school. For the Kyoto trip, he is revealed to have formed a group with Fuutarou and Maeda to explore the city together.
- The surname Takeda is a reference to the Battles of Kawanakajima between Takeda Shingen and Uesugi Kenshin during the Sengoku period of Japan.
