Academically, Yoshida excels in technology and science due to his mechanical interests, achieving science grades as high as 32nd in the class. He struggles significantly with English, placing near the bottom in that subject. His composite exam scores range from 265 to 347 points across terms.

In assassination training, Yoshida specializes in close combat, leveraging his physical strength for high-speed tackles and human bullet-like maneuvers. Karasuma rates his execution and technical skills (traps, weapons) at 5 out of 6, noting exceptional situational awareness like detecting threats from behind. His planning and leadership skills are rated lower at 2. He often operates independently but collaborates effectively in shocktrooper teams, absorbing damage for tactical advantages.

Yoshida maintains close bonds with the Terasaka Group, having met Terasaka in his first year and Muramatsu in his second year of middle school. Their teamwork is inseparable, with Yoshida and Muramatsu frequently undertaking high-risk, high-courage operations. Outside this group, he collaborates with Itona Horibe in Class E's technology squad, combining his structural expertise with Itona's circuitry skills. He respects Mimura's fearlessness and recruits Sugaya for custom vehicle paintwork. He shares a childhood friendship with Sumire Hara.

Yoshida has a one-sided crush on Yukiko Kanzaki, seated beside him, softening his expression when interacting with her. Hazama Kirara observes this dynamic with amusement. Nakamura Rio displays interest in motorcycles, leading Yoshida to feel embarrassment when she requests rides, partly due to the implication of close physical proximity.

For his future, Yoshida plans to inherit his family's motorcycle shop and revolutionize motorcycle culture through custom innovations. He and Muramatsu discuss opening a ramen shop integrated with bike displays.
