Eiichiro Maruo enters high school as a model student nicknamed Ei-chan, renowned for meticulous lecture notes and an obsessive dedication to academic order. Seeking exercise to balance sedentary study habits, he attends a free trial session at the Southern Tennis Club (STC). Lacking physical conditioning, raw speed, and athletic instincts, Eiichiro is thoroughly overwhelmed on the court. However, his exceptional dynamic kinetic vision and habit of precise data logging catch the attention of STC coach Ryuuhei Aoi and spirited aspiring professional player Natsu Takasaki.

Rather than relying on supernatural power-ups or sudden physical awakenings, Eiichiro approaches tennis as a complex algorithmic system. He catalogs racket angles, spin rotations, wind conditions, and opponent behavioral habits directly into detailed notebooks during mid-match breaks. When he clashes with hard-hitting prodigy Takuma Egawa and methodical regional rivals, his intellectual framework converts chaotic rallies into controlled tactical sequences. As competition intensifies across Kanagawa Junior tournaments and national circuits, Eiichiro must build real physical stamina to back his calculations, facing the harsh realities of aspiring to turn pro in a sport with zero margin for error.

What to Expect

Pacing remains measured, grounded, and intensely focused on technical realism throughout all 455 canonical chapters. Matches prioritize tactical shot placement, stamina conservation, and psychological pressure over exaggerated action shounen tropes.

Readers tracking the anime adaptation by Studio Pierrot will find that Season 2 concludes at Chapter 181; starting at Chapter 182 continues the storyline into national-level competition.
