The web novel Kikakugai Shirouto no Pro Yakyuu Jinsei (The Professional Baseball Life of an Unconventional Amateur), written by Jaja and hosted on the Kakuyomu platform, has reached Chapter 372, titled “Vicious Lineup.” The story continues to follow the trajectory of a non-traditional talent navigating the rigors of professional baseball, focusing on the high-stakes dynamics of international competition and the transition to Major League Baseball.
Japan vs. Netherlands: Saejima Takes the Mound
In the latest narrative arc of Kikakugai Shirouto no Pro Yakyuu Jinsei, the plot centers on a critical opening match between the Japanese national team and the Netherlands. According to the text in Chapter 372, the responsibility for the opening start is given to Saejima.
The stakes for Saejima are heightened by his current professional standing. The narrative establishes that Saejima is slated to play for a Major League Baseball (MLB) club starting this year. This transition to the American big leagues serves as a primary driver for the character’s development, as his performance on the international stage directly impacts his perceived value and readiness for the MLB environment.
Narrative Focus on the “Vicious Lineup”
The chapter title, “Vicious Lineup” (凶悪打線), refers to the offensive potency of the opposing side. In the context of the Japan vs. Netherlands matchup, the story explores the clash between Saejima’s pitching capabilities and a batter’s box filled with high-impact hitters.
For readers of the series, this sequence functions as a test of Saejima’s growth. The “unconventional” nature of the protagonist’s journey—moving from amateur status to the professional ranks—is highlighted here as he faces a lineup designed to dismantle elite pitching. The tension is built around whether Saejima’s unique approach to the game can withstand the disciplined and powerful hitting style characteristic of the Dutch national team’s top performers.
The Role of Kakuyomu in Modern Sports Fiction
Published on Kakuyomu, a Japanese web novel platform operated by Kadokawa, the series utilizes a serialized format that allows for deep dives into the technicalities of baseball. Unlike traditional sports manga, the prose format of Jaja’s work allows for more extensive internal monologues regarding pitching strategy, velocity, and the psychological battle between pitcher and catcher.

The series has gained a following by blending the “underdog” trope with a detailed exploration of professional baseball’s organizational structures, including the complexities of moving from the Nippon Professional Baseball (NPB) sphere toward MLB.
Contextualizing the Japan-Netherlands Rivalry
While the story is a work of fiction, the matchup between Japan and the Netherlands mirrors real-world international baseball trends. The Netherlands is frequently one of the strongest non-American/non-Asian teams in the World Baseball Classic (WBC) and other WBSC events, often fielding players with experience in the Dutch Honkbal Hoofdklasse and various professional leagues globally.
By placing Saejima in this specific matchup, the author uses a realistic sporting rivalry to ground the fictional “unconventional” elements of the protagonist’s skill set. The clash emphasizes the gap between regional dominance and the global standard required for a successful MLB career.
Readers can follow the ongoing progression of Saejima’s career and the specific outcomes of the Japan vs. Netherlands series through the official Kakuyomu publication page for Kikakugai Shirouto no Pro Yakyuu Jinsei.
