Description
Jürgen Borisovich Volk serves as captain of the German U-17 World Cup team and is a professional tennis player. Aged 17, he stands 184 cm tall, weighs 75 kg, and possesses pale skin with a bald head.

Volk first appeared during a practice session with Kunimitsu Tezuka in Germany. He maintains a disciplined coaching approach, advising Tezuka to gain experience against top players before turning pro and recommending he represent Germany in the U-17 World Cup. During their practice match, Volk defeated Tezuka despite Tezuka activating the "Pinnacle of Perfection" technique.

Nicknamed the "Philosopher of Victory," Volk takes an analytical approach to tennis. Taciturn and disciplined, he critically assesses flaws in technique or concentration during matches. He emphasizes strong fundamentals, especially stamina and leg strength, demonstrated by daily jogging routines exceeding a full marathon. Volk rarely employs special techniques, believing overreliance weakens players. His notable technique is "Wirbel Taufe" (Whirlpool Baptism), a powerful vortex-spin serve nearly impossible to return.

In the Pre-World Cup exhibition match, Volk partnered with A. Frankensteiner against Japan's Tokugawa Kazuya and Yukimura Seiichi. After losing the first game, he analyzed and countered Tokugawa's "Black Hole" and Yukimura's "Yips" techniques, leading Germany to win five consecutive games. He secured the match victory using "Wirbel Taufe" in the final game.

During the U-17 World Cup semifinals, Volk faced Japan's Hoo Byodoin in the decisive singles match, resulting in his first professional loss after winning the first set (6-4, 6-7, 6-7).

Volk's family includes his father, mother, an older sister, and younger brother Bertie Borisovich Volk, also on the German U-17 team. His personal habits include washing his neck-warmer, a gift from a fan, daily. His favorite phrase is: "Fanaticism is always necessary, those who are fanatic will conquer. Victory can't be won by strength of skill or competent weapons, but by love." He prefers the color black, Münchner Weißwurst, and the book "Foundations of the science of knowledge."
