Jackal Kuwahara

He has a distinctive appearance with dark, tan skin, a result of his half-Brazilian heritage.

Jackal maintains a shaved head to honor the senior who coached him in Brazil. He keeps it as a reminder of his original passion for the game, even after returning to Japan.

Though he often appears cool and composed, Jackal is fundamentally a kind-hearted and caring individual.

He is a classic long-suffering character who often finds himself in thankless situations. His good nature means he frequently gets pushed into taking on difficult roles for the sake of his more eccentric teammates.

Jackal is of mixed Japanese and Brazilian descent and learned to play tennis in Brazil.

He returned to Japan and enrolled in Rikkaidai Junior High, bringing his exceptional physical abilities with him. To stay humble, he keeps the shaven-headed look inspired by his first coach.

His play style is that of a Counter Puncher, excelling at returning opponents' shots.

Jackal possesses extraordinary physical abilities, most notably his immense stamina. This has earned him the nickname "The Man with Four Lungs."

In doubles, he is called the "Iron-Walled Defender" for his nearly impenetrable defense that prevents opponents from scoring.

He also demonstrates surprising technical skill, capable of returning tricky shots like Kaoru Kaidō's "Boomerang Snake" with a perfect copy of the technique.

Signature Moves

Hana-Beat

This is a Repetitive Defense (Turn Defense) technique where Jackal enhances his footwork by wearing 20kg power ankles, allowing for relentless defensive coverage.

Positive Defense

A testament to his defensive style.

Jackal is a core member of the Rikkaidai tennis team and often plays the role of the responsible, if exasperated, figure among his peers.

He and his doubles partner, Bunta Marui, share a classic comedic routine where Marui will declare a bold action, ending with "...Jackal will do it!" to which Jackal always retorts, "Me?!"

He is part of the "Platinum Pair" with Bunta Marui and the "Kaishikan" group with Seiichi Yukimura, Genichiro Sanada, and Renji Yanagi.

Though their partnership is tested in *The New Prince of Tennis*, it's ultimately affirmed by Eishiro Kite that Jackal is, without a doubt, Marui's "one true partner."

The Prince of Tennis

During the Kanto and National tournaments, Jackal partnered with Bunta Marui in doubles matches against Seigaku.

In the Kanto finals, they faced the Takeshi Momoshiro and Kaoru Kaidō pair. In the National finals, they battled against the Golden Pair (Shūichirō Ōishi and Eiji Kikumaru), where he showcased his enhanced defensive techniques.

The New Prince of Tennis

In the U-17 training camp's drop-out tie-break match, Jackal was unfortunately defeated by his own partner, Bunta Marui.

After being allowed back into the camp, he felt a sense of loneliness and shock upon hearing that Marui had been practicing with Eishiro Kite. These complex feelings grew when he saw Marui and Kite being praised as an "ideal doubles pair" during a ranking match.

However, after the finals selection matches, Eishiro Kite reassured Marui by telling him, "Your real partner is here for you," explicitly confirming within the story that Jackal is Marui's true and only partner.
