Days Wikia

Jirou Haibara (灰原 二郎 Haibara Jirō) is a third year and right back for Seiseki High School who plays with jersey n°2.


Haibara has brown hair, brown eyes and he is shorter than most of the soccer team.


Sine Haibara has a small body, he lacks self confidence, unlike Hisahito Mizuki and Yuuta Usui, where only became a regular when the previous upper classmen retired. Even though he is an important part of Seiseki's strong position, he is still unconfident.


Haibara was born in Yamanashi Prefecture.


IN Episode 15, Haibara was put as the only upperclassman against a team of freshmen with Tsukushi Tsukamoto being moved to centre back.


As a short player, Haibara relies on his brains to survive. He reviews each game tape three times to analyze the game. He also has found a skillset unique to him and he hoped Tsukushi Tsukamoto can find one for himself.

Also, when Tsukamoto was put in as a centre back, Haibara made him realize the importance of defense and a defender's mindset, which would serve him well as a forward.


Despite making many runs down the right flank, he is the only person who can survive the full 120 minutes (including extra time).


Hisahito Mizuki

Haibara and Mizuki have a close relationship. Haibara can be seen scolding Mizuki for catching him practicing his kicking with Tsukushi, even beginning to climb the fence of the field to stop him. When Mizuki scores a goal during the Saku High game, Haibara hugs him, jumping onto him, and wrapping his legs around his waist.

Susumu Inohara

Haibara and Inohara have a close relationship. As right back and goalie, respectively, the two typically work together in games and can be seen together outside of club activities. After losing to Saku, Inohara places a comforting hand on Haibara's head as he sobs.
