Isa Yoshinori

Isa Yoshinori (伊佐 嘉矩) is a decathlete who is a former member of the Black Tigers.

He made his debut in SASUKE 36 as a promising contender under the coaching of Yamada Katsumi. Unfortunately, he lost his footing at the second half of the Rolling Hill, and fell into the water just before he was about to make the platform.

He returned for SASUKE 37, in hopes of avenging himself from last time. Unlike last year, he had a much faster pace on the Quad Steps and Rolling Hill, and although he had about ten seconds left for the Soritatsu Kabe, he made it in one go, clearing the first stage for the first time with 6.59 seconds left. In stage two, he was slow throughout, but because the added Rolling Maruta at the beginning wasn't used due to rainy conditions, he managed to beat the stage with 6.82 seconds remaining. He is now the third Black Tiger to make stage three, after his buddy Yamamoto Yoshiyuki became the second to clear just before him. In stage three, he failed the Cliffhanger Dimension after missing the first ledge.

In SASUKE 38, Isa was digested, but managed to easily clear the First Stage with no problems. His Second Stage run was also digested, but he cleared with a close 0.44 seconds left. In the Third Stage however he ended up failing on the Flying Bar when the bar landed too far to the left, causing the right side of the bar to become dislodged from the cradle, dropping him into the water.

Before SASUKE 39, in a promotional video released on October 15, 2021. Isa announced that he had left the Black Tigers and decided to compete as an independent competitor, to which he submitted an application released on the official website. Later, based on the promotional video released on November 23, 2021, he officially became a part of Akko Gundan by being a coach to train the new members. He proceeded to compete in SASUKE 39, putting in another impressive performance, making it to the Third Stage once again, and surpassing his previous year's run. He would not however reach the Cliffhanger Dimension for a second time, instead being eliminated via a Disqualification on the new Swing Edge, for illegally grabbing part of the second frame.
