Kanna damaged his Achilles tendon back in middle school, but even after healing from it, he still can't jump, caused by a trauma. Even so, while he couldn't jump because of his actual injury, he practised serving everyday, which is why he is now an amazing server, able to precisely control the ball's course. In his last volleyball game in middle school, he was put in as a pinch server and this ability of his almost made his team win, but in the end they failed and lost.
