Mizuno worked as a storyboard artist and episode director on series like Naruto, Bleach, Yu Yu Hakusho, and Zoids Genesis.
According to reports, Mizuno passed away due to overwork, which is known as karoushi. The medical causes of karoushi are stress induced heart attacks and stroke. It was said that Mizuno decided to take a nap at the Studio Pierrot offices and passed away in his sleep.
Mizuno’s most notable works include directing the 11th opening and 24th ending for Naruto Shippuden, the 10th opening for Bleach, and storyboarding Cardcaptor Sakura Movie 2: The Sealed Card.
