Sawatari Otsu

Japanese name:	沢渡 乙
Nickname:	Ossan

Otsu Sawatari is another zombie, who uses his real job as a medical graduate student to investigate autopsies and other zombie-related cases. Often mistaken for a Yakuza from his crew cut, sunglasses, smart casual dress, and demeanor, he is actually one of the brightest in his class.
He is shown fighting using ectoplasmic flames that surround his hands.
Chika often calls him "Ossan" (old man), but claims he said "Otsu-san" out of respect. Otsu's age is 24.
