A professional hentai (pervert).
Commonly wears glasses, has a camera, sneaks around appearing from
weird places, and finally is an expert stalker. Women
will fear him,
men will either beat him up or look up to his pro skillz.
Yasudas also suffer from anemia and weakness, mainly because of excessive loss of blood from nosebleeds. The cause of the nosebleeding is uncertain, but most often occurs around cute/beautiful women.
There is no known counter-measure to his sneaky ways. Nor is there anywhere to hide. Run... run while you still can...
