His name is Sakuranbou, but he insists on being called Cherry.
Cherry is a highly obnoxious and creepy buddhist monk. A
travelling priest who has a habit of popping up out of nowhere
when you least expect it, often scaring the living daylights out anyone unfortunate
enough to warrant his attention.
Just about all of the characters of Urusei Yatsura loathe him
and dread his presence. Cherry is always passing judgment on people and predicting doom.
He sees bad omens in just about everything. Usually his ill-fated
predictions come true, even if he himself has to give fate a helping
hand. Of course everyone hates his stupid jokes.
But no one dislikes Cherry as much as Ataru Moroboshi. For
reasons known only to the annoying monk himself, Cherry
constantly interferes in Ataru's life and gives him grief
for his corrupt personality, base desires and bad luck. He has
taken a vested interest in seeing through his downfall.
When Cherry is not travelling, he lives in a vacant lot, residing
in his makeshift tent. Cherry, a hopeless moocher is always trying
to turn a bad situation into an opportunity for a free meal. Eating
and being a jerk seem to be his reasons for living.
He is highly arrogant. He carries himself with an air of snobbery
that comes from being a priest. Despite his arrogance, Cherry is in fact a
highly qualified monk. He has an in-depth knowledge of the
supernatural and knows of many mysterious arts. He is good at
finding evil spirits (hence his fixation with Ataru) and
exorcising them. His exorcisms don't always work as
intended though.
