The owner of a café which Sawawa frequents as she loves the parfait the café makes. A moustached, dandy looking man. In the manga, he only appeared in one frame in the background but in the anime he appeared a number of times. His parts largely has nothing to do with the main story.

He treats her to free parfaits, gives her lottery tickets, and even wanted to rename the café "Sawawa", with his gifts becoming more elaborate each time. The name of the café is unknown in the manga, but in the anime it's called "Dandy (伊達男)".  (Source: Wikipedia)

When Hiro Hiyorimi tries to save a beautiful young woman from certain death, he ends up a dead hero himself! However, since the drop-dead girl is Hime, daughter of the King of the Monsters, his "reward" is to come back as a not-quite-living soldier in her honor guard of horror! That means helping fight off the army of supernatural monstrosities Hime's siblings are unleashing against her in hopes of moving up the ladder of succession. 
And if facing off with vampires and zombies isn't bad enough, how can anyone be prepared for the REALLY weird ones, like were-sharks, pandas and killer dumplings? This sure as hell isn't the afterlife Hiro was hoping for, but the really sad part is that Hime is the good girl in all of this... or at least as close to good as you can come when you're on the wrong side of the gates of hell!
