There is no grand plot going on. In every episode Tskune and his friends have to defeat another foe and they need to work out their love triangle. The focus clearly is on the latter as the fights aren't that spectacular, though the visuals are often gorgeous.
His friends (or rather his harem) are typical naive but lovable anime girls. Only Moka (due to her importance to Tskune) has more of a personality. Tskune himself is a bit lacking as he is very weak and consequently has to be rescued by his female friends all the time; a fact that he is painfully aware of himself. He would have been way cooler if he had at least one useful skill like sword fighting; just anything instead of whining about how weak he is. His weakness is also very much at odds with his protective nature.
Though plot and characters aren't anything spectacular, there are some really beautiful and funny moments to be found, lessons about love and friendship (though nothing too deep). And 13 episodes are a good match for this format.
