Too many anime series have been polluting the harem genre with creativity. Ichigo 100% is not one of them. This isn't a series that needs explanations, a plot, character development, or anything that might require mental effort. In fact, it's a harem so incredibly blatant that it even saves you the trouble of classifying the characters:

Failed Confessions: Abundant

Misunderstandings: At least 1 per episode

Fanservice: The series is named after a pantyshot in the opening sequence

For good measure, the series periodically throws in a new girl for no apparent reason. There are probably explanations in the manga, but it wouldn't surprise me if there aren't.

To make a long story short, you'll love this anime if you're into harems, and you'll be bored out of your mind otherwise.
