Oh, Japan. My avatar is from Moyashimon, or Tales of Agriculture, one of the oddest anime I've seen in my time. The storyline? A mostly normal heir to a yeast-breeding company(yeast, for what else? Sake!) has one large quirk. He can see bacteria, not on their molecular level, but as 2-inch freaking bobbleheads. This includes the yeast his father's company makes for fermenting different grains. The little guy you see there is that beast, aspergillus oryzae. He can almost always be seen trying to cheer up the main character, but his often unexpected appearances usually only cause poor Tadayasu to panic or become annoyed at his ability.
Now, that's when Moyashimon was an almost educational anime, and that was it's charm. However, that theme pretty much died at episode six. If you're really into heavily implied lesbian pairings at an agricultural university in Japan, then Moyashimon after episode six is probably your anime to watch.
