But on top of the funny filler episodes in Kannagi, there is some thoughtful stuff between the gut-busting punch lines. It's not just about Sony.

More seriously, Kannagi subtly touches on some interesting tidbits about otaku in Japan. While we can't take what happens in the show too seriously, we see some demonstrations of what may happen when you have a relatively normal group of high school teenagers mixed with some of the more exotic elements--like some of the people who'd read this blog post.

What makes the side characters connect with fans? They are all creepy in their own ways, but it's so funny when mixed together with the rest of the cast. From Shino's knowing smiles to Akiba's fanboy diatribe, these guys have the major embarrassing fanboy/fangirl behavior categories covered.

Let's take a look.

Takako Kimura -- the leader of the group. While she may just be a senior in the art club, her personality is one that acts out and gets what she wants. However, her uniquely otaku-ish vision of their rag-tag band of artist-types blurs fancy with down-to-earth, everyday reactions. She's got the fujoshi/yaoi fangirl thing down, but she's quite tasteful about it. Despite being able to do anime OP dances to near perfection, she still couldn't pass off as an anime character in the eyes of her peers (not like anyone could). The result is an uncanny creepiness when she tries too hard.

Shino Oukouchi -- the mysterious backbone of the group. She doesn't do much, besides to keep Takako on a leash. The only other senior in the art club, Shino keeps her eyes nearly closed most of the time, or is she just slant-eyed? I can't tell. What we do know is she has something hidden up her sleeves, and I am not going to stick around to find out. The quiet, aloof, manipulate-behind-the-scene type, she is probably the biggest geek in the group that no one knows. The ninja fangirl.

Meguru Akiba -- the resident otaku. He stands as the show's main reference to otaku culture, and is even named appropriately so: Akiba is short for Akihabara, a pun for the tribal masses that shop and mingle there. Contrary to Takako's more outlandish reaction and desires, Akiba takes the straight road in regards to human relationships and he takes things seriously. As a result he gets teased by Takako a lot. As he should -- he uttered those famous words: "it's a Sony"! It's a sure sign of your typical, intelligent geek who knows too much that it can be embarrassing to try to explain himself.

Daitetsu Hibiki -- the stereotypical, introverted artist. Uncharacteristically, Daitetsu is a hulk in physique; but somehow he is as talented as he is big. His scruffy exterior reflects a degree of inner purity but it also goes against his timid personality. Awkward is his middle name and this huggable big dork is a walking sit-com plot device. Thankfully, Daitetsu's poor social skills come off as charming rather than rude.

With only a handful of episodes left in the series, the filler episodes will likely come to an end and the supporting cast will return to their respective backgrounds. But these Kannagi characters have definitely left their mark.
