Episode six was, in a word, confusing. In three words, confusing as ****.
For starters there seemed to be a chunk missing between episodes five and six because Akira hadn't even mentioned Saki's group before episode six, yet at the start of it he was dropping Saki off at her friends and asking her to arrange a meeting. Somewhere along the way a "Hey baby, wanna come back to my place?" line was transformed into a plan to meet Saki's group of nerdy friends.
Before episode six, I think the word 'club' had only been mentioned once, and the club members had only had a few seconds on screen, so you'll have to forgive me for not getting how a 'romantic' offer changed into a plan to meet Saki's club friends. Why is she even in with nerds, anyway?
Anyway. The next scene introduced the club cast as they talked about Akira and how the geek leader wasn't so great and how the attractive ladies were all leaving the club...or something. I really don't know. All I do know is that they decided to pay Akira a visit at the end.
When they started conversing with Akira, it got REALLY confusing. Some stuff about a program that can add descriptions to any image viewed on a camera, the club being involved in recycling(!?), old men being evil, a bad thing happening to Saki because of the image description program, Akira wanting to use a group of six nerds to save the world by funding them...oh, and there was a very calm discussion at the end about the virgin nerd getting his "Johnny" chopped off. Too much was threw in and explained badly, in short. I wish I hadn't watched it at 1 AM because, if I ever watch episode 7, I'm going to need to rewatch it.
I think the message of Eden is that old people are ruining Japan and young, reclusive people can save it if they're helped. I don't really care at this point, though. Why? Because the series is all over the place - it isn't sure if it wants to be a slapstick comedy series, a Genshiken type comedy, a crime thriller or an anime that shows Japan from a certain angle. I enjoyed the rom-com opening episodes (despite not really liking either character) but have become less interested in it as its gone on. I might drop it - I'm not sure.
