Chara 2: Tamura Hiyori (Certified Yuri Doujinshi Artist)
Chara 4: Ogiue Chika (Certified Yaoi Doujinshi Artist)
1. Contribution to Otaku Culture.
Konata: The name says it all, Legendary Girl A. Any doujinshi she buys turns into instant hits and if her room is any indicator, she buys lots of goods and merchandises as well.
Hiyori: She draws doujinshi and yuri doujinshi at that! If thats not contribution to the otaku culture then i dont know what is.
Patricia: After analyzing her character, i have come to the conclusion that her contribution to the otakudom is significant. Firstly she intends to spread otakuism in her native country(U.S.A which sadly has been hit by a huge growth in Narutards). Secondly she listens to alot of anime music which means that she should have bought quite a few character CDs and contributed to the fandom.
Ogiue: She draws Yaoi doujinshi, which caters to the Fujyoshi section of the Otaku crowd. She has also participated in the creation of male oriented Doujinshis so she has indeed done the Otakudom proud. Plus, if i am not mistaken, she has been sighted at many doujinshi events, picking up loads of yaoi doujins.
Konata: High. Cosplaying Haruhi is reason enough for that, plus she can cosplay Shana as well if she wanted to(fanboying alert!!).
Hiyori: Unknown. I personally havent seen her cosplay yet. But she is a meganekko, so the possibilities are limitless.Patricia: Very High. She cosplays as Mikuru-chan. Enough said
Ogiue: High. If recent episodes of Genshiken 2 are anything to go by, her cosplay potential is slowly being revealed by Oho.
3.Others. aka random stuff.Konata: Plays online games and is teh awesome at fighting games. I think she and Kousaka can go one on one.
Hiyori: A meganekko. Moe level +10
Patricia: Gaijin who is proficient in Japanese. Respect + 10
Ogiue: Always harassed by Ohno about cosplay. Moe level + 15
Conclusion: I cant really decide on a winner since i like them all. But if i have to pick one i think it will be Hiyori. I love meganekkos and it is a huge plus when she is an otaku as well. But thats just me.
If you have any opinions do let me hear about it.^^
Special Mention: Hiiragi Kagami.
