Awasome. So many tags. I hope they're going to show in an anime series hahaha.
i don't see where fate/stay night comes in....
Shirou and Shinji are walking near the far right.
+Points for Kamui.

- Points for skipping the P3 Hero :<
We can use note to mark the characters.
i try to find more info..there are still missing so much..
this is too much fun for this pic
some people i don't know
but this is so good
O_o Ooh! Mutou Kazuki, Fuukin inchou, Hibari Kyouya and Rokudo Mukuro HAKKEN!
I liked fireattack's five month old idea, so I decided to start!

Any help tagging characters I don't know or don't remember everything about would be appreciated. Formatting as follows:

Name: (character's full name, surname first unless not Japanese)
Origin: (manga/anime/game/etc character is from)

Also, I thought the best way to fit the tag in was to make it like a little "my name is" badge. :P
So far I have the boys from Yu Yu Hakusho (where's Hiei? :[) and Jotaro from Jojo's Bizarre Adventure. I can/will eventually do the rest of the Jojo characters, the Yu-Gi-Oh characters, the Hikaru no Go boys, the CLAMP characters, the Urusei Yatusra characters, and a few others I recognize here and there. Right now I need to go to bed, though. u.u
is it just me or everyone of them are characters portrayed in school uniform?...
Prepare for the ultimate school ass whooping of a life time
事实证明...国中高中才是男儿热血的鼎盛期...
AAHH! they got the Uesugi bro's from Touch. and Devilman looks like he's ready to kick some a$$.
The guy with a pompadour between Rokudo and Kaiba is Josuke Higashikata (JoJo's Bizarre Adventure - Diamond is Unbreakable).
The guy between Kaiba and Jonouchi is Noriaki Kakyoin (JoJo's Bizarre Adventure - Stardust Crusaders).
The guy leaning on Shirou is Shinji Matou (Fate series).
The guy that goes after Shinji is Shiki Tohno (Tsukihime).
The guy two spaces to Tohno's right, wearing a cap, glasses, and holding a round object in his hand is Zera (Litchi Hikari Club).
Right next to him are three guys engaged in an awkward embrace: the guy stepping on someone's cape is Persona's nameless protagonist, also known as the Boy with Earring; the guy in the middle, with weird upward bangs, is Eikichi Mishina (Persona 2); the guy with bangs covering his right eye is Jun Kurosu (Persona 2). Not quite sure of Jun since I'm not all that familiar with the SMT franchise and as far as I know he doesn't wear that uniform.
The silver haired guy looking at the trio is Persona 4's protagonist, most famously known as Souji Seta, or Yuu Narukami.
The guy to Seta/Narukami's right, with cap, cape and pointy sideburns, is Raidou Kuzunoha the XIV (Devil Summoner: Raidou Kuzunoha series)
The guy next to Akira Fudou, holding a worm is Ken Ichijouji (Digimon 02); the worm is Wormmon. Behind him, the guy with a bandaid on his left cheek is Kenichi Shirahama (History's Strongest Disciple Kenichi). Kenichi is bumping arms with Kyo Kusanagi (King of Fighters).
I think the short nervous guy in front of Kazuo Kiriyama might be Ren Mihashi (Okiku Furikabutte).
Pretty sure that's NOT Araragi Koyomi since Araragi doesn't wear geta and the character in the picture has shorter hair than he does, and is also missing Araragi's characteristic ahoge.
The kid wearing what seems to be Physical Education pants in front of Watanuki Kimihiro is Tarou Komori (Ghost Hound).
The guy crouching next to Sakuragi is Takashi Mitsuhashi (Kyou Kara Ore Wa!!).
The robot to the far right is Mechazawa (Cromartie Highschool).
By chance I found out who the character tagged as Araragi is. His name is R. Ichiro Tanaka, and he's from a manga series called Kyuukyoku Choujin R.
