Kyou no Go no Ni

Kyou No Go No Ni (or Kyō no Go no Ni) is the debut Japanese Seinen Manga series created by Koharu Sakuraba, originally serialized in Kodansha's Bessatsu Young Magazine from 2002 to 2003. The twenty-two chapters were later collected together in a single bound volume along with two extra chapters and published on November 11, 2003 by Kodansha.

The Manga would later be adapted into a five episode OVA running from March 24, 2006 - March 21, 2007. Even later, a full TV Anime adaptation would be developed (unrelated to the OVAs) consisting of 13 episodes between October 5, 2008 - December 28, 2008.

The story of the Manga and adaptations follow the lives of Ryōta Satō and Chika Koizumi, both now in their fifth grade of elementary school in class 5-2 together with their group of friends. The stories cover their many misadventures and complications as they go about surviving in the fifth grade and avoiding the problems that plague them at every turn.

Kodansha has announced that Xebec will be adapting an OVA version of the Anime in 2009, directed by Tsuyoshi Nagasawa, featuring the same cast as the Anime.

The series provides examples of:

 * Accidental Pervert: Ryota, oh so much.
 * Adaptation Dye Job: Koji and Tsubasa, both having black and blonde hair respectively in the TV series, seem to have switched hair colours for the OVA.
 * Air Guitar: A variation using broomsticks, one episode revolves around the boys in class doing this during cleaning duty. Completely played out like an actual concert.
 * Art Shift: In the same vein as Minami-ke.
 * Belligerent Sexual Tension: Ryota and Chika. Lampshaded by everyone.
 * Bokukko: Natsumi, the resident Tomboy.
 * Brick Joke: On the very first episode, Aihara uses Ryota's finger to pull out her loose tooth and asks him to help again when her other teeth loosens. Happens again on the final episode, much to Ryota's chagrin. Doubles as Book Ends.
 * Yet another one with an episode revolving around girl's collarbones, particularly Yuki's. Aihara later talks about it in a later episode preview.
 * Chivalrous Pervert: Koji
 * Christmas Episode
 * Covert Pervert: Aihara, of all people
 * Cross-Dressing Voices
 * Cute Shotaro Boy: The boys, of course
 * Determinator: Ryota
 * Emotionless Girl: Aihara Kazumi
 * Fall of the House of Cards: Koji finishes one when Aihara walks in and topples it over.
 * Fan Service: The OVA is guilty of this. The anime series removed most of it but still has its moments.
 * Festival Episode
 * Girlish Pigtails: Chika sports them at times, as does Kazumi in one episode.
 * Groin Attack: Yuki accidentally delivers Ryota one when she stepped on his and Koji's superballs.
 * Heavy Sleeper: Ryota
 * Huge Schoolgirl: Megumi, somewhat - she's more developed than the other girls and often worries about her weight.
 * Idiot Hero: Ryota of course.
 * It Was with You All Along: Ryota lampshades this, telling Megumi she's already wearing her glasses.
 * Just Friends / She Is Not My Girlfriend: Interestingly, Ryota only says it exactly once about him and Chika. After that, they have a lot of moments of Belligerent Sexual Tension and Aw, Look -- They Really Do Love Each Other.
 * Keet: Tsubasa. A mild case.
 * Lethal Chef: No Yuki, chalk is not edible.
 * Locked in a Room: One episode has Ryota and Natsumi both locked in a storage room together. Hilarity Ensues.
 * Meganekko: Megumi, who's also Blind Without'Em.
 * Mundane Made Awesome: Includes checking each other's heights and drawing the lottery among many things.
 * Nonchalant Dodge: Both Aihara and Koji do this on separate occasions.
 * One of the Boys: Natsumi, often playing sports and wearing boys' clothes, as well as not having any qualms about undressing in front of the whole class.
 * Pettanko: Yuki
 * Pinky Swear: Between Ryota and Chika, . Leads to a One Dialogue, Two Conversations thing later on.
 * Rock-Paper-Scissors: Whenever it appears, Ryota always loses. A whole episode also revolves around it.
 * Serious Business: Ryota treats most everything as this, particularly when his masculinity is threatened.
 * She Cleans Up Nicely: Natsumi is forced on a kimono by her family for the summer festival. Even more surprising is the fact that she finally wears a skirt by the end of the series.
 * Slice of Life
 * Smug Smiler: Aihara, during her mischievous occasions
 * Sprouting Ears: Aihara again, complete with a tail
 * Thirteen Episode Anime
 * Tsundere: Chika is Type B.
 * Tsundere: Chika is Type B.
