Full Contact (also known in some circles as Furu-Kon or FL-CN) is a 6-volume Slice of Life Martial Arts/Sports Shōnen Manga written by Kabuto Kitahama with art by Shinobu Minazuki. It was serialized in Comic Rush from 2004 to 2007.
The story begins when the protagonist, Ryuuichi Otawa is rejected by the girl he likes because he's weak, and she only likes strong people. That night, while watching a martial arts tournament on TV, Ryuuichi absently wonders if he, too, could become strong. His mother overhears him and promptly introduces him to Iwao Kiryuu, president of a karate dojo and boarding house, and enrolls him in it without his assent.
What follows is a light-hearted Slice of Life journey of self-discovery, comedy, young love, and many, many of levels in badass.
OSU!! Full Contact contains the following tropes:
- Action Girl: Yumi and Kana, both of them the President's granddaughters. Yumi, in particular, is pretty much invincible.
- The Ace:
- Katsuhika, the dojo manager. Arguably the most handsome Bishōnen in the dojo,
- Yumi is another example, also crossing into an In-Universe Memetic Badass. She took out a shark during the beach episode, and it's implied during the winter training camp that the local bears might be terrified of her (along with every martial artist that knows her).
- Dissonant Serenity: Yumi. She never lets her Yamato Nadeshiko demeanor slip, and the only indication that she's upset is usually the black Battle Aura.
- Mr. Exposition: Whenever there's a new karate technique to be introduced, you can always rely on Katsushika to explain it.
- Old Master: Iwao, Kana and Yumi's grandfather. He always dresses in flower-print shirts, even in winter.
- One-Man Army: One of the dojo senpai challenges the 100-man Kumi-te. And succeeds. Katsuhika and at least one of the other dojo members also passed the Kumi-te previously.
- The Rival: also quite the Foil to Ryuuichi; he only learned Karate because his parents wanted him to, and hated it. Ryuuichi found this unforgivable, and then later defeated him in a match. Thus, their rivalry was born.
- Rule of Cool: In-Universe example: while he initially toyed with the idea of learning a martial art so he could try to impress girls, the reason that Ryuuichi ultimately chose to stay at the dojo and keep learning karate was because it's damned cool, and because he wants to see just how far he can go with it.
- Shipper on Deck: the number of characters that don't ship Kana x Ryuuichi by the end could be counted on one hand.
- The Stoic: multiple characters.
- Stone Wall: put an Actual Pacifist in a karate dojo, and this is what he trains up to be, so that he can defeat opponents without even needing to attack them. Hilariously, because the character is never in any matches, actually forgot about his training until Ryuuichi kept hurting himself during the match.
- Took a Level in Badass: a good half or so of the entire story is of Ryuuichi taking one level in badass after another. He still isn't a match for his assorted senpai, though, due to their having many more years of training and experience than he does.
- Training from Hell: averted by most over-the-top shonen standards, but subjecting total newbies to a 10km run as only the start of the daily physical conditioning probably qualifies.
- Troll: there are several trolls in this series, notably Katsushika, Fukujima, and Chiharu.
- Tsundere: Kana. She initially comes across as being more of the tsuntsun subtype, before growing into more of the deredere type.
- "Where Are They Now?" Epilogue
- Wholesome Crossdresser: there are two occasions where Fukujima has to crossdress - the second time, Ryuuichi and Shioyama have to crossdress with him.
