High School Exciting Story: Tough, or Koko Tekken-den TOUGH as it's known in Japan, is a Seinen manga written and illustrated by Tetsuya Saruwatari, who was also responsible for the artwork of the popular and notoriously violent manga Riki-Oh. HSE:Tough revolves around Kiichi Miyazawa, a 17 year old high school student who is the heir to the secret Nadashinkage-ryu fighting style that was passed down to him from his father Seiko. The Nadashikage-Ryu is a fighting style that utilizes the user's knowledge of and hitting of an opponent's vital organs and pressure points in such a way it can outright kill the opponent if the user isn't careful enough.

The series revolves around Kiichi's goal to become strong by defeating even stronger opponents in what are essentially Death Matches, though almost no one Kiichi fights actually dies (permanently anyway). The original manga ran in Young Jump from 1993 to 2003, and was compiled into 42 volumes. It was popular enough to get a 3 episode OVA adaptation titled Shootfighter Tekken, which covers a small fraction of the first arc of the manga, a sequel to the original manga simply titled "Tough" which is finished in 2012, and was succeed by the third part, Tough - The Man who succeeds the Dragon, which stars Ryuusei Nakamura, one of the many children of Kiryuu, and his venture into the world of martial arts to discover what happened to his father, who mysteriously disappeared.There are also multiple spinoffs centering around other major characters, such as Oton, which stars Seiko Miyazawa, Kiibou's father, and him finding himself against various opponents, whether they be psychopathic, pistol-wielding teenagers, Friendly Rivals, and even finding his help needed for going up against certain people, Fully Scarred Jinsei, starring Nagai Jinsei, a Breakout Character who was featured in Oton, and Devils x Devil - Kiryuu in Paris, a Rule of Cool zombie survival alternate universe starring Kiryuu Miyazawa, the brother of Seiko, finding himself fighting with guns, martial arts, and anything else he can find to survive against mutants called the No Hair Monkeys, who were once ordinary people mutated by the mysterious virus H4Q1.

  • Bitch in Sheep's Clothing: While at first Kichi appears Older and Wiser in Tough he still has the same Jerkass personality before the time skip.

    Oton: Could the ultimate technique in the nadashinkage arsenal be the eyepoke
  • Born in the Wrong Century: Heizo locks are an artform. No matter the opponent, he is always able to get inside his guard and perform a lock all in the blink of an eye. However this is the reason his wrestling career never took off as the spectators were never truly able to understand his techniques because they [[boring but practical weren’t very entertaining and were done lightning fast. However with the emergence of koppo, pancrase o jiujitsu, the spectators eyes are much sharper. If heiko was in his prime right now, he’s certainly be a superstar

  • Combat Clairvoyance: A specialty of the Nadashinkage Ryu.
  • Combat Pragmatist: The notion of illegal does not exist in the Nadashinkage style. Kichii isn’t above fighting dirty as in a fight the one who punches first is the one who wins. Even going for the groin. He has even resorted to biting his opponent Many characters have no problem using underhanded tactics even in sanctioned fights. Hell, both Oton & Kiichi have shown willingness to use underhanded tactics such as eye gouging and low blows.

He showed his redemption during his fight with Gen, knowing that jail wouldn’t make up for his sin, and even though he threw up before the match he stayed and fought and ended up having his carotid artery ruptured.
    • Kikuta is a very modest person, his breathing goes wild just by the pressure of a dangerous opponent’s glare, however in that weakness lies his strength. It’s because he thinks of his opponent as a superior being that he prepares the most elaborated strategy, and he tries to overcome the difference with exhaustive training.
      • The stress of the savageness of the Hyper Battle combined with Dogen's treat of selling his organs if he lost, turned him into this to the point that he vomited before every match.
    • Hyce Grancie gets so stressed before his matches that he's unable to urinate, but he gives Mark Hamilton a hell of a fight.
  • Crazy-Prepared:
    • Knowing that as a man of big business that he absolutely must go out in person to protect himself against the sniper Ozai wore a highly bullet resistant spectra guard helmet fitted with resin. The most advanced type of body armor there is, equipped with a spectra shield and special ceramic plate. His vehicle is a special made hummer limousine with equal bullet resistance to any other armored car. Its bullet resistant glass is 100cm thick, and cannot be destroyed by bazooka cannons or rocket launchers. And his business meeting was moved to a boat.
    • This turned out to be an aversion due to the Awesome, but Impractical of a lot of his decisions which allowed Yamada to Take a Third Option. For example the super-safe limousine was to big to go into any underground parking lots. So Ozai would have to walk thirty meters from the entrance to the car.
    • Then played straight as Oton had the forethought to make him wear terminal velocity.
  • Calling Your Attacks: Done by Kiibou and other characters, and in the T.D.K. arc, by the unseen announcer.
  • Comes Great Responsibility: Even though the Nadashinkageryu is a deadly style, having the power to kill someone comes with the responsibility of imposing on oneself some limits, not for one’s own benefit, but for the sake of justice and honor, and it’s a difficult task.
  • Combat Medic: Kiibou's aunt Yumiko, doesn't have any actual Nadashinkage techniques besides the ones meant to heal, but she's still rather strong, as she makes her entrance by rescuing Kiibou from a Yakuza wielding a gun by catching him by surprise, disarming him, and beating the crap out of him and and casually backhanding his buddy who was rising behind her.
  • Comically Missing the Point: Angered that Ukon kept comparing him to Kiryu, Kichi thinks about destroying him like Kiryu would.
  • The Corrupter: Shawn J. Akutsu, the boss of the Devil Factory, and recruiter for Kiba in his effort to find fighters to defeat the Nadashinkage Ryu. Just look at what he did to Remco.
  • Creepy Child:

  • Curbstomp Battle:
    • Kiichi handed out a couple of these over the course of the series.
    • Manji Shindou never took Aika’s father even remotely seriously and the outcome of the fight had been decided in an instant.
      • This is used as merely an excuse for his Ax Crazyness as fights to the death is taboo in the Shindo style, but when practitioners don’t have any other choice than to fight, crushing the opponent completely is the safest option.
  • Cut Short: The Original manga only had 6 volumes released in America by Viz before they stopped publishing it.
  • The Cynic: This seems to be a principle of the Nadashinkage.
    Oton: All human actions can be explained with one word self-satisfaction. If you’re training that hard to become stronger, it’s for your own personal fulfillment. You can extend it to self satisfaction. Even the most noble of the sacrifices is based on self-satisfaction. Jesus Christ himself was crucified for the sake of his people for self-satisfaction. That’s why you shouldn’t expect anything in return when you help someone. Because the moment you expect something, your act would become worthless.

  • Defeat Means Friendship: Kiichi seems to love befriending or becoming friendly rivals with the people he fights.

  • Desperately Looking for a Purpose in Life: Jet. It turns out being Kiryu’s son is his purpose in life.
    Jet: God doesn’t make mistakes, and somewhere deep in his heart, he knew that his life had a purpose, and that in time it would reveal itself to him.
  • Determinator: Pretty much all of the fighters, but Mikogami, a Yakuza boss, got violently mauled and lost his limbs from an attack from Kenshi Kaneshiro, as he had himself modified into a cyborg with a weaponized body so that he can kill him, and is continuing to upgrade the lethality of it.
    Mikogami: But even after losing my limbs, I did not die. But I will never give up on making this body the one that can kill him. And it’s for this goal and the goal alone that I will become stronger and stronger.

That doesn't mean he'll be soft with you if you're a villain.
  • No Good Deed Goes Unpunished: Before his match with Kiba, Oton pushed a drunk who had stumbled into the road out of the way of a car and was hit instead.
    • Yamatsu, a passionate man who believes that strength without justice is violence, and justice without strength is powerless, saved Oton as he was being attacked by a bunch of delinquents, and afterwards took him out for drinks as thanks.

  • Unskilled, but Strong: It is certain that a martial artist must work toward the ideal that flexibility often prevails over force and the small over the big. However it is the undeniable truth that a sturdy constitution has the advantage and in the world of combat techniques, its common sense that with a weight difference of 30 kilos (66 lb), the lighter combatant’s punch will be ineffective. Constitution surpasses technique. Even if it is possible to kill a bear or a tamed bull there is no man who can defeat an elephant with his bare hands.

  • Why Did It Have to Be Snakes?: Oton is afraid of flying.
