Nishimori, Hiroyuki

On their first day of class, first-year high school students Takashi Mitsuhashi and Shinji Itou immediately become friends. The duo seems to have quite a bit in common on the surface. Both of them aspire to emerge as delinquents upon entering their new school, and they begin to wear obnoxious haircuts to make them stand out from other teenagers.

However, despite being a feared pair, these two students actually have more differences than similarities. Itou wants to use his fists to protect the weak, earning respect and admiration from his classmates. On the other hand, Mitsuhashi strives to be the strongest in Japan—striking fear in anyone watching him.

Regardless of these dissimilarities, the two are notorious for their remarkable fighting abilities, and their friendship thrives when they come together to throw fists. Whether it be a fight against the good or the bad guys, nobody can win against these two unusual delinquents.

Kaito Kuroba, a normal teenage student whose father is often absent. When his father dies under mysterious circumstances, he is made aware of his father's secret identity; a famous international criminal known as International Criminal 1412: the Phantom Thief, and that he was murdered by a mysterious organization for refusing to aid them in retrieving the "Pandora Gem"; a mystical stone said to shed a "tear" during the passing of a particular comet (often called the 'Volley Comet'), the consumption of which bestows immortality. He vows to prevent the organization from gaining immortality, and assumes his father's identity as he begins his quest for the gem. His only clues as to the gem's location are that it glows red under the full moon and that it is a doublet: a gem hidden within a larger gem. Thus, it would have to be a relatively large one with a bizarre history, and always stored in a place that never receives moonlight. He thus researches and steals famous priceless gems with odd histories from incredibly well-defended areas, and always returns them after the very next full moon.

Kinnikuman (a.k.a. Kinniku Suguru) is a cowardly, clumsy, moronic, gyuudon-devouring excuse for a superhero (or Choujin)... who just happens to be the prince of an alien planet. But despite his pathetic appearance, he is very honorable and can become quite powerful when he needs to be. With his sidekick Meat-kun and fellow Choujin's Terryman and Ramenman there to help him, Suguru quests to become the greatest Choujin on the planet. Whether with a combination of tremendous heart and stamina (The Burning Inner Strength) or the "Power of Friendship," Kinnikuman frequently defeats villians 10 times more powerful than him and often causes his enemies to have a change of heart and join him. Though he seems destined to be an idiot forever, slowly but surely Kinnikuman becomes worthy of the title "Hero."
