Manga: Iron Knight

Iron Knight is a manga by Tomohiro Yagi about a boy named Teppei living in a world where a mysterious disease called the "Goblin virus" wreaks havoc across Japan. Waking up in the middle of his now ruined city, he tries to find out what happened. After encountering a man with the goblin virus, he finds out he too has it. But inspired by how his father, a policeman who tried his hardest to protect the city, he uses his new power to protect humanity as the Iron Knight.

Originally a oneshot, it now is a part of Weekly Shounen Jump.

Compare other manga like Zetman or Devilman.

Contains examples of:

  • After the End: The series starts the day of the apocalypse, with reports of strange bodies in the water and gang violence in the streets. As Teppei is walking home, he falls unconscious somehow, and wakes up hours later to find the entire city on fire.
  • Calling Your Attacks: Played with. Teppei, being a young boy, tries to call his attacks during battles because it's cool and he actually believes doing that empowers the attack, but quickly realizes it's difficult to do it when battling a group of monsters.
  • Childhood Friend Romance: Teppei and Himegami.
  • Childhood Marriage Promise: First chapter, guess who.
  • Chronic Hero Syndrome: Teppei, as he looks up to his police officer father. He even promised his dead mother to protect everyone.
  • Clingy Jealous Girl: Himegami was not happy to see a female shop owner complement Teppei.
  • Conditioned to Accept Horror: By chapter 2, Teppei does not flinch when seeing corpses. He was calm-headed enough to see that the corpses in chapter 2 were in an unusual condition.
  • Everyone Can See It: Teppei and Himegami. When they were ten, everyone seemed to know.
  • Everybody's Dead, Dave: Teppei gets shown this by the criminal his dad took in that morning.
  • Heroic RROD: Teppei learns that if he uses his power too much, he literally starts to melt himself.
  • Heroic Willpower: After Teppei wins his first fight, he's so exhausted he can barely stand. Then more goblins round the corner...
  • Hot Blade: Teppei develops this as a counter to an enemy's immense size and regenerative ability.
  • I Should Have Been Better: Teppei runs into this, in chapter 2. He finds fresh corpses of a family and feels that if he hadn't taken the long way, maybe he could have saved them. He was scared of using his powers too much (and the consequences) and avoided as many demons as possible.
  • Like Parent, Like Spouse: The shop owners in chapter one, say that Teppei has the same taste in women as his father.
  • Made of Iron: Teppei is a literal example.
  • The Magic Comes Back: Karasuba claims that the monsters of the world went into some form of hibernation hundreds or thousands of years ago, and now have returned to reclaim their place at the top of the food chain.
  • Playing with Fire: Teppei has the ability to shoot fire balls.
  • Required Secondary Powers: Unfortunately for Teppei, he does not posses immunity to fire and using too much of his power can result in increasing his body temperature too much.
  • Smug Snake: Karasuba is extremely arrogant over his powers, and how superior he was to even the other monsters. He is killed by Teppei before the end of the first chapter.
  • Time Skip: A month passes between chapters 1 and 2. Teppei spent that time killing monsters in the general area and looking for survivors. He didn't find any, but he personally cremated every corpse he came across.
  • Transhuman Treachery: Teppei is apparently the first monster to not turn on humanity the second he awakened to his monster form. Karasuba seems to believe that pure monsters (like Teppei) are just ravening beasts with no control, but Teppei obviously proves that wrong.
