Naofumi Iwatani (In Japanese: 岩谷尚文, Iwatani Naofumi), often referred to as the Shield Hero (In Japanese: 盾の勇者, Tate no Yuusha) is the titular main protagonist of the light novel, manga and anime series The Rising of the Shield Hero. He also appears as a significant supporting character in the second season of Isekai Quartet, a crossover anime featuring characters from the "Isekai" genre of anime.

Initially a layabout from Japan, Naofumi was transported to another world by the Church of the Three Heroes alongside three other Japanese men. These four Japanese men became the four legendary cardinal heroes, each wielding a legendary weapon.

Naofumi was given the Legendary Shield, becoming the latest Shield Hero. Unfortunately, the possession of the Shield gave Naofumi a natural disadvantage, as he didn't have any means of offense. To make matters worse, the Church and part of the monarchy held a prejudice against the Shield Hero and defamed him as a pariah to the kingdom.

He is voiced by Kaito Ishikawa in the Japanese version of the anime, and by Billy Kameez in the English version of the anime.


At first, Naofumi was a kind and trusting man. However, after being framed and hated by the country, he grew bitter and resentful. He hates Malty and her father for their cruelty, and the other heroes for their incompetence.

After Raphtalia became his slave and joined his party, he began to go back to his kinder nature, albeit still somewhat bitter.

  • Naofumi has a similarity of his Arifureta counterpart, Hajime Nagumo:
    • They were once weak-willed from the start.
    • They become the strongest when the journey has begun (Although Hajime strength is stronger than Naofumi in the Anime and Naofumi is stronger than Hajime in the Web Novel).
    • They were betrayed but survived from their supposed death.
    • They became killers to kill anyone who gets in their ways or harming his comrades.
    • They've abandoned their original personality of kindness and moralities to adopt a new personality of anger and hatred (Naofumi is anger, distrustful, and hostility, while Hajime is ruthless, unstable, and sadistic).
    • They defeated their abusers (Naofumi defeated Motoyasu before he redeemed himself, while Hajime killed Hiyama).
    • They killed their tormentors (Naofumi had Malty to be executed by burning her at the stake, and Hajime fed Daisuke Hiyama to monsters).

    • They have a lot of lovers from their own harems.

  • Their life changed entirely when they were punished for the crimes that they did not commit.
  • Both of them treated their female slaves like their own daughters. 
  • But their slaves loved them as much as a woman loves a man. (Haydeé fell for Edmond and desires to be seen as a lover, not a daughter, Raphtalia also fell for Naofumi, and she desires to be with Naofumi)
  • They were deserted by the first woman they met. (Malty was the first woman who approached Naofumi in Melromac, and then she betrayed him. Meanwhile, Mercedes was the first woman who is betrothed to him, and she ended up with another man.)
  • Naofumi and Edmond started out as a naive person. However, their personality changed drastically due to betrayal. 
  • Naofumi and the Count were betrayed by their "allies."
  • Naofumi and the Count have rage issues that they have difficulty in distinguishing between those who have wronged him and the innocent bystanders.
