Naofumi Iwatani [9F33YK- AMKS]

Naofumi has short black hair that spikes in all directions and sharp green eyes. He often wears a scowl on his face because of his cynical outlook towards the world, but he does express gratitude from time to time. The armor he primarily wears is Barbarian Armor +3, which has gone through numerous upgrades and transformations. Depending on the situation, he may switch to different sets of armor or clothing. The weapon in his possession is the Legendary Shield, which was granted to him when he was summoned to another world.

Being left near-penniless, falsely accused as a criminal, and hated by nearly everyone, Naofumi became extremely distrustful towards everyone and cynical about life. He could not trust anyone and started to assume that others were trying to get something from him. The result of the Princess's betrayal has left him in an almost permanent state of anger and hostility, which he masks behind a calm and level-headed personality. This mentality bites him back as he unknowingly pushes away genuine supporters of the Shield Hero and Siltvelt envoys. Unfortunately, being a Shield Hero meant that Naofumi was essentially useless by himself, which forced him to eventually seek help. He was convinced to get a slave - someone who could not betray him - so he eventually finds Raphtalia. Naofumi treats her deadly illness and teaches her to fight. After spending time with Raphtalia, and eventually Filo, Naofumi starts to heal mentally and trust his close companions. However, this is a long process and Naofumi is still unable to fully trust or be intimate with others. Unlocking the curse series weapon Shield of Wrath also placed a block on his psyche which prevented him from empathizing with others. After losing nearly everything, Naofumi deeply values what he has built up since being summoned, especially his relationships. Therefore, he is protective of people like Raphtalia. It is also shown several times that Naofumi is at his most vulnerable when he loses someone close to him. This can be seen when Naofumi thought he had lost Raphtalia after losing the Duel with Motoyasu, and when he was separated from Raphtalia and the rest of his party he traveled to Glass' World. He was even willing to sacrifice his life to save his friends such as when they were battling against the Phoenix or Takt. Naofumi is a pragmatist and is willing to take some unconventional measures to meet his goals. For example, after saving Rishia and Keel, he offers both of them to be his slave since the shield helps improves a persons growth and stats. Once becoming governor of the territory which includes Raphtalia's destroyed village, Lurolona Village, Naofumi purchases slaves to be villagers. He justifies this saying that this will give them a better life and that it will help them gain independence. Due to their good treatment and their respect of Naofumi, the children end up adoring him. At one point, Rishia wonders if Naofumi's commitment to the villagers make him their slave instead of the other way around. Subconsciously, Naofumi often feels unworthy of what he has and tries to deny certain things. This can be seen in his constant ignoring of Raphtalia's romantic feelings due to feeling unworthy of her. This also shows in his addiction to Raph-chan which - in his own words - he only likes so much due to its resemblance to Raphtalia herself. He often feels vulnerable about certain actions he takes which can be seen often when Raphtalia points out the absurdity of some of them. He has feelings for Raphtalia for many reasons, including her being the light that brought him out of the darkness of his life.He considers her a hero for being the one person to stay by his side even after everyone despised him.
