Wrath Series (Web Novel)

The Shield of Anger is the first shield in the Curse Series and is claimed in 『Chapter 22』 of the web novel after losing a duel to Kitamura Motoyasu partially due to the unfair assistance from Malty Melromarc. It is unlocked after seething rage from the very depths of the body envelops Naofumi and the requirements to unlock the Curse Series are met. It's name is varied but is commonly called the Wrath Shield. Other names include the Shield of Fury, Mortar Shield, and Killer Shield (the exact name is kinda lost in translation I believe).

In 『Chapter 52』 of the web novel Naofumi is forced to use the Shield of Anger in order to defeat Glass. When he activates it the last memory of the dragon that Ren killed is projected into Naofumi. Through this he is able to understand the anger and humiliation the dragon felt from losing to a human. He says it was far beyond his imagination. He watches as a part of the chest and the middle of the forehead is pierced by the Hero of the Sword. The shape of the shield changes from one surrounded by flame to one that resembles a dragon. Furthermore, in conjunction with the shield, Barbarian Armour +1 also changed. The Rider Suit changes to look like a Jet-Black Dragon. Whith the unlocking of the new shield the ability 「Iron Maiden」 is unlocked. Using 「Iron Maiden」 will drain all of the user's SP and leave them feeling drained.

In 『Chapter 72』, while fighting the pope, Naofumi and company are being pushed back by a replication of a legendary hero’s weapons possessed by the pope. The replica is able to transform into any of the Four Heavenly Weapons but it is incapable of growing any more powerful that its current state. With the help of Firo and Raphtalia, Naofumi is able to control the anger of the dragon's core in the Shield of Anger Ⅱ and direct it towards his enemy. The Shield of Anger Ⅱ’s dragon-like figure has becomes even more ominous compared to before. The shield's dragon features morph to be more devil-like and the horns curl around. After building up the anger the ability 「Blutopfer」 (which means blood sacrifice in German) is unlocked. 「Blutopfer」 is like a steel bear trap that has multiple layers. It looks like the ground grew a shark’s mouth, with the target in the middle. Although it is extremely powerful 「Blutopfer」 is also very taxing. Using it drains the users blood and curses them, cutting all of the users stats by 30% except for defense (reference 『Chapter 74』) until the curse is cured completely. In addition to that, after a using it the user will be left unconscious for at least a day if treated properly and may feel lethargic when they regain consciousnesses. If they are not treated in a timely manner, they will suffer death.

In 『Chapter 116』 of the web novel takes the time to strengthening Wrath Shield Ⅲ. He discovers that this shield cannot perform item, spirit and status enchantments however it's abilities still improved tremendously.
