Before anyone asks, this was a collab that I worked on with my buddy Silverlion12K that I got permission to reupload on my channel by him.
All Heroes come in different shapes and sizes. Many fight through challenges that will make them stronger in t...
Ok so for everyone to understand some base information about Shield Hero so everyone has some knowledge into what exactly are some limitations and/or major parts of this story to know.
Waves of Catastrophe/Calamity(translation varies)- World Ending phenomenon that happen when two universes connect with one another. The effect of this creates cracks where the two worlds intersect and pull in monsters. If the boss monster is not defeated as quickly as possible, the world as a whole will be destroyed and absorbed into the other world, making it nonexistent.
Cardinal Weapons- These are one of four different weapons given to four different people. These have multiple abilities to use such as means to upgrade, create and enhance weapons. The limits of these weapons varies solely on it's holder and can create systems to become stronger if certain criteria are right. As an example, a proficiency system which requires one to constantly use a weapon to make you more skilled and increase it's abilities can be given, but one without some kind of limitation such as 'give me a system to make me better with little effort' cannot. The user of said weapon cannot be controlled unwillingly or enslaved, but being manipulated through agreeing to something is not out of the question.
Drawbacks to the Cardinal weapon are one cannot use any weapon outside of the set weapon you have. So if you hold a Spear Cardinal Weapon, you cannot use any weapon outside of the spear or suffer a large shock in violation of said rule. Exceptions such as using knives as a tool for cooking are able to be made, but you cannot use it to fight. One cannot also grow stronger if one or more Cardinal weapons are in a set radius. In addition to not being able to use another weapon, the Cardinal Weapon cannot be taken off or removed from the body. It can only be moved to different parts such as changing what arm the shield is on. The user of a Cardinal Weapon cannot travel between worlds due to them being obligated to the world they are summoned to. Exceptions can only happen with a being high enough to hold significant status in the world. An example would be a creature who's sole purpose is to protect the world and is revered as this for most of recorded existence. Cardinal Heroes must be summoned to the world they are in by the spirit of the weapon. If one was to meet an untimely end, a new Cardinal Hero cannot be brought in unless the remaining three perish as well. As such, if the Sword Cardinal Hero were to die, a new one cannot be summoned until all three of the remaining in the set do as well.
Vassal Weapons- A weapon created as an assistance to the Cardinal Hero. For each Cardinal Weapon, two Vassal Weapons are in place in order to assist. Though they follow very similar guidelines as the Cardinal, the Vassal weapon does not have to be summoned from another world and can be replaced immediately after the former passes so long as a capable wielder exists in the world. If one does not, it will wait until one that is worthy is present for it to choose.
Drawbacks of the Vassal Weapon are similar to the Cardinal with the limit of how many Vassal Weapons around before hindering growth being two. As such, a Cardinal and two Vassal weapons can be in close proximity, but never three Vassal weapons.
Added bonus of the Vassal weapon to accommodate the growth limitation, the Vassal Weapon holder can travel between worlds without the need of authorization from a supreme being of said world. This allows them to get stronger in another world while also having the combined strength of both worlds during the Wave to better assist in it.
Curse Series- A special series that is given to Cardinal and Vassal weapon holders. This acts as a double edged sword that will both give you immense strength, but notable drawbacks after. This series has weapons related to each of the seven sins in religion.
To awaken this series, one must succumb to a world shattering event. One in which their heart and mind are broken to a state of a psychological breakdown. Once the series is activated, it will forcibly alter your emotions to relate closer to that sin and entice you to use it more and more. Though the damage is hard to fix, it is not irreversible and as such can be fixed if all the pieces are picked up again.
Alright. Now that some information about Shield Hero is done for us to understand how certain things work, let's get into the differences in this story.
First and foremost, Cardinal Weapons due to the way the world evolved, became quirks which the world has been unable to gain for several generations of quirks. This has pushed the world into a bit of a crisis trying to find them or holders of the Vassal Weapons(no change on them and how the Vassal Weapons find holders).
Due to the fact the world is struggling to find Cardinal and Vassal Heroes, the world powers as a whole agreed to find any and all candidates in secret and train them to fight the Waves in secret as well. Since they're handled with only high ranking powers handling the threat, all acts done during the Waves are never spoken of to the general public. In short, people do good things here and they don't get rewarded or praised by the public.
Thanks to an authorization as mentioned above, Naofumi's party along with Kizuna's and the other three heroes are brought into the world of MHA and are doing what they can to stop them while under the veil of being a pro hero group called Seayetto. (minor series spoiler here) Atla was able to be brought back thanks to Naofumi's feats in the previous world and is part of the pro group.
Now onto Izuku's bio.
Izuku Midoriya
Oops! This image does not follow our content guidelines. To continue publishing, please remove it or upload a different image.
Age: 14(start of the actual story)
Quirk: Cardinal Fist
One of the four Cardinal Weapons of the world. Has the ability to grow with the wielder and gives an RPG system to the user. Is unable to use any other weapon and will be empowered primarily by the wielder's physical and mental capability.
Current weapons(When awakens): Small Gauntlets Wrath Gauntlets
Personality:
Due to not awakening his quirk until a later age due to a decision Inko and their doctor made, Izuku never realized he had a quirk. Thanks to this, the quirk did not manifest until Izuku's mental breakdown with All Might and the awakening of the Curse Series. Thanks to awakening this, he's become somewhat cold and distant to most and holds notable distain at the fact he was ridiculed for something he actually had but didn't know. Thanks to his need to be active in the Waves however, he has shown a slight higher maturity compared to most due to how the world requires it from him. Is kind to those he looks at as friends and teachers.
