In the year 2020 there was a massive virus out break. This outbreak spread across the globe and no man, woman child or animal was spared
When someone became an infected there bodies went through three phases. The first phase was just a lite cold. The second phase was a high fever and cramps. The third and last stage was the most dangerous and painful. The body would begin to size up and pour black pus from every pore. If the infected's body was to weak they died. But if they survived, they gained the system.
For humans the system gave the infected now turned host the power to level up, see their physical stats and change their physical stats through skill points received every level, manipulate the mysterious power called mana and manifest their soul in the form of a weapon with which they could channel skills on themselves or their enemies.
Not all soul weapons are the same. For every host the weapon's power and appearance changed (The power of a weapon is how much mana it can channel). The appearance and initial power depend upon age and life experience of the host. If the host summoned their weapon to early the weapon would be weak. The same was true if you waited to long.
Soul weapons are graded on a scale of G to A with G being the lowest. The weapon level was determined on the power and skills of the weapon.
Our story begins with our protagonist William waking up to go to school on conjuring day. The day when every school around the globe has their students conjure their soul weapon.
