If your family died today, what would you do? Mourn for a while and let them go? Devote your life to doing what would make them proud? Maybe find a way to turn back time and save them? Well, for Shadow Master, those just won't cut it.

There's a legendary artifact called the Soul Ring. By putting a gem on the ring, a person can gain Soul Weapons. By killing 1000 people with the Soul Weapons, they get to revive someone of their choice. There are extra factors as well.

1. When a person's soul is taken, the body becomes a Shadow Vessel. If the vessel kills someone, the victim also counts towards the Soul Ring count.

2. If the gem on the ring is destroyed, all the souls are released, but only those that were killed after the last summon.

3. The ring itself can't be destroyed, so another person could put a gem in it and start the chaos again.

You are a student at Light Academy which focuses on combating these enemies and locating the Soul Ring. You can be part of 15 classes, each with their own skill set and weapon.
