okay basically mc meets the manger of the solo leveling universe who needs someone to balance out the shadow lord when his heirs the last one standing.
so he sends mc in with a system similar to sung jin woo system but instead of shadows he calls upon there souls witch he have purified.
when he calls upon humanoid monsters they will rise looking the same in appearance.
1.9 meters tall wearing heavy looking armor while holding holding a sword or a bow with large light wings on there back. if he raises beast they will come out wearing holy armor looking more majestic or heroic.
mc will start off at the Same time as sung jin woo and will slowly earn the right to receive his class witch he will get on the same day a jin woo.
mc will go to the same system dungeon as jin woo so when they will meet but only see a figure of light or darkness.
mc at the end will team up to fight the dragon king.
