Chapter 164: Chapter 164- Sanctum
The battle between evil and virtue has persisted for as long as one can remember.
The world can be changed, but each one has one thing in common, which is this unending struggle.
Demons are referred to as the carriers of evil, and angels are seen as the carriers of virtue and truth, which is true but not universal.
A being is prone to a particular nature due to three things:
First, the way they are raised.
Second, the environment in which they are raised.
Third, the mindset they have raised.
These three factors play a major role than one's own race, but due to the presence of a drawback inside the known demonic energy, the balance of evil always tilts in favor of demons.
This drawback corrupts their minds.
Even if they control it, the resulting aggression gradually erodes their sanity until they adapt to it and try to calm down their overall personality by directing it towards someone repulsive.
CREATORS' THOUGHTS

A4KL Conclusion:
Sanctum will be the foundation of Third volume, it's keys will lead Ryuk to meet Goddess Fela who resides in highest floor - Don't think I spoiled ur mood, I mentioned cause until the end of this Volume, whenever I mention Sanctum, it means I am talking about physical place/continent where saints live, also don't think much about that tower, it's cause there will be twist between these events, So, it's very far in future but for now.
1. Sanctum name is widely known by people as the place where saints reside but for Saints, that place is where gods reside with each floor having divine Artifacts which choose their own hosts, and can be accessed only by keys.
2. Maria was the one in chapter 2 (if u forgot, due to me always introducing new character, lmao), Ryuk has implanted demon seed which always causes her deadly pain whenever her divine energy try to make her Ascend( I will explain this in upcoming chaps).
U can comment if there is any doubt but for now, this volume will revolve around System's and Ryuk's battle.
Let's see what happens.
