Henry stared at the strange green translucent window in confusion. It displayed the words "Synchronization complete. The Granter of Systems, one of the six Guardians of Infinity, has granted you a system. The Demon Slayer System has been initiated.". It also had a female monotone voice reading it aloud. He assumed this must have been the Voice of the World the priest said Unique Energy users could hear. However, there were some things he did not understand, such as who these "Granter of Systems" or "Guardians of Infinity" were. He then wished for the window to disappear, so that it could stop blocking his vision. Once he did, the window did disappear, but another appeared in its place.
[The Demon Slaying system is currently only a guidance type system, which means no real power is provided by it, and that its only job is to provide a metric for your power and guide you towards your growth. Would you like to experience the tutorial?]
Henry read the new window.
"It only shows me how powerful I am? And "currently", eh? Does that mean it will provide me power in the future? Interesting. Also, a tutorial, huh? Alright, sure."
[Beginning Tutorial]
The window was replaced once again. This one had four things on it.
To the left was a picture of the planet's only Sword Saint, Kim Tae-Hyuk, holding his sword. Henry recognized him as he had seen his statue in the Weapon Master Association branch in Wolfberg back when he took his exam to become a Squire level swordsman. The picture had the words "Weapon Mastery" written beneath it.
In the middle was a picture of Henry himself holding his sword with jade green Demon Slaying Energy wrapped around it. It had the words "Demon Slaying Energy" written beneath it.
To the right was another image of Henry, this time him pushing his sword into the chest of a demon. It had "Quests" written under it.
In the top right was a small bell icon that did not have anything written under it.
Another window appeared next to this window.

Henry read this and tried to visualize the window disappearing, and both windows suddenly disappeared.
"Hm..Convenient." Henry then tried to imagine the windows appearing.

[Weapon Mastery:
Sword Mastery Level: Mid Tier Squire Level, 470/1000 Exp
Suggestions: 1-Improve your Sword Mastery to Knight level
2-Achieve Squire Level mastery of either bows/ Magitech guns]
Henry watched this, interested.
"Knight level, eh? If only it was that easy. I've been a soldier for so many years and couldn't reach that level. Well, I can only hope my training with the old demon hunter Father Rico suggested could push me forwards. Also, what's "Exp"?"

"I see. I'm not even surprised you answered. I mean, you literally respond to my thoughts."
[Tutorial, part 3: Demon Slaying Energy:
Demon Slaying Energy is an aura-based Unique Energy created through your intense desire to vanquish all demons, avenge your wife and save your daughter. It grows stronger the more demons it kills.

The system can help you track its power through levels and show you what level of aura it is currently equal to.
Missions:
-open Demon Slaying Energy menu (incomplete)
-see the level up suggestions (incomplete)]
Henry willed the Demon Slaying Energy menu into opening.
[Demon Slaying Energy level 1, 0/100 Exp
level up suggestions: Head to the 72nd region of Hell, ruled by demon king Andromalius, the weakest of the higher demons and hunt the demons there.]
"A demon king? 72nd circle? Even the system wants me to go to Hell, I see. Alright, I'll head there once I reach Knight Level."

"Huh? My what? What's with these black boxes? Even the voice read them as "error". Anyways, let's open the quest menu."
[Quests:

Seeing these quests, Henry was greatly shocked. "This thing wants me to kill al 72 demon kings?! Who does it think I am?"

The small bell icon in the top right is notifications, and the system will use it to notify you of important changes. May the blessing of the Core be with you.]
"So, whatever this error thing is, it increases by killing demons, and increasing it will expand the system. Alright, at least my next task is clear now. I do still have to sleep, but I'll contact Father Rico once I wake up."
With this, Henry wrapped himself with his blanket and fell asleep, having had the longest day in his life.
