Very well. Buckle up. It's going to be a ride. /dons on teacher's glass and brings out whiteboard
So basically, Esper/Guide verse is a genre that follows closely with alpha/omega verse with a few different caveat than omegaverse.
Esper is someone who has powers, mostly combative powers like flame manipulation, etc,etc. This combative power makes them powerful, however, they have a very significant drawback. They will accumulate bad 'energy' that can make them go insane and be incredibly destructive.
This is where guide comes in. Guide will take away that 'bad energy' and soothe the esper. Esper won't have to worry about going insane again when they have guide to dispell the bad energy for them.
Now as to how they dispell the 'bad energy'? A simple answer: Physical intimacy and sexual intercourse.
Oh and esper/guide typically have ranks. Guides can only guide the espers if they are compatible.
Which brings us to compability rate. To ensure both the guide and esper wellbeing (more so with espers since espers need to use their power to kill monsters), the compability rate must be high, at least 50%. This is to ensure their energy did not reject with each other during guiding.
The higher the compability rate, the higher the chance the guide will be sucessful.
So, that conclude our crash course on esper/guide verse. Any question?
