Guideverses are where the setting usually has monsters and dungeons and people start developing powers to defeat those creatures. I’m the beginning it sounds like your typical “solo leveling” type dungeon and hunters setting but instead the ones with mental, physical, or magical abilities are called espers. Espers are like hunters because the have powers but they have one flaw. Their bodies aren’t built to handle the strain because they’re humans and sometimes that leads to them getting sick and suffering or them having mental breaks and going on a rampage or them turning into monsters. Guides are the beings that regulate and calm their abilities. They are kind of like healers only able to help espers. Usually they have classes and have certain people they connect better with. Guides and espera can be exclusive or pair with many people. (Most romance ones are exclusive) guides and espers are not always romantic and can have many times of relationships. In some universes the guide can guide them from far away, by touching their hand, or by hugging. Some other universes are more intimate and include sex. Anyway I hope this helps!
It's basically differentiate on how authors wants to execute story with concept of guidvesere I will explain simply --
- Esper - is a person who has strongest powers (like fire , telepathy, water or things control type) they are like heroes in the world of monsters like there are monsters they fight government organize them and to control their power or not to let them rampage they need a person who will give them mind peace or calamity to their powers. Sometime esper without a guide become a empty shell so without his guide ,esper is in strongest needs for a guide.
- Guide - is a person who is meant to be with esper but his destination is simple he gives sense of calmness to his esper that's his work is not let to his esper rampage.
They don't become partners eventually cuz they are also divided in hierarchical order like S-rank esper are strongest they need same rank of guide to supervise them sometimes test are made to check if they suite each other if they suite that means they compadible enough strongest the Esper and match the strongest guide they needs to intimate with each other give esper sense of security or power control.
Sometimes guide playes the role of archive wheel for esper who is out of control so it's easier to handle him so people around them don't get injured. For an esper guide become his weakness and it's advantages or disadvantages both.
mostly this guidevese getting popular for making esper a dangerous person who are crazy mostly those are semes, they needs controler so it's important for them to have his own guide.
some guidverse also follow imprinting concept so they don't have to share each other with others especially for esper who are possesive or obsessive type.
can someone explain in depth guideverse? ( ̄∇ ̄")
