Coll was about to go home after a headache inducing school, unfortunately... Or fortunately for him, he was thrown in an ever so familiar dungeon.
Clearing the dungeon, he was transported back to the real world with the ability to go in and out of it.
What to expect:
-evolution.
-dungeon delving with a side of slice of life.
-gender fluid MC.
-gore and violence.
-r18? It's there but, not the main focus.
-may include barely distinguishable writer's kink. For example: futa, tentacles and other similar kink.
