All honesty it's so hard to come up with weak to strong MC plot. Though I have made some my imagination stops in continuing them.
Some MC's of my other novels are just human with no power just fighting abilities.
Others actually growing stronger slowly than just becoming OP in an instant from being weak. Which too ends up not continuing.
Then again even some not to OP mc's are going to be given a challenge. To where they actually feel challenged and bleed for once.
Welp this FF will be the same as many OP one's. Though MC is actually 'weak' not knowing the full extent of his powers. So in a way it's kinda weak to strong.
Now I want to mention harem on this FF will come like a bit late right since, I want the MC to grow. Lots of interesting things will be written in this FF.
Expect as you can see in the cover jungle juice, Kyochuu Rettou, Ingoshima, parasite,super ball girls and other things. Kind of horror-ish and gore being ingoshimaI with Kyochuu Rettou want to add since I haven't had my toes sink into those type of generes that these mangas have.
As you can see alien invasions mangas also interest me to put in.
Majority of the mangas are a long read so I would revisit them to gather the knowledge i need. Might add even more sort of invasions type anime, manga or movie. For now these manga's, anime and the such combined and probably never seen before. Hopefully this is to your liking,
