New to this kind of thing so I'll just be quick with this, the main things I remember from the manga is that the main character is a male and is in school and is being bullied, one day he obtains the ability to create doors that lead to his own pocket dimension by a succubus. He uses this power to exact revenge on his bullies. If anyone can help it is very much appreciated.

That's sounds like ntrevenge or kankin ou Both have the same kinda premise
