I am looking for a manga/manhwa that I read 30 years ago (around 1992 or 1993) in South Korea.
What I remember is this:
the protagonist seems to be a djinn/jinn or similar entity but with an outward appearance of a slender boy. He seems to be trying to rescue a girl who might have gotten abducted by the antagonist - a being similar to the protagonist but initially much more powerful. In order to reach him and the girl, the protagonist has to defeat powerful foes who possess unique fighting abilities (unsure about that). The protagonist seems to have to advance from one level to the next (I don't know if it is another dimension or a structure such as a tower). Floor by floor (or plane, or level) the enemies the boy is forced to defeat get stronger or show more surprising abilities/attacks (again, unsure).
The protagonist's most powerful attack seems to be a sort of "black hole" spell/attack/ability. He puts both his fists together in front of him and between his fists he creates a sort of "black sphere" or "black hole". I am not sure, but the main antagonist also seems to be able to generate this type of spell/attack but can create two or more at the same time, which initially renders him stronger than the protagonist. Of course, the djinn/jinn boy still manages to somehow win and free the girl (I think...).
In my mind, he, the enemies on every floor/plane and the main antagonist seem to have been djinn/jinn, at least I remember them addressing each other in such terms, but it could very well be that this is just a fabrication of my own mind. Likewise, the aesthetics also seem to have had an oriental/Middle Eastern touch, but again, that could just be a product of my own imagination.
It was written in Korean, however, I don't know if it was a translation from a Japanese manga or an original manhwa from a Korean artist and author.
The art style was definitely manga/manhwa, not western comic and it was in black and white, no colour.
