Titles are hard to make. If you plan on making an official manga/comic for publishing, make sure your title hasnt already been used, i know some comic artists here that have been sue'd for that even though they had no idea the title was already in use.

Best of luck

if thats the case the title can be changed. but some names are used by many different mangaka and authors but the story is different.
