If you like where the main character is strong than you'll like this one.
Similarities:
Both strong main leads.
It has a little bit of romance setting in it.
They both have to deal with powers to a certain extent.
Of course there are many differences such as the male lead in Mondaiji " just wants to have fun but in Densetsu " the male lead doesn't want any part of it. There is also the fact that they don't do it game style in Densetsu " but over all it has both many similarities and differences, but both are good.
