A fun adventure

I finished this web novel a while back, and I intended to review it. However, I got distracted by life and I am only doing so now.

This is a solid 'returner' story where the protagonist finishes his duty as a hero and returns to Earth... only to find that it is an alternate world where dungeons have manifested on Earth in classic litrpg apocalypse style.

This story is remarkable for a number of things, including its surprising emotional depth, good humor, and somewhat excessive ecchi/explicit content. Being an experienced eroge player, this actually doesn't bother me at all, but for those who want a 'clean' story with innocent romance, this isn't really a good choice. The heroines are erotic and lustful, and the protagonist is just as bad.

The upside is that the good humor and interesting turns and twists last right up to the very end, making it a great story to kill time with.
