This series basically follow an overpowered protagonist that has to maintain a dungeon tower, together with some overpowered subordinates. I personally love the story developments this one, because things slowly grow in scale as the existence of his dungeon tower garner more and more attention (mainly politically). The romance especially, is really wholesome (and lewd). The relationships between the protagonist and the heroines are adorable with ero-scenes here and there. The protagonist goes quite far in helping different heroines with their issues, the heroines also work towards supporting the protagonist in every way they can as well. Relationships and dynamics are developing in a gooddirection between different characters because of this.
