Get back into the horny jail! *BONK*
When people see the word harem or ecchi, people would immediately deem the anime as low quality fan service. While they arent wrong, there are many factor to people enjoyment when watching anime.
As usual, I set super low expectation when watching this kind of anime. I would be honest to say I hooked at beginning of the series. While it can be generic, something about the protagonist trying to learn about the world. He took like 3 episodes to finally able to buy him dream slave. In this world, is not even wrong to use the slave for lewd purpose. Story then revolved around both of them trying to go deeper dungeon to earn money, while improving their living condition.
For me, the story dropped in quality in the middle. Since it focused on repetitive dungeon diving, the plot halt to a simple of going dungeon, buying new stuff, sex scenes and repeat for several episodes. Those combat / skill mechanic exploration used at beginning arent being focused much afterward and more toward their romantic interation. But biggest issue for me is despite showing many girls in the poster, the plot moved way too slow and they only added 2nd girl at episode 11.
Uhm, even for harem / ecchi standard i think this is really missed opportunity. It is almost the story can only become better in 2nd season with more girls. I suggest skip this unless you really horny, there are many better fan service anime out there.
