I whole heartily agree with Chierii. The Character element is done perfectly in this series. The anime did a great job bringing the characters to life. Bell-san has it rough being a level 3 rookie. Although he is kinda oblivious to why he leveled up so fast. However, this doesn't deter Bell from his determination and convictions. He will do what it takes to protect his familia and catch up to Ais Wallenstein. Being popular with the ladies is great for Bell, although bad for Hestia, which makes Dungeon Ni a lot of laughs, full of feels and drama. I want the anime to be dubbed soon.Unless it is and i can't find it.
I recommend reading this and watching the anime adaptation. You might like both.
