I hope this review can be useful. English is not my nacional language so It will probably has some mistakes. Story: The main character is Vanir, The Duke of Hell and one of the Demon King Generals. It tells some little adventures that Vanir had in Axel (the city of noob adventures). The most interesting thing about the story is how Wiz and Vanir met. Characters: Vanir is a great character, one of my favorites characters of the series, his special power and his seek to negative emotions makes the light novel extremely funny to read. This novel explore some secondary characters such as Yunyun, Dust, Luna,Iris and even Agua and Wiz.

Art: It's great such as the main Novel.

Enjoyment: The first and half of second chapters were boring. However, after that the novel became hilarious.

Overall: I recommend this Light novel for the big fans of konosuba who have read the main novel and the Megumin's Spin-off.
