What to expect:
TL;DR Hai to Gensou no Grimgar is a fresh take on the "Stuck in a video game" type of story. This novel gives you a realistic take on what is likely to happen if one was transported into an MMO-like world. The world is brutal, unforgiving. Character are realistically cautious and take a "slow and steady wins the race" type of approach. The author constantly reminds you what happens when one is careless in this world. If character development is important to you, and you want a realistic approach to the "trapped in another world" genre, then you will certainly enjoy this book.

Characters:
The characters well written. Every character is human-like and has unique thoughts and feelings that people can identify with. For better or worse, characters can and will anger you. However, this is intentional as it is used for character growth and development. The characters and how they develop, is easily one of the best things about these novels.

Story: While the story starts off as a generic transported to another world this novel distinguishes itself on its realistic approach. The characters aren't gifted, they aren't given some super special power. They start mediocre and slowly become less mediocre. While world building does occur, it is done in a way of discovery. Less in a way of being taught, and more in a child exploring the neighborhood type of way.

Enjoyment: Between the good story and the excellent character development, this is definitely a great read.
