If you see the first episode of this anime, maybe you will ask yourself:
"Why are they wasting so much time before letting the MC enter the fanatsy world? It is irrelevant anyways!"

After watching the other episodes, you will realise why that is: Suzuki Ichirou, the 29-year-old hard-working programmer is on his "Death March" and after another hard days and nights he is going to sleep and starts to dream.
This just perfektely fits the rest of the story. If I wanted to describe the whole series with few words and without any spoilers I would say: The story is like a good dream:

• happy-go-lucky all the way long
• generic but well-made beautiful setting
• the dreamer is an overpowered hero, doing hero-things
• meets nice people and gathers them around him

To be honest: This is a really simple story-concept - do not expect anything deep or outstanding. It is just a nice dream. But if you are interested in Ichirou's dream, you will get rewarded.

The art is great, always fits the atmosphere and the series in all. They really made everything fit the fanatsy-RPG style. What I especially liked is the GUI which Ichirou interacts with very frequently. This is an aspect where the series sets itself apart from many other Isekai-Game Anime. Most of them aren't paying much attention to the GUI - you don't see the MC using it often and they are often quite rudimentary.

The Soundtracks suit the setting very well too. I also liked the OP and ED. Don't know much more to say here though.

The characters beside the MC are mainly girls admiring him - exactly like woud want them to be in your dream. Nothing deep to find here too.
This may be a point of criticism though. The backgrounds and behaviour of the characters could be more detailed.

Enjoyment: This is what the whole anime is about. You are getting invited to Ichirou's dream and as your host he really wants to make this show comfortable and enjoyable for you. He is a really good host. You can enjoy cute girls, a completely OP main character, fancy art, a well fitting Soundtrack and those beautiful GUI.

Summary:
A very well-made happy-go-lucky fantasy RPG anime with a plain story, plain characters and an overpowered MC. Offers no deepness but may be the perfekt show for you if you like Isekais and just want to relax and dream a bit.
