Game Reviews

When it was released back in 2008, The Devil on G-String was a massive success in Japan. It took forever (seven years actually) for the game to make its way over to the West and now people can get in on this and see why it was so successful. One very strange thing about this game is that it was released on STEAM, but for some reason, if you want the voice acting in the game, you have to pay nearly double the asking price!

The Son Of A Boss

If you are coming into The Devil on G-String thinking this is a cute and sexy kind of visual novel game you are in for a bit of a shock. This is a story that plays it 100 percent serious and I have to say that the story is quite excellent and the most appealing aspect of this game. I will also say that the less you know about the story going in the more you are going to get out of it.

Still, I will let you know the basics of the tale that is being told here. The main protagonist is a high-school student called, Kyousuke and he seems like a normal dude. However, he is actually the son of a mob boss and he is heavily in debt and can be very ruthless. Things take a twist when a new girl moves to his school and asks if he knows someone called Mao.

The Four Tops

Going into The Devil on G-String I had heard just how story-driven the game was. So, I assumed that it would be a visual novel that offered very little in the way of choice to the player. Well, you know what happens when you assume something? You make an ass out of you and me!

You see, this game offers far more choices than you would think and there are four routes that the story can take. Each one is interesting so in that regard, you will probably want to play through the game at least twice. However, I ended up wanting to see all four, and I was not disappointed in any of them.

An Anime By Any Other Name…

The presentation of this game is not going to blow you away. Do not get me wrong, The Devil on G-String is a decent looking game, it just has that anime look which I feel like I have seen a million times before. The characters look good, but are in all honesty, rather unremarkable. Still, the game is decent enough in terms of the visuals so I do not see you being turned off in any way.

One thing that is very surprising and unique about the game is the sound. I went in thinking it would be one thing and then being very surprised. The main character has a real love for classical music and this is reflected in the score of the game and it fits very well. The game offers full Japanese voice acting and it is great, but if you are purchasing the STEAM version, I am not sure you will be wanting to pay the extra price for it as the story is strong enough without it.


I had a great time with The Devil on G-String. So much, that I made sure a good friend of mine who loves visual novels played it so I had someone to discuss it with. It tells a fantastic story and it is a story that I feel more than warrants repeat playthroughs so you can see it in all its glory.


  • I loved the story
  • It is a very serious story that grips you from the start
  • Each chapter feels unique
  • I loved the music in the game
  • It has multiple paths for you to experience


  • Why does the voice acting version cost so much on STEAM?
  • The visuals are rather uninspired

G-senjou no Maou or if you prefer The Devil on G-String is one of the most interesting visual novel games I have ever played. Unlike many other visual novel style games. G-senjou no Maou/ The Devil on G-String is not just all about very graphic sex. However, this is still most certainly an adult kind of game and a game that is very intelligent in its story.

Rise Of A Boss!

The most compelling aspect of G-senjou no Maou/ The Devil on G-String is the story. The game has you playing the role of Azai Kyousuke who is the adopted son of a Yakuza mob boss! He is a high school student who is trying to balance his high school life with his underground gangster activities. Azai is a very, very compelling protagonist in that he is not good or bad or even what you would refer to as an anti-hero. He is a character with some real depth and your take on him will probably be different to mine.

The main story of the game is him trying to pay back a debt to his father. I really, really wish I could tell you more. However, this is a story that is so strong that you owe it to yourself to experience it without any of the major plot twists being spoiled. Part of what I really liked about the story here is the way it unfolded. It moved at the perfect pace; pacing is something many visual novels struggle with.

It Is All About The Characters

While I think that Azai is a fantastic protagonist. G-senjou no Maou/ The Devil on G-String has some other very memorable characters too. Your buddy, Aizawa is a bit of a dirtbag, but he is very well written. As you would expect, girls are aplenty here, but they are more than just eye candy and characters for the males to have their way with. The main female character, Usami is awesome! She is smart, geeky, socially awkward and also very deep. I found her one of the most intriguing characters I had come across in a visual novel game for quite some time.

Know What You Are Getting

As is the case with all other visual novel style games. You probably know what to expect from the actual gameplay that is on offer here. You mainly read the story, but you do have a few decisions that can move the story in a particular direction. The visual style is truly remarkable and the game has a very high-quality look to it. Which along with the excellent voice acting do move the story along very well.

I think that G-senjou no Maou/ The Devil on G-String is a great game and one that did grab me. It is the kind of game that I played through and then bugged some of my friends to do so. I did this so I had someone to discuss it with as the story was so impactful for me. I cannot recommend this one highly enough if you like visual novels!

Final Score 9/10


  • The story is truly great
  • I like how grey the main protagonist is
  • Plenty of interesting characters
  • The “hot” girls have a lot of depth to them
  • The pacing of the story is perfect


  • A bit more animation would have been great
  • You will want to talk to everyone about this!
