Description
“The Hero defeated the Demon King in the war of men against demons…” Those kinds of stories are a thing of the past. Nowadays, adventurers, demons, Heroes, Demon Kings, and so on are all occupations that no longer involve putting one’s life on the line. Peace has returned to the world, and dungeon exploration has now become a form of entertainment. Adventurers and monsters now all fight using clones they’ve created with magic in an extremely popular form of dungeon clearing where nobody dies. The footage of the dungeon getting cleared gets broadcasted all across the continent, and I’m a member of a Hero’s party that was ranked the 4th most popular in the world… but not anymore. Parties had a limitation of 5 members, and I was told that an unpopular job like Black Sorcerer would only get in the way of getting to 3rd place or beyond. Now that I became unemployed, I was forced to find another party but I just couldn’t find one. One day, I encountered a beautiful blonde red-eyed woman who told me she had a job for me. After being so touched from having someone recognize my abilities far more than my past comrades, I ended up agreeing to take an interview without asking for the details. When I arrived at my destination, I was at the world’s hardest dungeon where no party has ever reached the final area, the Demon King Castle, where the Big Four and the Demon King were waiting for me. This is the story of a Black Sorcerer that was kicked out of a Hero’s party and joined the side of the Demon King Army to repel the Heroes.

My Thoughts on Welcome to the Impregnable Demon King Castle – The Black Sorcerer Is Offered a Seat as a Member of the Demon King Army’s Top Brass After Being Kicked out of the Hero’s Party Because They Didn’t Need Debuffs
First Impressions
Okay, that title is a mouthful! Honestly, I went into this expecting another run-of-the-mill "kicked out of the party" revenge story. And while there are elements of that, it seems to be trying to be something a bit different, a bit more… wholesome, even. The premise is that the MC gets the boot from his hero party because his debuff abilities aren't flashy enough for their entertainment-driven world. He then gets an offer from the Demon King's army. Intriguing, right?
What Works Well
What immediately grabbed me, and what a lot of readers seem to appreciate, is the world-building. The idea of dungeon crawling as a form of entertainment is a fresh take, and it sounds like the author has created a solid magic and combat system. The characters, for the most part, seem to be well-developed and likeable. I'm especially interested in the dynamic between the MC, Lem, and his hero best friend, Fenix. Their rivalry sounds engaging. Many readers praised the writing style, noting a good flow and enjoyable interactions between characters. There is a good amount of world building too.
Areas of Concern
One of the biggest criticisms I've seen revolves around the romance, or lack thereof. The MC is often described as incredibly dense, even to the point of frustration. Some readers feel that the female lead is practically throwing herself at him, and his obliviousness strains believability. Another issue that popped up is the pacing. Some felt that the story moved too slowly, with repetitive exposition dragging down the experience. Some readers felt the MC was too positive after experiencing abuse from his former party.

Final Verdict
Overall, "Welcome to the Impregnable Demon King Castle" seems like a decent read with a unique premise and likeable characters. However, the slow pacing, dense MC, and potential for repetitive exposition might turn some readers off. If you're looking for a light-hearted fantasy with a bit of slice-of-life and aren't too concerned about a fast-paced romance, this might be worth checking out. I'd recommend giving it a try and seeing if it clicks with you.
