Alright then keep your secrets
The Hidden Dungeon Only I Can Enter is not an isekai, but it sure does feel like one. It follows Noir, a baronet (the lowest noble class), who only has one skill. It’s called Great Sage, and let’s him ask the spirit of a sage who knows almost anything, but it gives him crippling headaches. Never fear though, it turns out kissing helps alleviate his headache (you can see where this show is going). trying to improve himself, he asks the sage for a nearby dungeon. The sage directs him with the password to enter it. There he meets a woman adventurer who long ago got trapped in chains and kept alive and unconscious, but able to talk telepathically. She grants him her skills, which allow him to create, edit or delete his own or anyone else’s skills. Using them comes at a cost though, they require life points. How does one get more life points? Well eating good food, spending money, or the show’s favorite option, doing “romantic” things with women. As you might expect, this means the show ends up having lots of fan service, panty shots, boobs rubbing against him, oh and face sitting for good measure. Of course these all happen in the name of slaying monsters and removing curses, but the show spends a lot more time on the gaining of LP than any actual quest.
At best, I’d call this a poor man’s 8th son are you kidding me?. The setup is similar, lowly person gets OP powers, gets a harem, does quests. The difference, however, is that 8th Son at least tried to do some political subplots and played with the tiered system. Hidden Dungeon mentions this and has higher nobles be rude to Noir a bit but otherwise its a non-factor (at least thus far). Instead we get low stakes dungeon exploration and lots of anime boobs. Hell, the show even goes to a “Harem Pride” event to try and earn money and LP. This turns into a bunch of masked incels heckling women about their appearance. Our parties women are so cute and so nice though that they when the crowd over with their performance and fawning over Noir. This is an ENTIRE episode, and of course this causes some of the girls to like him even more. Oh and this doesn’t even address that his little sister is a little tooo into him and the rival receptionist literally has a grade A in face sitting. So yeah, this show goes a bit too hard into the fan service and the overall plot and characters suffer for it. It still gets a star though because there’s a Lion named Tiggerun and he’s pretty chill.
Is it trash? YES
