TS Ero Trap Dungeon

TS Ero Trap Dungeon


You have been defeated by the Demon Lord, magically transformed into a young girl, and dropped into the obscene underground labyrinth he built for fun. Whether you are able to break through and challenge the Demon Lord again or succumb to the dungeon and become his toy is up to the choices you make.

Writing: Mizuki Nanase (Pixiv)

Cover: Souzuki Naru (Pixiv)

You are a hero chosen by the spirits of light.

Having received blessing from the spirits of light, you gathered allies while traveling the vast world, sometimes helping the populace, and occasionally foiling the Demon Lord’s plans.

You challenged the Demon Lord with the experience you had accrued.

However, he was stronger than you had imagined, and even using all of your power and even the trump card you’d prepared in advance, you weren’t able to beat him.

Currently, you and your party are battling the Demon Lord, and are on the brink of defeat.

"Kukuku, your trump card, the magic of the light spirits, was too weak. Your recovery-magic using Priest and your offensive magic-using Magician have also been defeated, and all that’s left is you,

Hero, and the one-armed, shield-bearing Knight. Your situation is the very definition of despair, no? You have no options left anymore, do you?"

You’ve lost your trump card, your allies have been injured, and you can’t fight any longer.

"So, what will you do, Hero?"

You face the Demon Lord standing in your way...


1. "I’ll stand up to defeat you no matter how many times it takes!"
2. "Just kill us already..."
3. Silently grip your sword again and attack one last time.

while I enjoy everything about this game and can't recomend it enough...  There are game Braking glitches that prevent completion of it.  For example on C203 both options are unclickable.  In it's current state I would NOT download it.

It's got that japanese approach to porn, and is large enough that it takes a while to get to the new content. the idea is ambitious, even if the UI is a bit awkward.

Quality writing and fun interactions, it makes it quite easy to understand what has happened if you decide to do multiple playthrough thanks to its classic adventure book tick list on the side pannel.

Once this games content expends it will have so much replayablity, unlocking the different dialogs and paths based on effects and previously triggered events.

I was surprised by how much I enjoyed it. I was uncertain if I should try it out and glad I did. Feels very much like a choose your own adventure with a bunch a variables that can effect future choices. Yes, over all there is one path to go down, but in a Dungeon there always is.

I really love this game. The writing, the concept, and the kinks shown so far. It's right up my alley. 


However... It is so damn short! I'm fairly sure that I've run through every option in maybe 20 min. Please, keep working on it!
