Putting the D in the double D.


An adventurer partners up with the demon queen in Hourglass & Pencil’s Mart and Tetra, an RPG available now on DLsite.

Mart and Tetra is a fantasy RPG following Tetra, a beginner adventurer who stumbles upon the forgotten remains of the Demon Queen Mart. Mart offers Tetra a deal: she will take over her body, use it to take revenge on the current demon king, and leave Tetra after she’s done. This will, in turn, make Tetra into a legendary hero, and improve her magical and physical abilities along the way.

Tetra agrees, but the arrangement isn’t as simple as it sounds. Mart needs magical energy to control Tetra’s body, and she only has enough of it to do so in short bursts. As such, Tetra has to do much of the heavy lifting. Controlling her, the player is tasked with exploring areas, speaking with human NPCs, and dealing with the weaker monsters. During the game’s turn-based battles, Tetra accumulates TP as she fights. If she accumulates enough TP, the player can turn her into Mart, gaining access to Mart’s overpowering might.

As she delves into dungeons and accomplishes quests, Tetra will be coerced into sex by various people, as well as assaulted by monsters. Part of the reason for Tetra giving into the abuse is to gather the magical energy needed for Mart, who, herself, will also engage in erotic actives, sometimes willingly giving herself to monsters for the fun of it. Certain erotic scenes will play out differently, depending on which character the player turned into at that time.

One day, me Tetra was walking in a dungeon.

I helped Mart, ex-Demon king by chance.

She took my body, so I was lost, but...

"I will make you Hero. Let's defeat the present Demon king with me!!"

I was so weak that I dreamed of becoming a hero.

I decided to take the proposition of ex-Demon king to defeat the Demon king.

Me, who can't fight but can save magic power, and ex-Demon king, who can fight but can't save magic power.

Will we be able to defeat the Demon king in the end?

Mart and Tetra is now available on DLsite for the promotional price of $10.90 (estimated from ¥1,144) until the 11th of March, at which point it will cost $13.61 (estimated from ¥1,430). A demo of the game can be downloaded from the store page.
