"Chaos," a black fog that consumes planets, distorting their environment and lifeforms. The beginning, or the end, of every story. [The Blue Pot], a Chaos located on Earth, the birthplace of humanity. There have been reports of unidentifiable creatures being discovered. And for some reason, a strange phenomenon that couldn't—no, shouldn't—be happening to the Captain is occurring. ▶ A World Drenched in Darkness, A Story Etched in Memory Dive into a vast and haunting dark fantasy narrative! Crushing stress, collapsing agents... and yet, the mission continues.

Unique cards, branching choices, and evolving "Save Data" shaped by your journey through the Chaos. Every run is unique. Build your own strategy and master the ever-changing battlefield. ▶ Characters That Dazzle the Eyes and Steal the Heart Gorgeous 2D illustrations and striking animations make every moment a visual delight! Fully voiced by top-tier voice actors, each scene draws you deeper into the story.

I have played lots of rpgs and I haven’t encountered any that have absorbed me this much as this game. Everything about this game is fantastic. The music, the graphics, the game play the art style. All are phenomenal! Well done

Great mechanics but over sized waifu designs

I love the rogue like aspect of the game, especially the itemisation and personalised deck building mechanics. Nevertheless, it’s extremely waifu oriented with over sized boobs bouncing around, which feels off and not necessary. Honestly nowadays would be nice to see more variety. In this aspect Rev1999 does way better. I hope this game will retain the FTP friendliness and the characters’ design will be more original and diverse. Good luck.

The game is great, interesting gameplay loop. A shame the women in the game have such humongous breasts it takes away from the immersion sometimes. I almost missed out on this games solid gameplay because I thought it was fan service slop. The world is interesting, the story is a bit bland and character designs are great if you can get past the fan service additions on their chests.

Less fan-service

Games great and all, but there should be less fan-service. Most girls here all have humongous breasts and it’s not the best to look at. I get it’s probably a marketing strategy to get people to spend more, but there should be an equal amount of females that are less revealing for us type of players.
