ABOUT THE GAME
Allocate work,
Collect misfortune.
``How to Create a Devil's Heart'' is a company management simulation in which you send lower-rank angels to the human world, entrust them with evil tasks, and collect unhappiness energy. Create a devil's heart by the deadline by allocating work and redrawing abilities through reincarnation.
WORK RESULT
Compare abilities and work,
Achieve great success.
We compare the intellect, spiritual strength, power, and work conditions of lower-class angels, check their success rate, and send them out to work. You can earn funds and misfortune energy depending on the results.

Allocate work based on ability and conditions
Lower angels have intelligence, spiritual strength, and power, and the skills and success rate required for work are also displayed. We determine compatibility, send them out to work, and collect their unhappiness energy.
Redraw abilities with reincarnation gun
Lower-class angels who are not suited for work can be reincarnated with the reincarnation gun and their abilities can be redrawn. The rule that treats the re-drawing of personnel as reincarnation connects company management and the world of the work.
The story overlaps with the management with a deadline.
We aim to achieve our goals within the remaining days by moving forward with our work in the morning and afternoon. At operational milestones, conversations between the angel Emmanuel and the demon Nina advance the story.
