Classic Japanese x Doomsday Demon x Card RPG "Back to the Blue Sky"
This is your birthright mission - to lead the immortal young girl knights and transform into the "Devil King" to fight against the gods.

In the troubled times when gods and humans compete for planetary hegemony, humans have begun the "ninth orbit of human history" after being on the verge of extinction for the eighth time.
At this moment, the gods once again launched the "Orbit Correction Plan" in an attempt to completely erase human existence from the long river of history.
And you will lead the knights of the first eight orbits to fight against the gods and take back the blue sky.
——Even as the "Demon King".

▼Charming characters with distinctive personalities
From the glorious warrior born in the first track "Sword Edge", to the mysterious witch in the second track "Thousand Purples", to the energetic boy in the eighth track "Zero Shooting Orange", meet all kinds of "knights" here and weave your own bonds!
But please note - all are named "Demon King".

▼Refreshing and noisy combat experience
Brilliant text effects, exquisite Q-version character animations, and lively and noisy voice performances create the ultimate battle feast.
Let's shout out the name of your special move and punch hard!

▼Fun-filled base management
The last fortress of mankind, "Garden" - a mysterious base floating in the blue sky, where you can run a ramen shop, clean the library, study human history...everyday life outside of battle is waiting to be explored!
Isn't this the kind of fire that preserves human civilization?

▼Leng Che's unique world view
Like the whispers of looking up at the blue sky at the end of midsummer, the artistic style of wrapping the fiery core with a cold appearance runs through the whole picture.
The gray apocalypse is certainly charming, but please don't miss this melancholy blue poem.

▼Unabashedly hidden settings
There is an unimaginably huge world view buried in the game, but there is no need to deliberately memorize it. Let yourself be immersed in the torrent of information and devote yourself to the charming plot and ionate battles!
You can check the "Term Dictionary" and "Setting Database" at any time in the game. I wish you a happy game!
