An ordinary man obtains an unreliable System. At first, all he can do is collect dark energy.
For now, he can only believe that right and wrong are decided in people's hearts, rather than judged by simple labels of darkness and light.
Using Space Beast cards in the name of darkness, he walks the path of justice in his heart.
A special card lets him combine two Ultras into one, but the transformation is interrupted. Darkness gathers in people's hearts, and a new darkness is born...
Only at the end of the road to redemption does he realize that the one who needed saving was not someone else, but his own heart!
Jun Himeya: I once thought he and I were nothing alike, but only at the very end did I learn that the haze in his heart was thicker than I could have imagined...
Ren Senju: He saved me and everyone on the plane. From that day on, he became my role model. I may have forgotten him once, but I'll never forget the sight of him walking away!
Gomon Ikki: He reminds me of a senior I once knew. I believe he's not a bad person!
