“Legend had it that in the deepest part of the oldest galaxy, there was a door as red as blood and fire.

Legends and myths, darkness and light, countless stories passed through this old door.

The Door of Constellation that overlooked everything would warn the sky and earth, sending darkness back to where it belonged.”

I wanted to be the hero but I knew in my bones that I couldn’t.

Ten years after the end of the world I struggled desperately to survive but I fell to my knees in the face of a great destiny.

“If only I were given one more chance.”

And like a miracle, another chance came.

It’s not like before, when I gave up and let go of everything.

I’ve had enough of playing the supporting role, now it’s time to rise above everyone else.

I’ll be the main character and reach for the stars.

Takahiro Nao, a 25-year-old drowning in debt and despair, lives only for his struggling family. Every sacrifice he makes is for them—until a selfless act costs him his life.

Armed with formidable powers yet haunted by his past failures, Nao steps into a dangerous realm of swords, magic, and ferocious monsters. Facing relentless enemies, harrowing trials of life and death, and an unyielding fate, he’s forced to confront the ultimate question: how far is he willing to go to protect the people he loves?Filled with emotional struggles, determination, unexpected humor, and a touch of romance, this story asks a powerful question to the readers: What would you sacrifice for the people you love?
