Battle of the Black Dragon Gate (5)

Inside a metallic room familiar to Shye, two magic circles glowed—one blue, one purple—illuminating the surroundings.

Meanwhile, near the glowing arcane circles, Sanada sat in his room, watching everything unfold from Shye's perspective through the system on a small, blue holographic screen.

He was torn between whether to help and risk himself again. Sanada, too, had a wish, just like the sinister snake. 

He wanted to return to his old world, even if only to die there.

Perhaps see where his beloved mother was buried and visit her grave.

After all, she should be dead by now, tragically unable to see his son once more before she departed the world she was living in for eternity.

Sanada had been trying to return to his world for decades, and only now, after a flash of inspiration from the ongoing war, did he manage to finally complete the portal that would allow him to return, though he was not sure where on earth it would take him.
