I Am a Swordsman in Tokyo

Traveling from the great era of spiritual energy recovery to Japan one year before the spiritual energy recovery, I became a sixteen-year-old high school student, Kazuki Kimura. He practiced cautiously, worked hard, and frugally prepared resources, hoping to leave all mankind behind after the spiritual energy was revived. But God played a malicious joke on him. A year later, the revival of spiritual energy... Did not come as expected.
