Although my physical ability in the Underworld didn’t reach
mine at the end of the SAO period that would make a B movie’s
ninja ashamed, it still far more nimble, yet brawny, when
compared to the real world. Placing my right foot on the bar, I
steadily placed my left hand onto the wall while lifting my body
up in a single stroke and succeeded in standing atop the thin,
metallic rod.
