The Rokudo Rounds volume 2

The preliminary round of the Rokudo Tournament, the Worm Crushing Hell, has begun. The rules are simple: Whoever defeats the most foes will make through the gruesome life-or-death battle. Out of the 30,000 participants, only the top 10% will qualify to move on to the main event, so it's time for En to show off what he's learned these past two years. However, a man named Zeku is in the ring, and he's commanding the crowd's attention with the insane number of kills he's racked up. He's even murdered one of the previous champions! Fixated only on the strong, Zeku sneers at the participants' dreams as he cruelly slaughters them. This spurs En to challenge him to a death match!
