Apocalypse Zero Volume 6

Kakugo faces Bolt, a warrior protected by the Fortified Armor Shell Shin and the souls of four hundred warriors who died facing Kakugo in battle. Kakugo's Fortified Armor Shell Zero is still out of commission so Kakugo does what he must to win. He literally tears one of his Zero Form Iron Balls from his body and Faces Bolt, who stands between Kakugo and Garan Castle, the fortress of Kakugo's brother Harara, who plans to destroy and remake the world without humanity's sullying influence.
