Muguruma's 9th Division, Moves Out

Summary
The pendulum of time has swung forward nine years, and mysterious events are occurring in the outskirts of the Soul Society. Three shadowed figures watch on as citizens of Rukongai are devoured and killed by a strange white substance. Some time later, Shinji, Aizen, Mayuri, Hiyori and Urahara meet to discuss the recent disappearances of various Rukongai citizens. Kensei Muguruma and his ninth division are deployed to assess the situation, and happen upon a gigantic hollow, which attacks three boys. One of the boys, a younger Hisagi Shuuhei, is saved from certain death by Kensei, who obliterates the hollow with his released zanpakuto, Tachikaze. Later in Mayuri and Urahara's lab, Hiyori angrily reminds Mayuri of the fact that she is a lieutenant and he is only a 3rd seat, but he retorts that as long as they are in his lab, he is of a higher rank than her. We also get our first glimpse at a gigai, a prototype at this time, but still an idea that Kisuke had long ago. Hiyori is chosen to go from 12th squad to see what's going on with the recent disappearances of the citizens. Kensei and the rest of his squad are camping in the woods, waiting to see of any signs of whatever has been attacking people. Toudou, one of his subordinates, seemingly kills Tosen and the rest of the group, then gets struck down himself. Kensei, the only one left, is imprisoned in a well of darkness and then impaled with a blade. When the darkness lifts, he recognizes his attacker.
