An emergency alarm is heard across Seireitei, ordering all captains to gather at the First Division barracks for an emergency meeting. As Kisuke Urahara is awoken by the alarm, the announcer reports the Reiatsu of both Captain Kensei Muguruma and Lieutenant Mashiro Kuna have disappeared.

Worried, he, rushing to the lab, asks about Lieutenant Hiyori Sarugaki's location, only to be told she just left. As he rushes to the First Division, he regrets sending Hiyori to help the Ninth Division.
