Due to the attempted assassination of Oyafune Monaka by SCHOOL, the security at the lab was disrupted. Some of its private guards were called in and some equipment was being transported. SCHOOL had planned for this and broke into it in an attempt to steal the Tweezers that were being kept there. ITEM figured out their plan and met them at the laboratory. Due to this, a battle between SCHOOL and ITEM ensued, and a large majority of the building was destroyed. Yobou Banka was killed during their battle.
