45

Nana notices that Kuro is sick! Distraught, she rushes to Dr Go for help. He discovers that Kuro has been infected by a cyborg virus! Kotaro creates an antibody to help fight it, but he accidentally injects it into Hirosue, who ends up going on a rampage. Dr Go and Kotaro shrink down in an attempt to contain the antibody while Mi and Nana try to stop Hirosue while also taking care of Kuro. (Source: Wikipedia)
