A few days after the quake, a six-feet-tall frog waits for Katagiri to come home from work. Frog tells Katagiri that he is going to save Tokyo from an earthquake and needs his help. Katagiri learns that he can help by cheering for Frog as he battles with a Worm under the Tokyo Security Trust Bank, Katagiri's workplace. To prove his loyalty to Katagiri, Frog resolves a bank case for him; after this, Katagiri agrees to help Frog. They plan to meet on February 17 (the day before Worm will cause the earthquake) under the bank but on that day as Katagiri is returning to the bank from his rounds, he is "shot."
