The Real Gunvarrel Is Standing Right There
Kaito and Akiho travel to the Tokyo Expo with their robot, where they discover they have to share a hotel room. As Kaito has nightmares that night, Akiho asks him to be a bit more open with his troubles. Whilst preparing for the expo, Akiho becomes excited when she hears Misaki will be at the expo promoting the Exoskeleton robots. Kaito decides to meet up with her in person in order to confront her about Mizuka's death, also talking about Kimijima, her meeting with the real Airi, who woke up in hospital the other day, and above all, her attitude towards Akiho. The Tokyo Expo soon begins with Akiho having a tough time impressing the crowd with the recent bias against Gunvarrel. Despite Kaito's warnings, Akiho goes to see Misaki, who is seen in a fully robotic suit. Just then Sawada appears and brings out a gun, shooting it when Misaki starts to run away.
