plot
the episode begins with Christopher presenting Houndbot to Professor Johnson as he explains that it can provide food and sleep and unlike other dogs Houndbot is incapable of fear as Professor Johnson gives Christopher and the team free tickets to Tokyo Japan to present Houndbot to Dr. Onodera as Steven falls asleep during jetlag and the scene changes to the Robotics Factory where Dr. Onodera soon meets the gang and Mystic One appears as he has a flashback involving the Mystic One and him as he claims that he ignored his warnings about the monster's curse as he tries cursing Dr. Onodera just as it gets sent to a large teriyaki pizza that Steven wakes up to eat much to Christopher's horror by exclaiming that Steven ate the cursed pizza and he wakes up sacredly asking if it really was cursed as Dr. Onodera comforts Steven saying that the chance of him becoming a monster is slim as the camera dramatically zooms in on Steven as the scene changes to Dr. Onodera's guesthouse where Steven is seen chained up to the bed as the scene changes to the city of Tokyo where some tourists are attacked by a 30 Foot Stevenzilla that uses Steven's famous catchphrase and knocks a tourist down as he records the whole event.

the scene then changes to the guesthouse where Steven wakes up and when Tracy offers him he declines as everyone gasps and Lt. Tanaka appears and says "let us hope Steven-san that your appetite was not satisfied last night" as everyone then looks at her as she apologizes for the intrusion and introduces herself as Lt. Keiko Tanaka from the Tokyo police as she tells the gang about the attack of the 30 Foot Monster that attacked the factory and downtown Tokyo last night as she thinks that Steven did it and when Christopher finds the chains bitten through by razor sharp teeth as Steven then thinks he was the monster that attacked the factory last night and Christopher tells Lt. Tanaka that Steven is innocent in all of the events with the monster as she gets a suspicion about him as the scene changes to the Noodle Shop where Steven is seen eating and Christopher explains that  Steven isn't a monster as he thinks there's a logical explanation for all of the current and past events happening in Tokyo as Tracy sees a giant footprint in the ground as the townspeople of Tokyo approach the team as the Lt. Tanaka returns with her force aiming to capture Steven as the gang runs from the police in pursuit to get away from them as the team arrive in front of a bullet train.

the gang climbs inside of the bullet train and tries coming up with a plan to escape from the police as they see Lt. Tanaka on the news as she climbs down from a rope ladder and she climbs inside and grabs Steven only to be thwarted by Tracy dropping her tray and slipping on it as Lt. Tanaka lets go of Steven as the scene changes to downtown Tokyo where the team tries hiding from the cops as Lt. Tanaka shows a picture of Steven to a local in downtown Tokyo as Eliot shows up with his parents and confronts him as he calls the police over to him as the Mystery Solvers run away from the police as Miyumi rescues them in time to disguise themselves as hoods and they at first are fooled by their disguises but Eliot points out their true identities to them as they give chase in pursuit of arresting Steven.

as Lt. Tanaka grabs Steven he says sayonara as the chase scene song plays in the background with the team and Miyumi split up into groups as the first group was chased by Lt. Tanaka through a sumo match with Christopher, Tracy, Houndbot, and Daniel watching the sumo match as Lt. Tanaka gets crushed by one of the sumo wrestlers in the ring as the four are seen running away from Lt. Tanaka as the scene changes to William, Stanford, and Steven running from the other cops as they serve tea with three peppers inside it burning their mouths as the cops run away and William, Stanford, and Steven laugh at them and the final scene changes to Tracy, Christopher, and Miyumi serving the police some food as they soon tie the cops up eat the food and run away as the song ends the Mystery Solvers crash into each other as Christopher asks if everyone's okay as Christopher says "that Tanaka doesn't give up we've got to get off the street before she finds us again" as everyone agrees to his plan as he calls Professor Johnson for help.
