Time Kyoshitsu: Tondera House no Daibouken

A boy named Justin Casey searches for his friends Angela and Corkey Roberts during a game of hide and seek when a sudden storm forces them to seek shelter in a house they had not noticed before in the wooded area. Inside, they find a robot named Solar Ion Robot (SIR) and meet the house's owner, Professor Humphrey Bumble, who shows them his time machine. Attempting to power the machine using a kite during the storm causes SIR to briefly change personality and send the house traveling through time. Due to errors in the time travel process, the children remain unaware of how long it will take to return home. During their journey, they observe and take part in various events from the New Testament, ranging from the birth of John the Baptist to the emergence of the Apostle Paul, with minimal consequences for their actions.
