Lucius is summoned by Emperor Hadrian, and he became so nervous that he finds himself with a strong urge to use the toilet, however he has to bear it. The Emperor asks him to build a bath in his Villa as long as he needs to have a private space to think about the Roman incursion in Jerusalem Bar Kokhba revolt. Some moments later he is sent once again to modern Japan, this time in a toilet-showroom, where he sees sea life footage from a digital TV (which he interprets as an aquarium) and a modern bidet toilet. He then uses this knowledge to create these for the Emperor who become impressed for his work and asks him to go with Jerusalem with him.
