Thermae Romae

A Roman architects designs go unnoticed.

Lucius's ideas and designs have caught the eye of Emperor Hadrian.

Rome bathhouse architect Lucius Modestus is having trouble coming up with ideas for his future designs; after losing his job for refusing to adapt to the current times, he stumbles upon a time-traveling drain.

Marcus goes to see Lucius and finds him in a deep depression. A trip through a cauldron to Japan snaps him out of it, but not in the way he expected. Emperor Hadrian orders Lucius to build a new public bathhouse. While reflecting on it's design, he winds up in a Japanese water park.

Lucius slips on a wet rock and winds up in a hot spring village in Japan.

Lucius is a Roman architect whose designs aren't appreciated; he couldn't begin to imagine the strange adventure that awaits him.
