In this episode, Senku and Kohaku find a hot spring so that Kohaku can take the water to her sick sister, Ruri. Senku is thrown off at first because he believes that she confessed her undying love for him. She denies that she loves him, but confirms she likes his way of life. However, I do think she will fall for him eventually, but she is more concerned about her sister’s health right now.
The jug with the hot spring water in it is too heavy and Senku offers to carry it. He eventually falls over and decides to create a vehicle to help them transport the supplies. Kohaku believes the hot spring has healing properties. Senku knows it will not heal her sister, adding to the primitive origin. They arrive at Kohaku’s village where two guards will not let Senku in because he is an outsider.
Where Two Million Years Have Gone
Senku is excited about finding the village and wonders where all of these people came from. He deduces that they were born post petrification due to their primitive nature and assumes he will be able to take over the village.
He encounters two guards that will not let him pass. So he tests their intelligence by creating bubbles. They don’t know what the bubbles are an immediately take a defensive stance and scream for Chrome, their village sorcerer.
Science vs. Sorcery
Chrome arrives on the scene and explains away the bubbles while popping them. This surprises Senku and he is excited that another person interested in how the world works is alive.
Chrome tries to amaze Senku by using crystals to create various colors of fire, but Senku can deduce how he achieved the fire. Seeing Chrome’s passion for sorcery makes Senku think of Shishio.
He tells Chrome that Shishio would eventually try to kill him because he too is interested in how the world works and even though he doesn’t understand everything, his existence and abilities would challenge Shishio’s purified world.
Chrome challenges Senku to a battle of numbers and puts up his entire lab as collateral. Whoever wins takes it all. Senku crushes Chrome easily and takes his lab for his own, but invites Chrome and the two guards to join him and Kohaku in the Kingdom of Science.
Kinro, one of the guards is settled in his ways and tells Senku that he can not come into the villages because “rules are rules”. Kinro does ease up after Senku puts a gold coating over his spear.
While looking through the resources he gained from Chromes inventory, Senku gives shouts out to Dragon Quest and Monster Hunter.
Kohaku heads into town to see her sister, Ruri. Ruri turns out to be the priestess of the town and she is sick. Kohaku and Chrome are trying hard to figure out what can save her.
Senku decides to tell Chrome what happened to the world with petrification over 3700 years. Chrome is overcome with grief and hope and vows to help Senku rebuild.
Senku says he can save Ruri with an antibiotic.
