SinceSenku chose Magma as the third member of the exploration group, the other members of the Kingdom of Science are worried that Magma might try to attack Senku while they are down in the cave. However, Senku is only focused on the filaments. In Magma’s mind, he is thinking of attacking Senku because no one will be watching. Just as Magma is in thought, Asagiri Gen walks over to him and whispers instructions (it is inaudible for the viewer). says no one will be watching while they are in
Chrome is on high alert as the exploration group goes into the cave. When they arrive at the digging area there are pit traps. As Senku is explaining the dangers of falling into the pits, the ground starts to crumble. It seems like Magma tried to push Senku, but in reality, he tried to push him out of the way. Despite his efforts, both he and Senku fell into the pit.

The group made him an observatory. Senku was moved but thought about using it practically to keep an eye out for soldiers of the Kingdom of Might. Ishigami Village celebrated Senku’s birthday and the episode ends.
