Summary

Over the next year, Minami creates a photo journal of the Kingdom of Science's progress while building the Perseus. They celebrate holidays such as valentines, play winter sports, Ukyo begins teaching at the science academy, lathes are made, silkworms are found, and progress on the Perseus happens steadily.

By the end, Minami prepares to take a picture of everyone with the completed ship, while shedding tears that it may their last. Senku tells her that he is positive they'll solve the mystery of the petrification.

Minami cracks a smile, as she tells everyone to gather for a picture and laments that she isn't in it. However, Francois predicted this situation and had a camera timer made so she could join them all.
