A rainy day with a very special atmosphere, nature dominates. The sky is heavy and dark, the thick clouds almost seem to touch the ground. Rain patters incessantly on the lush vegetation and the Stone Age village. The trees, which normally seem strong and resilient, bend slightly under the weight of the water. The earth underfoot is muddy and every step leaves deep imprints.

The rhythmic drumming of the rain mixes with the quiet murmur of the rivers, which swell due to the rush of water. The smell of wet earth and freshly fallen rain hangs heavy in the air, mixed with the scent of damp leaves.

The villagers remain in their dwellings, while Senku and his group still engage in scientific projects, perhaps in a covered area or under improvised shelters. The sounds of the tools and experiments mix with the rain, and the calm yet focused mood that Senku exudes creates a contrast to the hectic nature around her. It is a moment of calm and reflection amidst the unstoppable natural world.
