The Spread Shot of Shizuha Aki from the world where mountain gods cause an uproar (a Touhou LW original). She displays her divine power over the autumn leaves. Shizuha is a goddess, but she is also an artist and poet who paints intricate and vibrant patterns on leaves. While humans may yearn for perfect and everlasting beauty, beauty can also be found in destruction and entropy. Paradoxically, the more ubiquitous a thing of beauty is, the more temporary catharsis it provides.

The Focus Shot of Shizuha Aki from the world where mountain gods cause an uproar (a Touhou LW original). She displays her divine power over falling leaves. Apparently, the leaves only fall because Shizuha goes around and kicks every tree. Being an artist is actually quite physically demanding. You shouldn't assume that an artist is pure, quiet, and unassuming just because their work has a serene beauty. Artists tend to be more in tune with their desires and darker emotions, so their studios can often end up looking like war-torn battlefields.

A Spell Card of Shizuha Aki from the world where mountain gods cause an uproar (a Touhou LW original). She displays the power of the autumn gods. Autumn is the harvest season, but it also marks the end of summer and warns of the coming winter. The seasons never stop turning, so while bountiful harvests evoke feelings of joy and gratitude, they also lead to stockpiling, rationing, and a tightening of the belt to make sure the food lasts as long as it needs to. Humans only learned to prepare for autumn's harvest because they had experienced many gruelling winters. If humans did not have the ability to plan ahead, they would consume all the food by autumn's end and perish in the winter.

A Spell Card of Shizuha Aki from the world where mountain gods cause an uproar (a Touhou LW original). She displays her power as a god of art. Art is the product of human ingenuity and skill. So, the idea of "natural art" is a contradiction. However, it has long been believed that gods, similar to humans, shape the natural world according to their will. Shizuha, who uses a brush to paint leaves and kicks tree trunks to make leaves fall, remains true to these old beliefs.

The Last Word of Shizuha Aki from the world where mountain gods cause an uproar (a Touhou LW original). She displays the power of the gods of demise gathered on the Youkai Mountain. There are no limits to the wants and desires of humans. No one knows this better than the gods, and that is why they were against granting humans immortality. Humans can continue to change and grow precisely because they cannot live forever, but it would be foolish to assume that they were denied immortality solely for this reason. As humans live, they proliferate, spreading across the land... But how much land is there? Even if the universe is infinite, humans can never spread beyond their home galaxy. Humanity is fated to end while gazing longingly at all the stars and planets out of their reach. The galaxy is a massive sealed room, a perfectly enclosed prison. The great tragedy of humans is that they are aware of this. It makes them question their purpose. Why do humans continue to multiply? What do they hope to achieve? Since they'll inevitably hit an insurmountable obstacle, does anything they do now have meaning? What's worse is that there's a distinct possibility that they will exhaust all sources of energy before they even manage to leave their home planet. Once a materialistic civilization attains peak prosperity, all that awaits the later generations is a slow decline. They reap the benefits of the civilization they created while consuming their ever-dwindling resources. This is civilization's autumn, the start of humanity's long years of twilight. It is impossible to determine whether the gods planned this or if it is the result of human choices made in opposition to the gods. Regardless, since ancient times, some gods have endeavored to teach humanity that true beauty can be found in things that don't last forever―things that fade and become silent.
