The Spread Shot of Eternity Larva from the world where the four seasons are in total disarray (a Touhou LW original). An eternal larva that has gotten too close to becoming a god attacks. Fairies are eternally young. The reason for that is that nature itself is constantly being reborn. Mother Nature produces offspring, raises them, ages, and fades away, all while remaining forever young.

The Focus Shot of Eternity Larva from the world where the four seasons are in total disarray (a Touhou LW original). An eternal imago that has gotten too close to becoming a god attacks. With the existence of fairies in Hell, it's clear that death and rebirth are a part of nature. All things are in a state of flux, as is existence itself. This unending process of change requires energy, without which everything would stagnate. Just as with the far side of the moon and people of Hourai, without death, there is no life. Death is salvation.

A Spell Card of Eternity Larva from the world where the four seasons are in total disarray. She spreads swallowtail butterfly scales in this attack. Swallowtail butterflies love eating the leaves of tachibana trees―evergreen fruit trees that exude fragrance throughout the year and are considered symbols of immortality. It's thought that the Japanese term "tokijiku no kagu no konomi" (roughly "fruit of immortality") refers to tachibana oranges, and it's said that Tajimamori, who was sent to Tokoyo no Kuni, an ideal land beyond the sea, brought tachibana oranges back from his journey.

A Spell Card of Eternity Larva from the world where the four seasons are in total disarray. She flaps her wings leisurely in the summer sky. Swallowtail butterfly larvae resemble silkworms, and it is possible that they were seen as a kind of dichotomy. Silkworms produce silk thread as they pupate, giving them a fleeting productivity window. In contrast, what swallowtail butterfly larvae lack in productivity, they make up for with the promise of a future where they will flutter beautifully through the sky. It's said that the production of silk was once overseen by Hata no Kawakatsu.

The Last Word of Eternity Larva from the world where the four seasons are in total disarray (a Touhou LW original). A new god sets out to build a new world in this attack. In Japanese, Eternity Larva refers to herself as "yo," a term that's said to have been first used during the Heian era. From this, it's clear that the consciousness inhabiting her favors new things. However, that doesn't mean she gets swept up in trends. As in the Japanese saying "learn from the old to understand the new," she intends to create a new world based on knowledge of what already exists. "Eternal Night Worship" is a new religion that was also conceived of in that way. While those in power stand idle, the people continue to suffer. The consciousness within Eternity Larva simply wants to deliver the people happiness in the present, not the distant future.
