This website features the Terra series, a collection of fanfiction centered on Shadow × Knuckles.
What is Terra?
Terra is a mythological story world in which the souls of Shadow and Knuckles resonate with one another and become part of a myth.
While its structure resembles the original Sonic universe, different chains of cause and effect overlap and intertwine, giving rise to a mythology of its own.
Story Structure
The TERRA series is divided into the following parts.
◆ Terra — Main Story
The story that serves as the starting point of the series. A 40-chapter Shadknux novel with a mythological structure, ultimately ending with Shadow and Knuckles realizing that their feelings are mutual and reaching a happy ending.
◆ Terra — After Stories
Stories that take place after the events of the Main Story.
◆ Terra — Reincarnation Stories
Shadknux stories in which Shadow, Knuckles, and Sonic—who share the same souls as their counterparts in the TERRA Main Story—are repeatedly reincarnated into different worlds. The structure follows a recurring cycle: Shadow and Knuckles realize their feelings are mutual → happy ending → after some time, they are reincarnated into the next world.
◆ Terra — IF Stories
Short stories and side stories with looser settings.
Relationships
◆ Romantic Relationships

Why “Mythology”?
In Terra, the relationship between Shadow and Knuckles is portrayed as an inevitability that repeats itself—destiny becoming myth.
Even if it could only exist within the imagined world of fanfiction, I wanted to read a story in which Knuckles saves Shadow’s lonely soul, and an epic story in which everything revolves around Knuckles.
That eventually ledｚ me to one simple conclusion:
“Then why not create a Shadknux mythology?”
And that is how the Terra series came to be.
Sexuality and the Body in Terra
Terra is strongly influenced by the Kojiki, Japan’s oldest surviving collection of myths.
In the Kojiki, sexuality and the body are closely intertwined with the creation of life and the land, as well as with deeply human qualities. The gods are sacred beings, yet they are strangely human—and at times even vulgar. Sexuality itself is not inherently treated as sinful or shameful.
Like the Kojiki, Terra presents sexual desire, romance, the body, motherhood, and every aspect of human nature as coexisting with sacredness within a single world.
For this reason, sexual themes in Terra are not portrayed as corruption, impurity, or something opposed to sacredness. With sexuality understood as something akin to life itself, it is treated simply as one of the natural aspects possessed by the characters who inhabit this mythological world.
