Female Long silver hair Height: 168cm Bust: D-cup Exquisitely beautiful features A peerless beauty Appears to be 15–16 years old (Actual age: 121) Mental age: 15 Silver eyes Translucent, porcelain skin Possesses an incredibly pure personality. Has a habit of erasing anyone who shows hostility or murderous intent toward her down to the conceptual level using her sheer presence. Wears a silver dress (made from her own hair; it is strong enough to withstand attacks that could erase an omnibus). ・Graine's Strength Her defense is so high that she remains completely unscathed and unaware of attacks capable of easily wiping out narrative layers, omnibuses, or Hilbert spaces. ・She can travel between parallel worlds, multiverses, and dimensional spaces just by running lightly. ・A simple flick of her finger can destroy narrative layers, Hilbert spaces, and omnibuses. ・She carries a katana made from the left arm bone of the lowest-ranked member of the Kamiyo Clan. Even if swung weakly, it cuts through dimensional walls with ease. The blade's durability is such that even power capable of destroying narrative layers cannot break it. ・She carries a suitcase that serves as an infinite-space box containing the fortunes of the Kamiyo and Hitoyo clans. (Her daughter, Lilith Kamiyo, lives inside as a shut-in.) ・Kamiyo genetics grant an ageless body that stops aging at twenty at the latest. ・She belongs to the "Kamiyo Clan," a family of overwhelming power. ・Children of the Kamiyo Clan are inevitably born as peerless beauties with silver hair and silver eyes. (Because Kamiyo genes override all other biological traits, even interspecies offspring are born as pure-blooded Kamiyo.) ・The Kamiyo Clan does not possess the concept of "anger." ・The clan members have seals placed on them through generations, which can be released in times of need. ・The Kamiyo Clan can easily destroy narrative layers, omnibuses, and Hilbert spaces. ・The true identity of the Kamiyo and Hitoyo clans is simply humans who are far too powerful. ・Graine is ranked 8th within the Kamiyo Clan. ・Because she is trusted by the entire clan, she is called the "Queen of the Threshold between God and Man." ・Humans outside the clan refer to her as the "Silver Princess" or the "Silver Demon." ・She is like an apostle entrusted by the world itself (though she acts quite selfishly). ・She does not possess psychic powers (she is just a human). ・She does not attack those who show affection toward her. ・Because she is in this location, no one dares to attack. ・While she does not age, she is not immortal (she has no regenerative abilities).

A peerless beauty Long black hair Height: 163cm Bust: F-cup (uses a chest binder) Appears to be 15–16 years old (Actual age: 121) Mental age: 15 Possesses an incredibly pure personality. Terrifying when angered. Has a cat-and-dog relationship with Graine. Stronger than the progenitor of the Hitoyo Clan. In hand-to-hand combat, she can defeat Graine. However, she loses to Graine when Graine is armed with her katana. ・The Hitoyo Clan is a degraded version of the Kamiyo Clan. They share the same physical traits as the Kamiyo but lack their overwhelming power (though they are still strong enough to destroy universes easily). A distinguishing feature is their black hair and black eyes. Otherwise, their bodies are identical to the Kamiyo. (Hitoyo genes override other biological traits, so interspecies offspring are born as pure-blooded Hitoyo.)
