Items and Weapons

There are several key items and weapons in the world of Uraboku.

Items
The cross necklaces, made by Yuki, act as a charm imbued with the power of the God of Light. It protects the wearer from fatal injuries as demonstrated when Tsukumo was gravely injured by Reiga, glowing softly in the aftermath of Tsukumo's ambush.

Since Yuki did not know Luka's birthstone, he embedded the powers of protection into the whole necklace, unlike the Zweilt's charm where the properties are sealed in the stone in the middle of the cross.

Later in the manga, when Kuroto and Senshiro joined the rest in Twilight Mansion, Yuki made them their charms.

Weapons
All of the Zweilt Guardians from the Giou Clan have their own designated weapon which is accompanied by the rings they wear. Luka Crosszeria has his own uniquely shaped sword which is summoned by activating one of the ear piercings on his left ear.
