Giant Factory

Giant Factory also known as "Gift of the King Goliath" is a sacred gear appearing in DxD Black Lamb and Heavenly Dragon King's Rebirth. It is a powerful creation-type sacred gear that is first revealed in Life 2 and is owned by Tatsumi of classroom 4-C. Julia, the descendant of Caesar the Great and a bishop in Diehauser Belial's peerage is also in possession of this sacred gear in Heavenly Dragon King's Rebirth.

Summary
First used during the Royale Day fight by Tatsumi and Celina against the four first year students on Rebecca Phenex's team. Tatsumi used it to create a "small" giant that was capable of defeating one and intimidating the other three. Tatsumi later brags that this was one of his low-tier giants and that if he put serious thought into it he could've created much stronger giants.

When Julia reveals herself as the only sacred gear user in Diehauser's peerage she demonstrates to the Student Council her abilities by creating a flaming giant that was able to destroy three trees with one punch. She then states that because of her decades of training she could create giants out of any property she wanted.

Appearance
Giant Factory initial form is that of a long light red scarf that manifests around the wielder's neck. In order to prevent it from being exploited during the Royale Game, Tatsumi uses magic to hide it's appearance, making it blend in with his regular gym clothes.

Abilities
Giant Factory ability is the ability to create giants out of any element or property the wielder can think of. Being able to create a giant out of flames, wood, earth, steel, flesh, or even demonic/light energy with the wielder being limited by their own imagination or strength. Because of the power this sacred gear eats up, the wielder is only capable of making 2-3 giants at a time. The giants creation works by manifesting as the element the wielder wants (a giant flame, a large sheet of metal, or a tree) but then will shape and grow into the giant the wielder is thinking of.

Drawbacks
The wielder is limited
