Yellow Numbers

The Yellow Numbers ｢黄色軍団｢イエローナンバーズ｣, ierō nanbāzu｣ are a squad specialized in creating walls to ward off attacks. They are Tempest's main force and are comprised of the former two-thousand strong Orc elites of the Orbic army, clad in black full plate armor. Each individual is evaluated as A- rank.

Since they have a yellow aura about them, Rimuru decided to name them all, except the Orc Disaster's son, based on the color along with a number. Thus, the famous Yellow Numbers were born. Numbers assigned indiscriminately of gender, since there could be no gender inequality among fellow warriors. The Orcs have all evolved into High orcs. Though they possessed strength almost surpassing C+ rank, they were able to retain that level. All in all, they evolved into rather powerful warriors.^[1]

They were dispatched to every orc district as production workers. They quickly learned the appropriate skills from the dwarves and skilled Goblins. According to Kaijin, with time, they just might become as good as the Dwarf Manufacturing Battalion.

The Yellow Numbers aren't much on their own, but truly shine when together in a group. Geld is always out transporting goods.

During the Harvest Festival, the high orcs evolved as a herd. They all obtained the skills Steel Strength and Iron Wall. The officers under Geld obtained Earth Manipulation, allowing them to create a protective wall out of the earth. Moreover, they also obtained Full Body Armorize and inherited most of Rimuru's resistances, namely: Physical Attack, Pain, Corrosion, Electricity and Paralysis Resistance. They are also all equipped with Charys Shields ｢風渦楯鱗盾｢カリスシールド｣, karisu shīrudo｣, which provide them with anti-Magic qualities.

They would eventually be restructured ahead of the Nasca Namrium Ulmeria United Eastern Empire's invasion of the Great Jura Forest. Only the original 2,000 members remained as platoon leaders that commanded the Orange Numbers, the remaining members joined the Orange Numbers as superior officers to the newly enlisted high orcs.^[2] Together the Yellow and Orange Numbers formed the Second Corps commanded by Geld Junior. By the events of A Disturbance in the Royal Capital, the number of soldiers increased to 10,000 from the top soldiers of the Orange Numbers, with some soldiers reaching A rank.^[3]
