Background
Nathan was the 5th generation head of Rosenthal Family, who continued the work of their ancestor and founder Obed, who was banished from his homeland as a heretic for developing a method of creating golems from corpses, ending up in the East. Their greatest desire was the creation of the perfect golem, one with a perfect soul and a perfect body - a god. The 4th generation head, Isaac, who was dedicated to this goal, held little hope for Nathan accomplishing it.

As part of the development of the Rosenthal style, Nathan created four artificial souls with greatly increased abilities; Taowu, Taotie, Hundun and Qiong Qi, capable of producing superhuman strength when their charm was attached to a corpse.

When Isaac was on his bed due to disease, before his soul could be lost due to, Nathan transferred it into the Taowu, imprinting it on its artificial soul. The Rosenthal style would continue to develop over the subsequent 19 generations but their ultimate goal of creating the perfect golem continued to elude them.

Abilities
Nathan made use of Rosenthal-style Necromancy, developed by his predecessor Isaac from combining the Kabbalistic method of creating golems by placing artificial souls into corpses devised by Obed, with elements of the Taoist Hopping Zombie Spell. As part of this, Nathan was capable of creating artificial souls, also referred to as false souls (偽りの魄), which are stored in charms with a sephira inscribed on them and inserted into corpses to animate them.

Nathan furthered the development of this style by creating four artificial souls with greatly increased abilities; Taowu (檮杌), Taotie (饕餮), Hundun (混沌) and Qiong Qi (窮奇). These four, sometimes referred to as Evil Spirits of Numbers (ナンバーズの悪霊), are capable of producing superhuman strength when their charm is attached to a corpse.

He was also capable of transferring souls to a certain extent, having transferred the dying Isaac's soul into the Taowu.
