Pseudo Soul

Pseudo Soul (擬似魂) is an item created by Rimuru based on the core mechanics of Sarion's homunculus. It was developed to be a vessel for the nucleic heart. Treyni and the rest of the Dryads, who have evolved into Dryas Doll Dryads, have their chaos cores housed within pseudo souls. They have not been mass produced by Tempest yet, making Rimuru the only known source for this item. In the anime, pseudo souls are depicted as yellow orbs
