Guenael Lee

A small old man wearing something like headphones on his head. His spiritual weapon is a small knife. He has a despicable and sadistic personality, enjoying inflicting pain on others unilaterally and is not loyal to his creator, Gremmy. He appeared in front of Yuin and Yachiru, who were treating Rose and Kensei at the Comprehensive Relief Station, and initially overwhelmed Yachiru with his abilities, but was eventually cornered by Yachiru's initial release and was "forgotten" and then annihilated by his creator, Gremmy. In fact, he is a figment of Gremmy's imagination and not a real person.
