Killa

Killa is a Killer Bee who crossed the Japanese border illegally in an attempt to exact revenge on Rachnera Arachnera, using Kimihito Kurusu as a proxy. Killa has the appearance of a young woman with short, light colored hair and large breasts. As a Killer Bee, she has four arms, with three fingers each, which are covered with a carapace. She also has carapace-covered legs and jaw. She has compound eyes, and her forehead has two antennae protruding from her forehead with what appears to be a trio of simple eyes between them. Most notably, from her back protrudes a large hornet abdomen with stinger, and two large insect wings. Her attire seems to consist of only a black top and shorts. Killa appears to be an extremely aggressive individual, becoming so furious upon being humiliated by a relatively harmless prank that she was forcibly deported from Japan and had her entire species classified as "dangerous". Due to her past with Rachnera, she becomes especially furious upon being confronted with Arachne thread. Kimihito, however, states that it was mostly her own fault that she got deported (which is arguably true, as she started the commotion, threatened other liminals who were waiting in line and provoked Rachnera into webbing her, and ended up exposing herself in front of everyone). She is highly determined when angry, and will stop at nothing to accomplish her goals, such as getting revenge on those who wronged her. However, when she is calm she can be reasoned with, as she apologized to Kimihito for endangering him to draw out Rachnera. Likewise, despite her aggressive and dangerous nature, Killa believes that, compared to herself, her fellow two illegal immigrants are truly dangerous and warns Kimihito about them.
