Widow
- Widow (ウィドーWidō?) Voiced by: Saeko Chiba (Japanese), Jamie Marchi (English)
- A woman who meets Kazuki after he gets beat up by a group of thugs. She is revealed to be a Communicator, and allows Kazuki to pilot her in order for him to retrieve Gio. She seems to have lost someone very dear to her, thus she partners with Kazuki because she feels that he has also lost someone who was very important to him. Though Kazuki treats her coldly, her only desire is to see to Kazuki's happiness. After the one-year time skip, she disappears once she reveals herself to be dying.[6]
- Like a spider, Widow can shoot fiber strands from her fingertips which can either ensnare targets or cut objects to pieces. She also has the ability to put someone to sleep with her nails.
