Kuchiba

Kuchiba is a former security officer in Planarcadia who worked with the Department of Aberration Defense and the Interastral Peace Corporation. In truth, Kuchiba is an ancient descendant of the Leviathans, and during the events of Good Hunting, she quit her job as security officer and left to travel the cosmos. She enjoys food and frequently posted restaurant reviews in her free time, leaving her vault of review notes for Sparxie when she left. Upon the arrival of the Astral Express to Planarcadia, Kuchiba was able to track them down after they were led astray by Sparkle. She introduced herself and her role to them before escorting them to Graphia Academy on request. Along with Ashveil, she was called in to investigate the murder of Lyndon Skott and the key members of Synwish Syndicate such as their boss Polwave and their second-in-command Caustide. While Ashveil suspected that the victims' autopsy implies that the killer is the infamous Herald of Death, Kuchiba informed him that the Herald of Death was executed five years ago. Kuchiba and Ashveil continued their investigation, with Kuchiba suspecting Fulwish, the director of the Research Society of Happy Smiles, due to her possible connection to the case. Ashveil noted that only a select few such as Security Bureau investigators, members of the Department of Aberration Defense, and those involved in the Herald of Death case could replicate the precise killing method. As Ashveil and Kuchiba attempted to infiltrate the Research Society of Happy Smiles to confront Fulwish, they were met by a crowd of people who had undergone "Happiness Surgery," all behaving strangely. When they finally confronted Fulwish, she offered no satisfactory response to their accusations, and the duo ultimately left the gathering without answers. She later joined Ashveil and the Astral Express Crew in confronting the Daybreak Squadron at Star Rail FEST and within the Torn Scroll.
