Kuroe Samejima is a supporting character in Grisaia: Phantom Trigger the Animation. She is a graduate of the Hollow training program, having been part of the same generation as Haruto Aoi. Her personality is marked by a quiet, clever, and subdued disposition, often categorized as a downer type due to her detached and low-key manner. Kuroe is defined above all by an intense and unwavering loyalty to her master, Enishi, and she shows little interest in pursuits outside of that devotion. In the narrative she operates as Enishi's personal bodyguard and secretary, using the capabilities she gained through Hollow to provide close protection and administrative support. Her most important relationship is with Enishi, for whom she acts with absolute dedication, though her shared background with Haruto Aoi also situates her within the wider network of elite operatives produced by the Hollow system. Kuroe’s development is not a central focus, but her steadfast commitment remains consistent throughout her appearances, reinforcing the theme of conditioned loyalty within the covert world she inhabits. Her notable abilities stem from her Hollow training, which can be assumed to include advanced combat proficiency, situational awareness, and the composure required for sensitive security work.
