Ґілберт Буґенвілія

Gilbert Bougainvillea is a character in the Violet Evergarden series. He is a major in the Leidenschaftlich army who values Violet more than anything, seeing her as a human being rather than a tool.

Violet was "given" to Gilbert as a gift to commemorate his promotion, having being promoted to a major in light of his wartime achievements and expectations from his bloodline. Dietfried, not wanting to take care of Violet, pushed this task to his younger brother. Gilbert then decided to enlist her on a militant unit that he had been appointed to take overall command of in his promotion to major. He later received permission to conduct private experiments at the training grounds as to whether Violet could be officially classified as a "weapon."
