Gilbert Bougainvillea (ギルベルト・ブーゲンビリア, Giruberuto Būgenbiria?) is a character in the Violet Evergarden series. He is a major in the Leidenschaftlich army and the only one who really valued Violet, seeing her as a human being rather than a tool, contrary to his brother Dietfried, who saw Violet merely as a weapon for war.
