Based on the given query, I will create a color palette inspired by the characters from “マイ・バレンタイン” (Mai Valentine) and “マリク・イシュタル” (Marik Ishtar) from the Yu-Gi-Oh! series. This palette will reflect the contrasting personalities and aesthetics of these two characters, incorporating colors that evoke their unique traits.
