series' main character is also based on the previous series' protagonist, who is a girl. Hoshino changed some of his characteristics to make him look more masculine. Hoshino says that she does not know where Allen's concept came from, since she likes her main characters to be rambunctious, rude idiots. Nevertheless, the character started behaving more informally across the series. In addition, Lavi was meant to be the protagonist of one of her planned series, Book-man. Other characters such as The Millennium Earl, Lenalee Lee and Komui Lee are based on real people, although Hoshino has not confirmed who they are. She has mentioned that some of them are famous scientists, while Komui is based on her boss. The character of Yu Kanda, based on a samurai, was created to vary D.Gray-mans Western setting. Hoshino found the design of some characters difficult early in the series. This resulted in Kanda having few appearances in the early volumes until the Noah's ark story arc, where he returned to join the cast with Allen having become harder to draw than him. On the other hand, she found the Millennium Earl and Reever Willingham easier to draw. When designing the characters, Hoshino first imagines their lives even though some parts might not be featured in the story. Their personalities are then written down along with their habits or eating preferences. She has admitted she does not have written details about a number of D.Gray-man characters. Hoshino chose the title "D.Gray-man" for its multiple meanings, most referring to the state of Allen and the other main characters. The Akumas were inspired by 1973 film, The Exorcist which Hoshino admitted scared her when watching it. In Timcanpy's case, his design is based on the silver accessory brand Timcanpi. The character Bak Chan was created with the help of Kaya Kizaki, who wrote the D.Gray-man Reverse novels. Hoshino has revealed that she got most of her ideas for the series while asleep in the bath for six hours. In designing the Black Order exorcist, Hoshino feels that their first uniforms were easy to draw so she like them. The second uniforms were brought the artist problems due to the idea of giving each the clothing zippers. For the third uniforms, the color remained black but Hoshino decided to them red too as a reference to blood because she thought such grotesque looks would fit the themes
