黒筆

身披黑衣的少年。 带着“游历故事的世界，有扭曲便加以纠正”的使命，据说以前曾与白姫一同为此殉职。 用携带在矢立中的笔，修复绘草纸上缺失的文字。 有时也会如刀般挥舞斩杀敌人。 性格冷静沉着，对任何事都毫不畏惧。

摘自本作简介中该角色的段落

"Do you know what an Adabana is? It's a flower that blooms and withers without ever bearing fruit." A boy clad in black. He bears the duty of traveling through storybook realms and correcting distortions as he finds them, a task he used to do with Shirohime. He uses the brush he keeps in his brush case to restore lost text to illustrated books. He also occasionally uses his brush like a sword to cut down enemies. Calm and collected, nothing can faze him. [From ANIPLEX.EXE]
