Doleful is half-British, half-Japanese, and possesses a remarkably negative disposition. Since he was a child, Doleful has always had a remarkable penchant for attracting dangerous phenomenae that pose a threat to his well-being. This peculiar ability of his has been dubbed the 'Danger Magnet,' and is considered by many to be the mark of a great detective. In the past, Doleful had been treated as an angel of death, and as a result, he struggles to interact with others without second-guessing himself. However, though his life in constant danger, he always survives using his peculiar senses, an ability which comes in handy during particularly perilous investigations.
