"A Transient originally from the world of Gehenna, Ose is now active in Tokyo as a spy for the shadowy Agents, codenamed 057. He is an undisputed master of disguise, and can appear as a child or an adult at will depending on his mood. Even the most challenging of assignments pose little problem for him thanks to his exceptional natural talents, but this only leaves him bored and disinterested. He frequently attempts to seduce enemies well-disposed toward him, and sometimes takes unnecessary risks while on the job, likely in an attempt to bring more excitement to his work life."
