Code: 04 of the Code Breakers. Toki's power revolves around magnetism, but later on he also exhibits the ability of mercury manipulation. When he loses his power, he takes the form of his younger self. He's the joker of the group, always fond of teasing people and has a propensity to tell outrageous lies (which fool no one but Sakura), but gets serious when it comes to his sister, Nenene's, safety.

He's extremely popular with females and has a strong liking for breasts. He follows the Hammurabi code variation of "an eye for an eye, a tooth for a tooth and the hammer of justice for the wicked."
