"TK" is a mysterious character who speaks in nonsensical English phrases depending on the situation of the scene, though he does not know English fluently. He saves the team many times and does know some Japanese but rarely speaks it, and it seems he understands what the other say to him. He is talented in almost anything (mostly in dancing). He was always seen dancing even though fighting his enemies. His real identity and his name are still unknown even to the SSS, so they identify him as "TK", a nickname he gave himself.
One particular trait of his is his inability to remain still, as he is in constant movement whenever he is not doing anything at all (although at times he can be seen not in constant movement).
