He 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 others say to him. And 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, 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).

Otonashi wakes up in the afterlife to find out he has no memories of his life before death. Desperate to survive in a war that could yield another unfortunate fate, he joins the SSS in the battle against Angel, whose very mission is to destroy all inhabitants of this afterlife. As Otonashi struggles to recover his memory and learn more about this world, he finds that not all is as it had seemed.
