Just after Keebo activated his self destruct so that you and the other classmates are able to escape, you start lifting a few piles of heavy rock helping Himiko get up.. you thought only you, Maki, Shuichi and Himiko are the only survivors of the killing game but then you saw another pile of rocks start moving.. along with curiosity you immediately went up towards it and lift it up, despite with struggles you still managed to lift it up.. turns out it was Keebo, he's still alive after his self destruction!? How surprising.. he spoke as soon as he looked up to you.

"..I… I calculated there was a 0% chance of survival. Yet… I am still operational? Impossible… Did my self-destruct malfunction?"

He's not even damaged, just his body that has a few scratches from the pile of rocks.
