B: The Beginning

Koku uses a powerful uplift to reach the Moby Dick. He fights an insane Minatsuki who turns out to be an expiring Reggie whose memories were altered by the real Minatsuki – Laica, who sets a bomb on the airship. He escapes by helicopter with Yuna and returns to the hill where the fossils and inscription were discovered. Lily awakens in the hospital and realizes that Keith is pursuing Gilbert on his own. Gilbert tells Keith how he proposed and led the attack on the institute, gaining Minatsuki's confidence with a lie. Minatsuki was the original target of the attack, as he could stabilize all the Reggies and give them independence from the military and king. Believing that he is following prophecy, Laica stabs Yuna. (Source: Wikipedia)
