A Challenge called Avalanche

Synopsis

Construction workers at a remote resort development site are attacked by a massive shadow. A dying worker mutters 'Nadare.' Meanwhile, Daigo presents his groundbreaking research at an international biomedical conference, claiming he can grow a brain into larger sizes by placing it in a nutrient-filled container. Days later, Daigo returns to his remote research facility for the first time in a year, only to find it ransacked and his assistant Saigou and the deer Nadare missing. As Daigo reels from shock, Black Jack appears.
