@Isekaijin with start of this arc, i finally understend, why things in this manga like that - aaallll this situation with death game and human-eating is just background. All this characters and they behavior and thinking are just roles, like in theater. All this manga about situations. Its just happens, that in this manga, "roles", partly, remember what happens in previos scenary. Performances/plays are chained. If you look on this, like that is chained spectacles, not like this all occurring in real live, its all possible and realistic.
