A new guard has come to Building 13. 
It’s Hajime Sugoroku’s brother(?), Hitoshi Sugoroku.
This takes Hajime by surprise and he tries to lecture Hitoshi to go home, but he has already been hired.
Meanwhile, Uno and Rock starts doubting Hitoshi, who can pull off a woman’s guard clothes nicely, is actually a gorilla’s... or Hajime’s brother. 
To find out the truth, the 2 announce the beginning of Cell 13’s customary game of tag.
Big Brother is not a vicious gorilla!
