Btw, Nerd wanted to use the points to get out of the hunt not Kyou. Wouldn't make sense for Kyou to leave since he was still interested in sadistically killing aliens.
And you seem to have misunderstood me a little bit. I meant the people from Tokyo who have already fought aliens are the people that left the team first. Katou, HS, Takeshi and even Kaze starting fighting aliens while the rest of the team were just spectating.
