most likely they never dreamed there a skill like that, also most of player play this game like normal MMO when its stated it's actually special VRMMO with advance AI personality, one important NPC for MC latter got injured by Player to point almost half dead, MC accidentally save her Kid from being killed by player latter when the kid tried to get revenge so yeah its VRMMO with Isekai flavor disguised as advance AI
about the event, Mari-nee actually end up being rank 1 using zombie tactic to the point her event score go zero while those guys who said to be pioneer while had decent event score end up in bottom barrel since they didnt help killing extremely stupid strong event boss that supposed to be weak if those guys pay attention to detail of pre-event situation
