Consider the following:
When Agento-san first meets Inori in the tutorial chapter, and she recognizes Agento-san, she is not perceiving him/her as Agento-san but Aegiomon
When she asks you where the other person is (gender neutral in Japanese), she is not referring to Aegiomon or Agento-san, but Hiroko, who is implied to have been on the journey to the Digital World in past timelines by her dream side quest.
Does this solve the plot hole in the tutorial chapter of Inori recognizing Agento-san?
