After Daili and Presia entered the meeting room and met with Qiqimora, Aiden formally handed over the task of surveilling them to Veronica.
Then, he quietly took out a pen in the corridor and paired it with the notepad in his pocket, on which he wrote "3:12—3:18, Qiqimora visit," and he briefly noted the content of the meeting and the subsequent arrangements.
Qiqimora's God-language abilities allowed her to completely erase her presence and seemingly even the memories of others who had met with her—this was far more advanced than Meiruki's memory erasure magic that only worked when one formed a contract specifically with her.
To be on the safe side, Aiden made a point of recording every encounter with Qiqimora in his notepad.
