But Allen didn't want to become the admin of the chat group just to complete the Main Task like some automated robots. He wanted to enjoy himself in the process of completing the Main Task.
Although the Heretic Gods could pose a threat to him, Allen thought of the Second Main Task as a vacation for him and his lover (Iris) along with his friends (chat group members).
Allen had already foreseen that the Main Task would become more difficult in the future and that was why Allen had the idea of enjoying himself in the Main Task since he would no longer have that enjoyment in the future.
