The eggs purpose is to remove the memories about Yuuko-san. All the Doumeki gets to inherit the egg, all waiting for the time where Watanuki is ready or, anytime at all that might require him to forget Yuuko. But alas, even after 100+ years, he choose to remember her.
Will we ever know the purpose of that egg..
I comeback here from time to time to check if there's an update or like to re read it again.. I so love this manga
