In the beginning of Kuroshitsuji II, Sebastian entered the Trancy Manor disguised as a wanderer needing shelter from the storm. However, when he criticized Claude Faustus for leaving a drop of sauce on the side of his dinner plate, he blew his cover, alerting Claude that he is Sebastian Michaelis. This resulted in a battle between the two demons when Sebastian took the “New Moon Drop” tea box from Alois Trancy.
Beautiful cosplay! I would not mind getting my tea served from this cosplayer at all. Thanks to Feenie for sending this in!
