Starting September 20th, Melissa, a gourmet boutique at the Rihga Royal Hotel in Osaka, will begin accepting reservations for "Sweet Nightmare" (5,500 yen), a cake perfect for adult Halloween.

"Sweet Nightmare" is a chocolate mousse drizzled with white chocolate, filled with raspberry sauce and vanilla-flavored mousse crème vanille. The bright red raspberry sauce inside spills out the moment the cake is cut, adding a touch of dark humor.

The cake is topped with milk chocolate and blackberries to resemble bat wings, and is surrounded by a sweet chocolate ring resembling lace.

The reservation period is from September 20th to 26th, and the delivery period is from October 1st to 31st.
