Christmas Costume (クリスマス・コスチューム) was an item from YGGDRASIL that appeared in Mass for the Dead.


A custom made item created by Pandora's Actor using materials from the Treasury.


A Christmas themed outfit with a short red-furred cloak over the shoulders. It also includes a small red cap with a skull stitch on it. White garters decorate the legs and on the arms are sleeves with bells attached at the wrists.

There are several other costumes in the Christmas series, worn by Sebas Tian, Narberal Gamma, Hamsuke, Aura Bella Fiora, Mare Bello Fiore, Lupusregina Beta, Entoma Vasilissa Zeta, CZ2128 Delta, Yuri Alpha, Solution Epsilon, and Evileye with varying cosmetic differences.[1][2]


According to the game information, Albedo's costume increases physical attack power, magic attack power, and damage to "Devil" species.

The outfits worn by Aura and Mare state provide buffs but also includes equipment like the Candy Cane Gun and Candy Cane.

The costumes worn by the Pleiades maids Lupusregina, Entoma, and Shizu have various buffs and are completely resistant to cold air. Originally, they were formal dresses for "Christmas", which is a special day, but they are also first-class items that one can wear everyday if they pursue only the functional aspect and do not care about looks. Lupusregina wields a silver tray decorated with cake for a festive mood; Entoma utilizes a Thousand Lash Bug dressed in Christmas colors, and Shizu wields a pair of pistols.
