Rimuru thinks that with the help of his powers, he can stay hidden in shadow and uses a magical beast that can fly to do the Santa job. Great Sage interferes and analysis the characteristics of Santa Claus’s movement. Great Sage reminds Rimuru that Santa Claus stays hidden, leaves presents by pillows undetected, and deliver many presents in a day while hiding from children.

Rimuru wonders if Santa from another world does those movements. Rimuru asks if there are any Otherworlders in this world named Santa Claus. Shun, Rigur, and Milimi seem to have no clue.

Rimuru realizes that every Christmas, Rigur asks the same questions. Rimuru told Rigur that Christmas is the day they celebrate the birth of an important person in history. He replies that at Christmas, they get a fir tree, cake, turkey, and presents. Rigur started to wonder who is that person and thinks that they must praise that person. Rimuru replies that they don’t have to be one of his believers. Rigur wonders why they don’t have to applaud that guy. Rigur asks where this Santa person is.

Rimuru replies that Santa sneaks into the house at night doing his nightshift job. Rimuru thought that Rigur wanted to ask him about that vital person. Rigur believes that the person who sneaks into the house at night is a thief. Rimuru realizes that it will be difficult to explain why Santa sneaks inside the house. He remembers that in the human world, it was customary for people to believe the Santa Story. Rigur waits for Rimuru to give more explanations. Rimuru talked about drinking and eating at Christmas.

Rigur gets excited to hear about the presents and thinks Santa will give him more stuff when Christmas arrives. Thus Tempest began preparations for a big Christmas party. The next day Rimuru taught his nation how they make decorations for Christmas. Shion wonders if the Christmas tree will light up, and Rimuru told her to count on Dwarf. The Dwarf guy told Shioun to wait and see miracles in the evening. The Dwarf crew got dressed like Santa copying Rimuru and commented that the long beards make them look like old geezers.
