Christmas party

CHRISTMAS PARTY!!! In black order it was being arranged... Well lenalee need help. There was only one person who can help her with out any trouble. But she was the badass girl of the order. Everyone feared to talk her for some reasons. What will happen when "Rin"(my oc) will help them? What will happen when Lavi would make any trouble and drag Kanda among with him? What will happen when both Rin and Kanda will be locked up in one room??

(I don't own DGM nor the characters I just own my oc please support me if I do any grammatical mistakes)
