Fairy Tail x Nanatsu no Taizai Christmas Special

Hiro Mashima of Fairy Tail and Nakaba Suzuki of Nanatsu no Taizai team up for a special Christmas story, based on each other's work: Meliodas, Elizabeth Liones, and Hawk are visiting the city of Magnolia for Christmas, and Meliodas' offer to buy a present for Elizabeth goes awry. Upon returning from a job, Natsu Dragneel and Happy spot a suspicious visitor on the roof of their guild, which leads to an odd confrontation. (Source: MAL)
