On this day, Mario and Louis were resting at home when suddenly the mushroom came: the princess was kidnapped again. When they arrived at Kuba's castle, they found that Kuba knew nothing. Suddenly, the count appeared. He kidnapped Princess Peach. Mario was knocked to the ground, and the count made a different dimensional hole to suck Louis, Kuba and his men in. When Mario woke up, a colorful butterfly appeared in front of Mario. It took Mario to the Christmas Tower and met an exorcist (also the mayor). He told Mario that the dark forces were approaching. ....

Princess Peach woke up and found herself wearing a wedding dress. Kuba stood beside her in the groom's dress. The princess refused to say her wedding vows, and the count forced her to say "I do" with dark power. At this time, a chaotic "black heart" appeared. What is the real purpose of the count?
