Using crimson as its image color, the comprehensive brand "SV" has rapidly gained popularity for its accessories, clothing, sweets, and so on. However, the CEO of this company, a man named Aviel Kyogoku is actually a vampire digimon named Vamdemon. His purpose is to gather beautiful women influencers to suck their blood and manipulate them through his bats.
Thanks to the popularity of Lirurun, Ruli has been invited to taste crimson deserts this coming Sunday, however, she must come alone. Angoramon finds this suspicious and meets with Hiro and Kiyoshiro. While Ruli attends, everyone else is watching outside.
While inside, Ruli recognizes Dracumon! He wants to be the one to suck Ruli's blood. He angers Vamdemon, who quickly puts an end to him. Ruli slaps Vamdemon with her purse and escapes to the roof. Vamdemon has let Hiro and the others in. They meet with Ruli on the roof.
Gammamon and Jellymon evolve, but Vamdemon is too strong. The two are easily taken down. Betelgammamon is infected with a virus by one of Vamdemon bats. Every time he takes damage, Hiro can feel it. Hiro sees Betelgammamon's eyes turn black and fears what is about to happen. He says that they will get through this together. Suddenly, Betelgammamon super evolves to Canoweissmon!
Canoweissmon is able to overcome Vamdemon, who transforms into bats and escapes with Matadrmon and Sangloupmon.
Once the evil digimon are gone, Hiro admires the beauty of Canoweissmon.
