A torchlight which dropped by said missing policeman was founded with sample of the mysterious kidnapper's hair. Later, when GUTS were returning back to base, they found a woman who had fainted on the road. Munakata detected a bite at the woman's neck as they brought her to the base. As told by Horii, she was still alive but her body temperature was similar to a corpse's. The woman awoke that, growing fangs and her face turned pale; She knocked out two TPC personnel and attacked Commander Iruma attempting to turn her. Before the vampire could bite her, Munakata arrived in time and forced her to retreat from the Dive Hangar with the vampire diving into the sea.

Powers and Abilities

- Superhuman agility: The vampires could perform numerous acts of inhuman agility, such as jumping extremely high.
- Bullet resistance: The vampires could resist bullet attacks even the GUTS Hyper pistol which fired laser ammunition.
Like their master, they were vunerable to sunlight, artificial or genuine, contact with such an energy caused them to combust in blue flames. Their virus also could not work on Daigo due to having 'too much light within him' (His Ultra DNA).
