Cafe employees Vlad, Luke, and Toryu help Ton search for the culprit. When they find the thief, they transform into inhuman vampires, wolfmen, and vampires...
Ton is surprised. However, she learns the ring from her great-grandmother that she always wears holds a major secret.
Every time you defeat one, 
there's another to take its place.
.كلّما هزمت واحدًا، يأخذ آخر مكانه
Sobald man einen besiegt,
nimmt ein neuer seinen Platz ein.
Cuando acabas con uno, aparece otro.
Cuando acabas con uno, aparece otro.
Plus on en tue, plus il en vient.
Sconfiggine uno
e un altro correrà a prenderne il posto.
Sempre que um cai,
outro aparece no lugar.
Сколько ни побеждай,
а всегда новые вылезают.
