Kono Bijutsubu ni wa Mondai ga Aru! (2003)

A small town is overrun by ankle-biting-blood-sucking DWARF Vampires. Things get complicated when the vertically-challenged coffin-creepers get their itty-bitty hands on a sword with the blood of the last slain Tall Vampire. With this relic, they can create a super-race of SHAQ-sized Draculas out of any tall human. Now, the half Vampire / half Human, Drexel, is the town's - and the world's - only hope to stop the countryside invasion of the mini-Demons. There are no SHORT fixes to this TALL problem.
