Gothic Lolita Battle Bear is directed by Noboru Igushi, who also directed the quite mad movies Robo Geisha and The Machine Girl, although it looks like he's topped himself here. Here's the movie's description from the Stockholm Film Festival:
"Gothic lolita fashion enthusiast Yumeko Ayukawa, nicknamed Dameko, possesses the ability to merge with her talking pink teddy bear Buusuke to form Nuigulumar, a sexy leather-clad superheroine. Using her furry nunchucks, she must battle evil villain Takeshi, his psychic subordinate Kill Billy and a horde of 109 zombies, the highest number of the undead ever seen in a Japanese film.
Based on the works (both a novel and a song) of Kenji Ohtsuki, a popular musician in the Japanese subculture known as 'otaku', 'Nuigulumar Z' revels in director Iguchi's brand of twisted B-movie hysteria. Although it may not include his usual penchant for toilet humor, homicidal sushi and robotic geishas, the film doesn't skimp on his trademark gore, this time incorporating copious special effects in a particular homage to Japanese 'tokusatsu' (special effect) films and TV series."
