Movie #2 of the Bad Movies Leap Day-athon
There's a set of powerful cursed mahjong tiles, a catgirl has one, she gets hunted by the magical girl in the cover, then she escapes, a montage of several magical girl types appearing / revealing themselves to hunt down this girl happens, then they find her and nothing happens.
Other than some cute character designs (BUNNY!!!!!) and some typical 1990s anime humor / gags, this OVA really, REALLY has nothing going for it. The game this is based on is about undressing girls by beating them at Mahjong, how they got a storyline about magical girls (and a cyborg) trying to gather cursed mahjong tiles to make their wishes come true out of that... makes no sense.
Oh and there's not even that many boobs to begin with. What a fraud.
