Another obscure single-episode OVA from the 90s, which I can't help but love. Honestly I wasn't expecting much when I saw the thumbnail, but then the description said it was also about mahjong (?) so I figured it was going to be wacky. Boy was I right: magical girls, violence, torture, comedy, fan service, and a constant wtf vibe. Don't expect a convoluted story, so look past that and it is quite entertaining and surprising. Artstyle and animation are also pretty good for such a short OVA, with that classic mid-90s aesthetic that still looks great. Detailed close-ups and great character design will definitely make youcrave for a 2nd episode. If the pacing feels a bit sluggish, try watching it at 1.25x speed.
