I did have to hook up a pad to make this game playable at all, but once I did, I was having quite a good time.
It features 5 playable characters, each sporting a decent variety of specials (SFII input style), and a special meter that allows for some relatively impressive combos. To my surprise, Metal & Lace 2 is actually a decent fighter. Images of this GIF above are why I tracked this game down, and I expected a terrible fighting game with some lewds thrown in for good measure.
I believe it was also released on DOS or Win95 or something, but I've only been researching PC98 stuff, so I'm not sure there. Metal & Lace 2 (Ningyo Tsukai II) is a fighting game released for the PC98 by Forest in 1996.
