Hello lfan,
Yes, I do remember hearing about this one from my good friend Shehulk_Fan, and wanting to see it as well. Sadly, with all my knowledge about superheroines abroad, this is one of the few I haven't been able to get my hands or much info on. I do know that Klenk is a schoolteacher -In Britain' who teaches class bny day, fighting crimes as Superklenk by later day (lol!) The one pic you found was probably the same pic I seen too. But, there was another show from Japan called SuperB -the TF was halarious, anyone heard of it? -and I'll see if I can find anything on SKlenk-
