The first valkyrie ever... Very very 70s. The influence of Mobile Suit Gundam is also notable here. Some parts of the "Breast Fighter" seem taken from Zeon aircraft...

No wonder since Kawamori Shouji was member number 1 of a Gundam fan club called "Gunsight-1" in his college days...

I just hope the powers-that-be decide to release this as a toy someday...
