Late to the party but just started this anime. Surprisingly good if you don't mind girls with weak bladders.
Example 1.5 Prompt for the insulator suit(The red bodysuit): arrester_blanket, 1girl, insulator_suit, hairband, long_hair, glasses, red_bodysuit, black_gloves, white long_sleeves

For Pony you can probably just prompt as below but if that doesn't work add terms from the 1.5 prompt:

arrester_blanket, insulator_suit

For clarity the title image for the Pony Version had the text edited in. I wish I knew how to get clear text in Pony.
