I'm not familiar with this series, can anyone explain to me what the purple liquid is and what's the context?
1. The three girls on the top are your not so typical mahou shoujo 2. The aqua haired one gets an idea to use a chastity belt and chastity bra (both from an uncuttable stell - as broken cutter suggest) to protect her from evil tentacles to whose attack she always was particularly.... ehm... sensitive 3. Mission successful...? 4. Oh look - the villains somehow got the one and only key to her new shiny gear... 5. The purple liquid is a strong acid 😅
