Since she's a JoJo protagonist, she's got to be tough enough to not get disheartened even if she gets punched in the face. Sometimes she might be crawling through a ditch, or she might be falling from the top of a building with her legs wide open. It's a bit of a tight setup for a woman. But thinking about the differences in contrast, it actually seemed very interesting. Furthermore, she could be a person with great humanity like the Virgin Mary. I felt I just had to make the protagonist a woman.
JOJOの主人公なのだから顔面にパンチをくらってもヘコたれないタフさが必要だ。時にはドブの中をはいずり回る可能性もあるし、大股開きでビルの上から落っこちるかもしれない。女性にはちょっとキツイ設定だ。
でもそのギャップが逆に考えてみると面白いかと思った。しかも聖母マリア様のような大きな人間愛を持つ人。主人公は女性しかないと思った。
