Hey I played it too. But I never knew the creator was and did not even care about it. But NGL, I made goofy ass characters on that app even gacha club. I mostly battled in gacha club. And I didn't know what a succubus was until I found out it was a demon that seduces men through sexual activity. And I was like, "wait what the F**K". Lillith was my favorite character in gacha world,Gacha verse/league. not because lillith Was a succubus, it was beacuse i was mostly fonded of female characters and my favorite color is purple.
