Lumi alluded to being accused of something she didn't know anything about at the time a while back by someone, and it led to her being seen as controversial in the music scene. I believe she mentioned this person who accused her is more well-known in the music scene now. I believe she was talking about why she doesn't push as much focus on her music side. She also says it still pisses her off thinking about it to this day. I'm paraphrasing, and my short-term memory isn't very good, so I can't remember everything too clearly. When she's done with the Twitch stream, I'll post the timestamp of the vod in general.
I'm assuming she might be talking about the whole thing with the Cyberlive girls, in particular Menance.
