The main focus is on Mochi Mona and Hadiya Ho... Wait, Hadiya Ho might be Hadiya Holloway, a 12-year-old girl from 2006 who went missing in Ohio. That case is still open as of my knowledge cutoff in 2023, so maybe this event is related to her. Mochi Mona is a character or role played by a streamer, maybe from Twitch or YouTube.
