>>3504209I actually feel the opposite way. This is the same girl that cried about failing to make rainbow udon and then had her mommy and sister help her for the next attempt. She cried during a singing stream after her fans showered her with love and called them surrogate fathers. I think a lot of folks have also heard what Coco and Kanata think of Haachama as a person. She's a sweet girl that puts up a tough front but has a surprisingly fragile interior.
During her 1/2/21 ASMR, Chammers reveals part of the reason she does shocking things is because the audience reaction helps reduce her stress. The streams you posted fit this behavior. Additionally, Haachama's shock content is one of the few ways she feels she can distinguish herself from her colleagues. Any escalation of their intensity I would first attribute to spectacle creep instead of self-gratifying sexualization or derangement.
