The actress in question is Sumire Kuramoto who debuted in 2020 at the alleged age of 20. She has characteristically youthful looks and, while not as overtly loli(bait) as some other actresses, predominantly stars (and excels) in schoolgirl roles. However, it has come to the sirs' attention that she is making increasingly frequent appearances with acclaimed mature woman-centric studio Madonna which, in turn, have involved young, newly-wed housewife roles instead. This has been a cause for alarm for many sirs (especially those who prefer younger-looking talent) as it appears Madonna and the mature woman genre as a whole has been encroaching upon the already limited pool of JK-appropriate actresses and, in a sense, fast-tracking them towards increasingly mature roles.
Fans of mature women and the studios which exhibit them have been looking on these developments with glee. Since there are other posters who -either jokingly or earnestly- feel resentment towards this population of self-proclaimed "hagchads" for their seemingly disproportionate and ever-increasing sphere of influence on the thread and perhaps even the adult video industry at large, cases such as Sumire have only contributed further to the ongoing conspiracy theories in relation to the hag movement and its unbridled expansion. The exclamation "they [hagposters] can't keep getting away with it!" is commonly attributed to this sentiment.
