By the way, here is a deepL translation of her apology letter as her pinned tweet.
"I would like to take a moment of your time. I would like to take a moment from everyone to apologize for the inconvenience and worry that my delivery has caused. I have caused you a lot of worry and discomfort since the delivery I made at 1:00 a.m. on 9/11. The reason for this behavior was my own impatience and lack of thought. I had not been able to deliver the most recent delivery to my satisfaction, and I was late for the collaboration delivery, and I blamed myself for being impatient that I would be abandoned. I was more impatient with the outcome than I should have been, and I acted without consulting anyone, without thinking about the consequences of doing so. I haven't decided in detail what I should do yet, but since everyone in room 201 hasn't given up on me yet, I want to think carefully about how I can make amends to everyone and how I can deliver something that everyone can enjoy again, while consulting with everyone properly. I am truly sorry about this. Thank you very much for taking the time to read this. Ishinomaki Tsumuri"
