Ok so riddle me this... how can a person who was once a soldier not be able to do/know any combat or battle tactics?? Like did she forget or was she not a soldier in her previous life???? Im so confused like she could have been a badass character with her knowledge!! ヽ(`Д´)ノ

Yes, I read it. But seeing as I failed to write some of the important things to support my comment, cuz I was running on 4 hrs of sleep and soda, let me add the points I forgot.
Her current body is VERY weak and needs working on. She uses ARC, the AI, to help her but other than that we do not see much of her own battle strategies as often. Like the most we have seen is her try to gather money, talk about what she needs to do.
She is an awesome character but the point I'm trying to make is that we never see her act like a soldier. I want to understand what the author is going with her but can't at this moment and it's like she could be so much more if she shows off her battle prowess. but we shall see what she does in the coming chapters. I really want to see her kick her sisters ass and get revenge! (╬ ̄皿 ̄)凸

I'm getting the feeling that the girl either moved or she passed away. In Japanese society, it is sadly not uncommon for young adults or even older adults to take their life because of the hateful nature of others. To me, this does hit home to a point because mental health is looked down upon in this day n age. To anyone else what he did might have seemed like a generic backstory but tbh this is something that does happen.
Yukino truly wanted to help because he saw someone being bullied but in doing so he caused more harm than good. It made him avoid making connections with others, which is sad. It is not a disappointing plot point but a very real-world relatable issue.

Listen In not sayin give me their names but i want them names and i just wanna talk... with a knife... at Denny's... in the parking lot... @ 3 am.
But on a serious less murderous note. Those ppl sending death threats are not true manga readers like if ya dont like a manga ok voice it in the comments and then walk away. Don't be an asshat and try to ruin others enjoyment. Or better yet discuss it with others to understand where the mangaka is coming from! Like shit man sending death threats is so fucking lame ya'll just acting like immature idiots on the internet!
If anyone finds out about who is sending the threats. Let it be known that ya'll are not as safe behind the computer as you think you are. Hell hath no fury like a bunch of manga readers in a pandemic.
