Japanese teenagers going to high school a long way from home and basically living in apartments alone is a thing that happens in Japan. It's not super common, but if you live in a rural area like Sinon does to go to a decent school that's what you'd have to do. 

That's on top of her needing to get out of her hometown at any cost.

I remember.
Her grandfather and mother can't arrange another flat for Assad Shino? If this flat is too weak security.

I deleted the previous post due to gross misinformation.

For the record, no one even broken into her apartment. Shino herself let Kyouji in. That's not a break-in.

To answer your question, Shino spends a large portion of her allowance on GGO, so she couldn't afford to get a better apartment. Nor did she ever have the need for it, seeing as she's never had any issues with anyone breaking into her apartment. Not even with Kyouji.

OK I understand.
As for Kyouji, I know that she let him in.

A user who wrote this, so it's not true?

step down or I will have Fandom remove you. What happened is Kyouji broken in and than he went out and waited on her belcony. He did not knock on the door and if he were watching the stream it would take 30 minutes to shut down his computer, get on a bike, and get to Asada's apartment. So I was off I was going to edit it. After Asada won GGO she logged out which takes two minutes. If Kyouji was watching the stream from his computer he would not get there in time. HE BROKE IN! he was watching Asada's monitor and when he found out XaXa failed he went out onto the balcony and waited all Asada had to do was open her door and he came inside. If you censor me again I will file an official complant to the VSTF and have you removed and your Discord server shut down also I will have Fandom disable all your alts and bots so you can not hack other peoples computers.   

People can watch videos through a phone. The story takes place in 2025, not 2005. There's absolutely no reason for him to break in to watch a video. Nothing in the books ever said that he had been anywhere in her apartment before she let him in. It's possible that he was there and then rushed out when his brother was killed in-game to avoid suspicion, but nothing in the books confirms that. He could have just as simply waited outside and only broken in when the time was right.

This is a wiki, a site where people come to learn facts. If you presented your headcanon as a theory/speculation, I'd have no reason to remove it. But when you repeatedly present headcanon as facts on a wiki of all places, it will be removed. Especially when you keep necroing month or year old threads to post some off topic stuff that's filled with inaccuracies at best, gross misinformation at worst.

OK I understand.
And delete my post question?

Him being inside her apartment when Death Gun shoots her so he can kill her at that exact moment is the whole modus opporandi of Death Gun

That's why there are 3 different Death Guns operating in concert, so the moment the one in game shoots someone they appear to disconnect in the game. All the deaths we're shown on screen happen this exact way. To say he was in her apartment isn't wild theory but what is implied and discussed in the novel and anime.It's how Xseed, Tarako, and Pale Rider all die, shot with the blackstar and disconnect seconds later, die in reality at about the same time.

Not sure, if it was written already...

Shino's mother is not exactly affraid of Shino- she still treated Shino as a younger sister, when Sinon moved away from her little town to the bigger one.

Shino moved on her own from the smaller town, because everyone there knew, what she did, as it seems. People were very aggressive about her, so she moved to a place, where nobody knew about her background.

Her mother had a mental breakdown, so now Shino's mother doesn't feel like she is an adult woman. She thinks that she is a child. And children do not have responsibilities and children themselves. So Sinon's mother thinks that Shino is not her child, thus, she doesn't have to take care of Shino.

It is very good that there were other people to take care of Sinon and her mother. Imagine, if there were none.

Except that those very novels specifically state that all the kills till then were performed either by Kyouji's brother, or Johnny Black; Kyouji himself only went for Shino's apartment. And in those very novels, Kyouji himself has specifically stated that he had actually planned NOT to inject the drug that day even if it went against their plan, because he thought that Shino would be his after the tournament anyway...... until Kirito got into the picture. So, just because the the Death Gun plot involved breaking into the targets' house doesn't automatically mean that he actually did break into Shino's house when he had no real reason to because he wasn't even planning to follow the script. It is possible that he did break in after all the cave stuff... but that's not a certainty at this point. And, unlike what Geomodelrailroader is claiming, Kyouji most certainly neither lurked in/escaped through the balcony (he had a key to get in/out, so why would he need the balcony), nor did he need to be in the house to watch the stream, since he was watching it on a phone.
