I thought the outfit is cute and that is how actual Japanese girls who go to Harajuku dress so I don't really think it's inaccurate... The western idea of "Harajuku Fashion" is based on early 2000s fashion trends that are no longer popular in Japan.
So, from what I understand about her illness, her different joints and appendages (arms, legs, knee caps, jaw etc.) routinely dislocate from her body leaving her in intense pain and immobilizing her. I don't really think that leaving the house to go gallivanting around the the country is easy for someone like that. I think she has to work really hard to do things in her daily routine because she is constantly in pain in addition to dealing with the psychological impacts of her long term illness. If she chooses to sit at home it's not on account of laziness. I am sure she would love to go exploring but you have to look at the reality of what she must be dealing with. I think we should have more empathy for others instead of just judging them based on what we want them to do with their lives.
Second hand shops are very very selective in Tokyo and only typically accept brand new main brand clothing if they are giving you money for it. Even if it is a well known name brand they will give you around 1/4th of the price they will sell it for if they take it at all. She is not wrong in saying that they probably won't accept it. Also, there aren't really any charity shops for typical donations because once again, there is no market for it. Japanese people aren't as in to fast fashion and don't buy as much clothing as Westerners.
Japanese colleges are usually really really lenient on grading. An A can be 100-85 B 85-70 C 70-55 D 55-40. Most of grades are based on attendance and participation. It is really easy to do well and basically impossible to fail. If she fails out or loses her scholarship it means she had to have tried really hard to fail.
She seems to treat other people (friends and esp. romantic partners) like crutches to the point that they can't handle the clinginess/ neediness and run away. She works so hard to be a bad bitch to hide her weaknesses/fears/insecurities. Everyone has weakness of all sorts, but a lot of people learn how to deal with them in a healthy way (talking with friends/therapists, by exercising, healthy eating/sleeping habits, and abstinence from all substances (including alcohol)). I think a lot of her habits are self destructive to the point that she has normalized it as a "healthy" part of her life. Things like anxiety and depression get worse with the use of alcohol and caffeine. Yet here she is every other night going to a bar and staying up until ungodly hours drinking and thirsting for low quality dick. You're not going to find anything good at a bar/club. On a side note: If she is serious about meeting a good man, she shouldn't date these gaijin fetishers who are constant bar/club goers. They seem to have low motivation, bad life habits and are all around flakey individuals. Even if she was in a more stable place in her life they wouldn't be a good match. If she really thinks herself to be a god she should stop letting these type of men into her life and also aspire to be the best version of herself instead of blaming everything else for her problems.
I don't have personal experience but my understanding is that any time you want to stop taking psychotropic you should be working with a medical professional. Apparently a lot of side effects can happen and some of them are really severe/ harmful, and potentially worse than what they are supposed to be treating. Even if she doesn't want to take medicine anymore she really shouldn't just be taking matters into her own hands. Medicine can do some strange things if misused.
You need a degree to teach English as a instructor under and instructor/ specialist in the humanities visa. However, she can work part time under a student visa and for freelance teaching of english you don't need a degree. Lots of men would love to pay her for "English lessons", that how she can get the big bucks even if her lessons are sub-par.
A lot of Japanese students want to be a fashion/makeup/hair/influencer something, so her choice is pretty garden variety. Except for a few very competitive public schools (in japan public schools are more prestigious than private ones) they are basically a waste of money. Since her social media career is going pretty well she might be able to loop it in to some opportunities though.
Fun fact another way to call a quiz in Japan is Sho-testo which literally translates as small test aka quiz. So maybe she hears that and doesn't understand the phrase so she thinks its an actual test and that she should get an hour for it....
Sally Amaki is ethnically Japanese. I am sure her visa situation is completely different due to the fact that she is likely a Japanese citizen. Also Kenna doesn't have appeal to a Japanese audience. By Japanese standards her height, weight and body type are normal. Her appearance, while on the cute side is relatively normal. She doesn't have any special skills (singing, dancing, or modelling) and she has no esteemed college degree which she can use on some game show to answer questions (like some shows where graduates of top universities compete for prizes). There is nothing special or unique about her that doesn't already exist here. There are plenty of people in Japan with better Japanese (including of course Japanese citizens), better attitudes and more drive to get the limited opportunities that do exist here. Therefore, she is not going to get a contract to be a talent or idol. It's not even a possibility.
People only have JLPT level N◯◯ if they pass the JLPT. Otherwise it's all conjecture. People can be a fluent speaker in Japanese but if they can't read kanji up to a certain level they can't pass. Likewise you can pass the JLPT at the highest level and not be able to speak a word.
