Oh and about the positive trigger(the dr ink) that made the girl alter comes out. Please don't use this trigger casually and if I must say only let the person trigger him/herself , this is not a really good thing. It's better to talk to the alter that is on the front first and ask for permission or ask the alter on the front if the alter you want to talk want to front or not.The positive trigger can cause mental burden to the body so if possible don't use it without the alter permission !!
Correct me if I'm wrong but after doing some research, I found out that it's natural for people with DID to sometimes have their alters integrate o: like for example theres this youtuber, DissociaDID, whose channel is dedicated to informing people about DID and debunking myths/stereotypes about it, and when she started her channel she started it as one of her alters, Chloe, who later integrated with another alter, Nina, and they became Nin.
Also, after reading this manga i decided to research a bit, and apparently when people with DID start going to therapy/begin their healing process where they learn to cope with their trauma, their alters can all slowly integrate into one (who is either going to be a "new" alter, or a combination of their alters). But please correct me if I'm wrong because I'm not a professional, and this is just something i found from research. I'm interested in how this author will handle this, though
Well, he didn't really mean to trigger her right then, he was just asking about it
Hmm they took the approach of making the alter dissapear one by one it seems. Which is okay but in real life to make an alter disappear isn't necessary a good idea and have a chance of causing another mental trauma. That's why you see people gaining on alters not alters dissapearing but its a manga, who am I to judge (☞ ಠ_ಠ)☞
