is there a way to induce kin memories
Hmmmmmmm this is a good question which will get 5000 different answers but I will answer as best I can from personal experience.
Personally, I believe so. I feel like I should clarify that I have a daydreaming issue (probably immersive daydreaming) so that heavily impacts how I engage with my kintype.
Anyway. For me you literally just gotta surround yourself with stuff that reminds you of the kin. Admittedly I use divination to get a head start (ie 'is my canon noncanon', 'is it a magical girl au', ect) and once I have the basics I just surround myself with stuff that reminds me of it.
Like, say I want to develop the memories of the magical girl Fyodor canon. I would play my magical girl Fyodor kin playlist, get the memories I have already written down and try to focus on parts that I don't have answers too. Like my relationship with Nikolai. And then I tend to write, I just jot down what comes into my head, sometimes it's nonsense that makes 0 sense to anyone (including me) and then when I finish zoning out, I know that the session is over. Then I have to make sense of what I had written and how it feels and what I can envisage.
Sorry, this probably isn't much help, if you need more details please lmk (also sorry if this is ass we are blurry as hell rn).
