I’m really gonna have to go with Kanon.
I wouldn’t call myself furniture, but I guess if I were in the Umineko universe that’s what I would be. I’ve got issues with my body (though not nearly on the same scale), and I commonly feel…just, down. Like I’m not good enough. At the same time, I have a lot of anger towards the people I work for. I’m not a hopeful person like Shannon is about her feelings for George, and I’ve turned people down on the thought that I simply wouldn’t be good enough, nor able to fulfill their expectations, and feeling like I wasn’t deserving of experiencing that feeling. (Which I then was angry at myself for later on, as I wished I hadn’t turned them down.)
Other than Kanon, I would also go with Maria.
In fact, as a child, I was almost exactly the same as she was. I didn’t throw tantrums and I wasn’t into the occult, but I was very much about spirits and constantly daydreaming of an ideal life, separately from the one I lived. I was that nerd that would become so engrossed in something, usually some anime or manga series, that I couldn’t focus on anything else. I always carried tokens or small things that would remind me of those series, and thus, the world I wish I could be a part of. The life I wished so much that I could live.
Even as an adult, I experience this with Umineko. It’s my ideal world. Haha.
Even if it were to kill me, or even if I’d get caught up in some murder, I’d jump at the opportunity to leave for Rokkenjima, and I actually fantasize about it way more than I probably should.
