EP7 spoilers:
The Chiru figures I got from an artist that makes figures, she’s a friend of a friend so I wanted to support her AND get myself some Chiru figures. The pins are part of a set of pins, it was quite hard to get it, but I have lots of Umineko friends around so I could take the ones I wanted and take the ones I want. The plushie I sewed myself, and the doujins I bought while in Japan/Japanese stores!
