A little OT, because I liked the novel:
While the Animu was a white pill at the end (and had it's light moments till Yamazaki was gone); the book was very unnerving till the end - but comfy af. Are there similar light novels from Japan? I currenntly only read Japanese literature, it "gets me", it is poetic, calm and it doesn't try to insult me.
But I could never have been be a real Hiki, parents wont support it. And maybe it's for the best ... if are able to leave your house at least for groceries and other necessities, it's fine - but when I moved out and was a fulltime NEET, I had phases where I wouldn't leave the flat for many days. Deliveries are costly these day. I like to work part-time and get something done, it helps me. Sato had his 7/11 and whatever, no Ausländer at night, so it's save for him in Japan to leave the house at night. That's no option in Germany.
