Even in reality sex dolls are so expensive and none are humanoid like this one, if there was one like this, I wouldn't mind paying for 60 months or even more of installments.
Yashiro is a sly fox. He pretended he can't stand on his own feet because of giddiness and every time naive and loyal Domeki caught him in midair and for last time after getting enough trust of Domeki he grabbed the gun. Poor Domeki, How helpless he felt, but he loves Yashiro, so he just let it go.
So everything finished. I find it burning by fire is more painful than being killed by a tool, other than torturing.
