“Would you like to go kill some monsters with me after a long time?” My childhood friend Mami-chan, who I met again when I returned home for the first time in several years, has become a dried-up NEET who shuts herself in a dirty room. – Her hair is unkempt, her clothes are sloppy, and her big breasts are wasted. – She has an irregular diet and doesn’t meet anyone. – She is a mourner who has given up on being a woman, but… there is an electric massager lying in the corner of the scattered room.
