Tsukumizu’s 2019 Shimeji Simulation is an on-going surrealist slice-of-life manga.
Orphan Shimeji Tsukishima was unhappy at middle school and to avoid it, locked herself away in a small closet for two years. As high school approached, she reluctantly left her refuge. To her surprise, she discovers two small mushrooms — shimeji — sprouting from her head.
Shimeji has come to believe that effort is futile and hope is doomed to disappointment, She intends to pass through high school like a ghost, eschewing social contact and accepting whatever dismal fate life has in store for her. But her visualization of the all proves… inadequate.
