OOKIKU NACCHAUKEI JOSHI NO CHIISANA TATAKAI

Ookiku Nacchaukei Joshi no Chiisana Tatakai summary:

The unenviable daily life of a girl who can grow into a giant.
Kano Hashiki has a secret. When she gets stressed, she can physically grow into a giant. When she goes for a job interview, her suit can get ripped up. When she tries to take a shower after sweating, her butt can get stuck on the door. She has to relieve her stress, or she will unavoidably become bare naked and be treated like a freak show! Can this gentle but clumsy girl survive in this stressful society?
Her small-scale but earnest struggle begins today.
