Katou Izami lives a quiet life with his Mom, step-dad, and step-brother.
When their parents leave, tensions rise and the step-brothers end up fighting another.
Tenjou handily defeats Katou and forces him to cosplay as a cute Japanese girl (Koakuma from Touhou.)
Afterwards, Katou is quickly feminized into becoming a girl full-time.
The crossdressing/feminization is forced throughout the entire book with a psuedo mind-break element as well
as the younger brother accepts his fate.
There are rape/forced themes as one brother is dominated by his step-brother.
