Kateinai Kaizou!! Ecchi na Ane no Tsukurikata

Break down big sister, domestic-style!!

A high-ranking career woman with a good reputation
... at least in the company of others...
at home this big sister is a disrespectful, mean jerk
especially to her little brother.

When their father is reassigned overseas,
their mother is only too happy to go with him to
escape home life with an insufferable daughter...

She'll going to make little brother's life a living hell...

So he takes action first.
