Mai x Mai? Sunao ni Narenai Imouto-tachi to no Ecchi na Kyoudou Seikatsu

Описание: Rikuro's of the hero, lotus and sister live a substantial two people.
Recently, while suffering from my younger sister who strangely tsunzun, I lived in peace as it is.
Such a holiday -
Rippled cherry blossoms somehow in a panic (as usual) will be beaten up roughly.
When I go to the living room in a hurry, there was Yuli, my sister's best friend.
When you hear stories about what it is
"I have become my brother's sister since today."
What to say, to live together without knowing the translation.
Sister who suddenly increased suddenly.
And, a sister who is getting even moody (genuine article).
However, the attitude of Rizhao will change gradually for Yui who is inclined to taste and lotus.
"...... everything, my brother is bad"
Every day that was supposed to be peacefully exciting ......
And it turned into a sweet and eclectic life.
