俺、彼女、姉 / ああああスペシャル

It's just a manga about three people, a dragonborn sister and brother, and the brother's girlfriend, a human woman, living together in harmony.
It is a work derived from a series called "Optanion", but
even if you don't know about "Optanion", I tried to make it enjoyable.

I used digital offset printing for the cover, but
the text is printed by a copy machine.

The book is bound by hand.
Please understand that there is a slight difference in the finish of each book.
(We apologize for the inconvenience. For now, the language is Japanese only.)
