A Sister’s All You Need. Vol. 1

Itsuki Hashima is a novelist who's hopelessly enamoured with the idea of little sisters and is constantly surrounded by colourful characters. A world-class genius and love guru whose beauty almost seems a waste of her. She is a girl who's always troubled by her friendships and love interests and can't even find refuge in her dreams. A ridiculously talented illustrator. Each of them has as many problems and worries as the next and they never have a dull day together as they play games, travel, and work together. From the same author of the famous, I Don't Have Many Friends, Yomi Hirasaka!
