There's an idea that your blood type affects your personality: Type-A's
are serious perfectionists, Type-B's are individualistic, Type-O's are
outgoing, and Type-AB's are strange. This 4-koma features the four
sisters of the Amano family, who are each very different from one
another in looks, personality, and even blood type. Despite growing in
the same environment, they each have a personality similar to their
blood type. The oldest, Type-A Asahi, carefully dresses like a stylish
girl to hide her perfectionism. The second sister, Type-B Mahiru,
follows her own path. The next youngest, Type-O Yuu, is very social and
gregarious. The youngest sister, Type-B Koyoru, is distant and hard to
read. The four sisters go through their daily life together, each very
different from the other!
