Amano-ke Yotsugo wa Ketsuekigata ga Zenin Chigau.  

天野家四つ子は血液型が全員違う。

There's a belief that your blood type influences your character traits. For instance, Type-As are known for being serious and perfectionists, while Type-Bs tend to be independent thinkers. On the other hand, Type-Os are outgoing individuals, and Type-ABs can be seen as mysterious or complex. This 4-koma portrays four sisters from the Amano family who exhibit distinct personalities based on their blood types. Despite being raised in a similar environment, each sister embodies her corresponding type. The eldest, Asahi (Type-A), is meticulous and dresses fashionably to mask her perfectionism. Mahiru (Type-B) follows her own path without conforming. Yuu (Type-O) is extroverted and sociable, while Koyoru (Type-B) appears reserved and enigmatic. Despite their differences, the four sisters navigate life together as a family.
