Blue-haired characters are known for their composed demeanor and tranquil presence. They rarely intrude or pester, but instead, merely make themselves known. Blue-haired characters will often represent patient and understanding characters, hence why so many characters feel comfortable around them.
As natural peacemakers, blue-haired characters rarely stir the pot and extremely loathe the idea of creating conflict. Since they don’t like being in the spotlight, blue-haired characters will keep to themselves and come across as reserved characters. Though they may lack a strong personality like red-haired characters, they possess a unique spirit.
Furthermore, these characters thrive on being organized and don’t like to upset the status quo. As a result, they are very predictable. However, due to their love for order, they can come off as rather controlling.
In this list, I will detail the best blue-haired characters in anime. Beware of spoilers.
