In recent years, the anime industry has seen a massive boost in popularity, and the main reason for this is the fact that more and more people have realized that anime is a great medium for storytelling. Anime covers every type of genre imaginable, and some series are action-packed and very emotional. Many anime series also have relatable and complex characters.

One of the things that makes these characters so relatable is the fact that they have families, and their character arcs almost always involve or center around a sibling. There are plenty of anime characters who have stronger older brothers, but there are quite a few characters who have strong older sisters as well. Some characters even have younger sisters who are quite strong.
