When it comes to the concept of age in anime then the boundary of human life and that of an immortal gets blurry really bad.
In reality, if a person lives more than 100 years he has achieved a big thing but for some anime characters, this is just a fleeting second of his life.
In a realm where storytelling transcends conventional boundaries, certain characters emerge as immortal.
This journey introduces us to the Top Oldest Anime Characters, individuals whose presence extends far beyond limit of time.
