Luke Halliday writes:
"The works of Osamu Tezuka are simply legendary. Princess Knight is a series that comes with the pedigree of the God of Manga himself. Tezuka is the visionary that helped create manga and anime in the form we know it today. One of his earliest works was Princess Knight and at nearly 50 years old, it isn’t exactly an exaggeration to say that it shows its age.
While it looks its age, there is a sense of timelessness to Princess Knight that transcends time and space entirely. Princess Knight serves as a gateway to anime’s past, giving a glimpse into the brilliant mind of Osamu Tezuka and his creative genius that set the foundations for modern anime."
