Ultraman's brother

Ultraseven is a hero made in Japan whose brother is an another famous hero Ultraman.There is one story in it which was banned on air because the alien in that story has a horrible mark of wound in his face suffered by the atack of an atomic bomb and the association related to atomic bomb sacrifices had a claim on it.You can easily imagine that as a result this film became a rare item among the Ultraseven maniac.

Today my friend told me the website where online free watching of this film is available.I wonder why that website came to obtain this rare film and started to offer such grateful service.
