Tetsuwan Birdy Evolution

After a period of two years lying dormant within Tsutomu Senkawa, an unforeseen encounter with their former adversary abruptly awakens Birdy. With Birdy once again taking on the forces of evil, the sinister truths surrounding the experiments carried out by the "Agni" corporation begin to come to light. They appear to be experimenting with enhancements to the human body, developing what they refer to as "beast men" to fight against the alien invasions associated with Birdy.
