Summary
Mr. A is a Parasite who views Shinichi as a significant threat, a perception shared by Migi, who dismisses him as lacking intelligence, and Reiko, who refers to him as a fool. He completely lacks subtlety or a sense of deception, openly utilizing his shapeshifting abilities in public spaces because he relies on his capacity to fight, flee, or alter his appearance to escape any trouble. His host body serves as the father of Reiko's child. When he attempts to hunt down and kill Shinichi at school, Shinichi and Migi are compelled to engage him in battle, severely wounding him before they are forced to retreat before he can be fully destroyed.
