Inuyashiki 5

Ichiro Inuyashiki is down on his luck. While only 58 years old, his geriatric looks often have him written off as a pathetic old man by the world around him and he's constantly ignored and disrespected by his family, despite all that he's done to support them. Just when it seems things couldn't get any worse, a blinding light in the night sky strikes the earth where Ichiro stands. He later wakes up to find himself unscathed, but he soon starts to notice that there's something a little different about himself.
