Adult swim has gone to shit, I’d avoid it as it currently is - the golden age has long passed. Inuyashiki is not at all related to Inuyashiki, lol - they’re two different names. The premise is this, and I know this is gonna sound fucked, but stay with me: an old man is walking in the park when he suddenly fucking explodes and dies. Some aliens accidentally killed him, and they’re like “oh shit, we gotta fix this... let’s rebuid him?” Next thing you know, you’ve got a motherfucking super grandpa that goes out and starts saving people’s lives. The cool part is that he’s not the only person this miracle has happened too, and the other person is actually a psychopath that starts mysteriously murdering people, which the old man vows to discover and bring to justice. It’s a blast and it’s all free to watch on Youtube. Oh, and it’s made by the same guy that made Gantz.
