Overall. This is just an incredibly fun manga to read. There’s nothing too deep or tragic going on, what drama there is is played out well and it’s basically just a great time. Story wise, the premise is around an eight out of ten with maybe seven out of ten execution but I don’t really read it for the story. I read it for the insane moments such as (mild spoiler warning): Killing a man with his actual heartbeat, Defeating the incarnation of the god of time, Breaking reality with a sword, Being more than immortal, Stopping time to sign autographs, Killing a man multiple times to teach him a lessonabout bonds.
And basically crazy shit like that every other page.

It’s not groundbreaking or something special in a way something like Attck on Titan is. It’s just really. Really fun.
