This novel was so good. All the way up until the whole yuki "tricks" the slime and becomes the ruler of heaven. What makes no sense is that the slime can think at light speed move at light speed and do a whole bunch of other stuff but he cant beat a almost ordinary human.
To me it felt like a cop out, I know that there has to be a heaven vs the world battle but it feels forced. What worse is that the slime was all gun ho about finishing this and brought a crew of demons that defeated army and couldn't stop this small 3 man group. I wanted to keep reading this but ill have to wait for the next arc cause im done with this hole yuki business.
I heard that the Light Novel had a change to this but in the end yuki becomes the ruler of heaven when he should have been taking out after the slime confronted him like teleport to him and wam/slash/bam job is done in all of 1 second.
