Just because he's a slime and was defeated doesn't mean this applies to all slimes in general.

In Yugioh for example; a Slime Token, Revival Jam, Marshmallon all have different defensive abilities. Slime Token is just as mortal as any other monster, Jam needs to regenerate (which can burn out), and Marsh is virtually unaffected.

Evil Natural Water did actually survive Saitama (although he was weakened); he was only killed when he was eaten, the punch didn't kill him.

I still think the Logias apply here; especially since Kizaru survived a point-blank nuke with no injuries; despite his 'guts' being scattered. 

I understand your argument, but I don't think it applies. OPM characters are designed to be defeat-able; including those with absurd healing factors or unusual defensive abilities.
