I've watched Parasyte several times already, its pretty good. Parasyte: Man gets an intelligent parasyte, who's goal was originally to take over his brain, instead takes over his right hand, the parasyte is intelligent and has insect-like morals, it can morph itself to take on weapon-like shapes to defend itself. There are other parasytes but most of them took control of the brain.
Ajin has an interesting plot but has zero fanservice and uses a lot of 3d cgi.
Ajin (Demihumans) are rare beings that cannot die, they look like normal people, once their presense is known, they are taken into custody government for their 'safety'. The main character discovers he's an Ajin and goes on the run.
Also check out some isekais. Most of the isekais are entertaining to watch even if the plot is dogshit.
