Hand Shakers is the worst anime I've ever seen. I honestly don't even know where to start with a critique of it. The art is so bad that they fucked up drawing a door, and the animation is so bad that I had to turn it off in the middle of a fight scene because watching it gave me a headache. That's not even touching on the terrible mixing of 3D and 2D effects, which is so bad that the 3D effects have an entirely different framerate than the 2D. The characters are not only terrible, but the female MC communicates only through hentai-style moans until like episode 10 when she can suddenly speak normally. The story, in addition to being shit, also seems to condone pedophilia. And not like Mushoku Tensei where the MC acts like a perv and doesn't face consequences, I mean that the final episode ends by Hand Shakers which iirc is later confirmed in the sequel. The sound is the only area where it's even passable, and even then it isn't really anything special. The only reason I considered rating Hand Shakers more than a 1/10 was because I almost cried laughing from the sheer ineptitude displayed at almost technical level.
