I really liked the first episode of Boku Dake ga Inai Machi, reminded me of Steins Gate. Definitely number 1 for now.
Musaigen no Phantom World was pretty much a tropey harem anime but at least it has supernatural elements which I am always into supernatural.
Active Raid was meh, I'm into mech anime but if you like Tigger and Bunny you would probably like it. I was hoping for more of a Psycho-pass feel.
Ep 1 of Shoujo-tachi wa Kouya wo Mezasu was basically just set up for the anime so have to see episode 2, if it is like Saenai Hheroine no Sodatekata then I think it will be fine.
Not sure what to make of Norn9: Norn+Nonet ep 1 was just setting up the premise, reverse herem though?
