Well I am looking at the summer 2021 list...
Genjitsu Shugi Yuusha no Oukoku Saikenki is based off a light novel and I have read them... If the right team is making the anime, it could be really good!
100-MAN NO INOCHI NO UE NI ORE WA TATTEIRU 2ND SEASON is coming out. I am not 100% sure whether or not I like the first season, so I'll need to watch this to tell if it's legit lol
DEATTE 5-BYOU DE BATTLE sounds like Darwin's Game... But is it as dark? Who knows lol
TSUKI GA MICHIBIKU ISEKAI DOUCHUU. Hmm.... Sounds like the guy gets summoned, the Goddess says he is ugly and banishes him to the corner of the world... Not supposed to be comedic so it's hard to say if this one will be any good...
SEIREI GENSOUKI so memories of two people get put into one guy and by chance becomes a hero...
MEIKYUU BLACK COMPANY so he gets summoned like a hero, but forced into slavery instead... Could be legit... Lol
