Kaiju No. 8
Almost A-tier. But I think it's a bit too facepaced in the sense that although you do at least get to know the characters, it usually happens in the battle where they put a flashback. there isn't a "calm" period. It just keeps going.
I Used to be a Boss
Definitely a more in-depth MC. A monster who wants to know what it's like to be a human is given a human body by the system (unknown goals). The first season was about unraveling the mastermind behind a series of incidents. I don't think I like who they're setting up the main FL to be. I do and don't like the twist. But I think it adds complexity.
My Mom Entered a Contract Marriage
From the perspective of the child MC. But it's the mother who was given a second chance. she marries the emperor who is hinted to be a dragon and tries to balance her previous self who was a horrible mother to the her now.
Say Ah, the Golden Spoon is Entering
Fl is actually smart and resourceful. Has frustrations and not everything goes her way.
