Seen a lot of Bocchi comparisons which I understand, but I'm seeing Watanare with this group dynamic.
The MC is Renako who failed to make her HS debut pretending to be a popular extrovert.
The vampire is Mai with her high level charm, but she's not rich or as unbearable.
The simp is Kaho. An easy one to one comparison.
The exorcist is Ajisai when interacting with the MC and is Satsuki when interacting with the vampire.
It's shaping up to be a fun little gag manga but I wonder if there's too much going on with the whole school being full of various types of semi humans.
