The main characters are also seen at a bathhouse

In one episode a girl's caretaker is said to take nudes of of her, and when the main character looks at them she tells the girl "You're hiding big melons" (in the sub) implying that she has bigger breasts than shown

One of the main premises of the story is that the main character can use her own blood from a cut on her hand to create a sword to fight demons/Youmu-s

Sometimes the main character becomes tired after using her blood to create a sword for a while so she lets go of it and her blood splatters the ground, it doesn't stay for long though since she sucks it back into her cut that it had already came out of, she then bandages the cut afterwards

nothing worse than damn and hell are used
