@mynekoheart In the previous chapter, the god of the world told Tsukina that because the other Savior hasn't been studying or practicing spells, she has no control of her magic. She's been leaking trance magic to the prince.
Also I really hope this causes the prince to open his eyes and see that the Savior is really a piece of shit.
How come nobody is strict with the prince? the bratty girl is kinda designed to make readers frustrated, I get that, but the the prince infatuated with her isn't the crown prince since he got an older bro right?
