Thanks for the chapter!!!!
Alongside the mystery what I really love in this manga is the friendship part, it's not the shonen friendship will resolve everything but a more mature one which make betrayals more hurtful each time
now hopefully they will talk to Minami. if they talk to the princess the mastermind won't have anything again Nanaura anymore.
Edit: actually I always wonder what would they do if they found the traitor? they can't juge him for his past sins, the mastermind can't be juge by our laws (they can't just bring him to the police) . As long as Zeze don't use the forbidden magic everything should be fine right ?
