Reincarnated as the Piggy Duke: This Time I'm Gonna Tell Her How I Feel! Volume 7

A rift runs deep between mother and daughter—not just any mother and daughter, but the queen and crown princess of Daryth. The queen has taken the first steps towards Princess Carina’s ascension to the throne by staging a ceremony at Kirsch Mage Institute, but behind the pomp and circumstance lurks a heartless plan to gamble with Carina’s life. The queen means to use the young princess as bait to lure the witch out of hiding. Carina, meanwhile, can only grin and put on a brave face for her country. The fate of the nation rests on the bridging of this rift—how could Slowe possibly in good conscience sit idly by? Slowe intends to intervene by wreaking havoc on everyone’s plans. After all, he has nothing left to fear...for he’s the invincible hero who finally manages to confess to his beloved retainer!
