As the result, Hiroto was "punished" by Torlan as the latter sabotaging Solum's chances of improvement, such as expelling Solum students from studying at Secondaria Cathedral.

As the result of Joachim's imprisonment, Felkina was spared from execution but she was barred from meeting Joachim as her ramifications for joining his rebellion, though her one-sided grudge against Hiroto never ceased. During his feud with Magia in Volume 13, Hiroto treid to contract with Felkina with numerous letters but she ignored them all due to her one-sided hatred for him despite his mercy for her and Joachim their defeat. Its only after hearing news about the pincer attacks from both Magia and Phyllis-as well as Belffergo's plot in reducing the vampire's prowess through a probation against them-forcing Felkina to (reluctantly and unintentionally) help Hiroto by not only revoking the probation just one day after she "approved" it, she also informs him about the sinister plots of Belffergo and Rasmus. Even after his victory, Felkina refused to acknowledge Hiroto until Moldius spares her and allowed Joachim to visit her under Hiroto's request, of which the king fulfilled it as his reward to the Difrente for his heroic deeds in saving Lusina.
