Hollow Regalia. 3

When Iroha's channel surpasses a million views overnight, Yahiro and the others know the reason can't be anything good. As it turns out, a sleuthstreamer called Yamadou has exposed her as a dragon medium on his channel, and now the whole world is watching Iroha's every move! Before Yahiro and Galerie Berith can do anything to retaliate, the Guild detains Yahiro…as a suspect for a rash of murders?! While Yahiro is away, the Galerie's Japanese branch comes under attack by a foe with an old grudge. And with more Lazaruses appearing to shake things up, Iroha and her siblings may be in more danger than ever.
