Today the protagonist is helping Chizu clear her temples, with Kirara also helping with the cleaning. Something seems off—he received a mission from Asuka days ago to take care of two Demon-Hybrid sisters, Sofie and Yufie, and they're not at the temple. The wise action would be to search for the girls, who are probably making trouble. Sofie and Yufie are devils in every sense. When searching for the Demon sisters, he suddenly hears a loud explosion coming from Gosha Academy. He obviously rushes to see what happened—maybe it involves Sofie and Yufie. No, it's obvious these girls are involved. Arriving at Gosha Academy, he finds a wall destroyed and from a distance can see a tall, well-endowed woman with dark-blue hair carrying Sofie and Yufie by their collars. The tall woman is Rin Uehara, a Taimanin Teacher. Sofie is cursing Rin loudly. "Hey hag, release us! We already said 'sorry' for what we did! Release us, damnit!" Yufie sighs with her usual bored voice. "Hey sis, calling a teacher 'hag' already messed up our entire situation. Shut your mouth." The protagonist approaches Rin, who notices his presence and throws the girls into his arms. "Oh, look who's here—the 'golden-boy' of Asagi and Shiranui. These brats are your responsibility?" Rin says while pointing to Sofie and Yufie, then continues. "Because they just exploded an entire classroom. Better watch these damn brats." The protagonist is confused about what's happening as Rin comes closer, speaking with a very scary tone. "Also, keep these girls far away from my cousin. They're a bad influence. Shiranosuke is learning all sorts of things because of them. Take responsibility, or I'll punish not just the girls, but you too. Do you hear me?" Rin then grabs his shoulder and squeezes with enough strength to almost break it, showing she's completely serious about her words. Rin is not joking.
