Dear Sister, I’ve Become a Blessed Maiden Vol. 3

THINGS GET COMPLICATED AS A “BLESSED MAIDEN” GROWS CLOSER AND CLOSER TO THE ARCHMAGE!
Umehiko and Theodorus finally connect as more than blessed maiden and archmage, but what are they? Don’t ask Umehiko; he couldn’t label them if he tried. Are they just friends? Friends with benefits? Or something more? As Umehiko struggles to figure out their relationship dynamic, he suddenly spots a very familiar girl in town—his beloved younger sister, Momo! When Umehiko learns that Momo, who he thought he’d successfully sent home, has been held captive here the whole time, he sets out to rescue her. But instead, Umehiko falls ill and needs Theo to rescue him!
Series Overview: What seems like an ordinary spring break evening for Umehiko and his little sister, Momo, quickly turns to confusion when a mysterious symbol appears in the sky. Next thing the siblings know, they’re in a strange world that’s definitely not their own. But Umehiko is only concerned with making sure his sister gets back home safely. Unfortunately, right as he sends her back into the magical seal, he’s pulled away and stranded in a whole new world! Theodorus, a powerful sorcerer who’s been working tirelessly to summon a blessed maiden, declares that Umehiko will become his spring for unlimited power and puts a strange symbol on the confused man’s body.
Suddenly, Umehiko is overcome with an uncontrollable lust—that only Theodorus can satisfy. Can he endure being the sorcerer’s new “blessed maiden,” or will he manage to find a way to escape?
