Dark Prince Rises by Ronin2106

Chapter 16

Henry's wand swiftly made an intricate pattern in the air, projecting a Protego Diabolica around his himself, with dark flames destroying the wave of dark crimson magical energy that Rias had sent agaisnt him. He let himself a quick breath of air, while he mentally called upon Irene for the fourth time. And just like three times before, she didn't respond to his summon, making him groan and mentally curse her very name and existence in hearts. She was supposed to be the main protector of House Le Fay, and now the very House she was supposed to be protecting was in danger of being destroyed. And she wasn't here to protect it!

Less than half a minute after her initial attack failed, Rias' magic flowed out of her hand once more. The dark flames once more met with Rias' magic, but this time, Henry's most powerful shield had cracked under the sheer might of half-Devil Le Fay. Crimson energy rushed towards him, and had Henry's instincts not been honed through training with Irene prior, he wouldn't have been able to apparate out of the spot, before it got demolished by the destructive magic. Rias' eyes widened slightly when she saw that she hit nothing but dirt and ground, before she started to look for her prey.

"Fulgur Maxima!" Rias' ears heard a shout from behind her, followed the very next second by an immensely powerful blue lightning striking her.

Henry channeled his magical power through his wand, sending one his most powerful spells at Rias. He had wished that the Le Fay witch would fall from this attack, but he was wrong, as he saw a familiar crimson aura surround her form and protect her. He saw that she was channeling most of her power into the defense, and that Henry was actually straining her with his attack. Knowing that his own magical reserves may not be enough, Prince Le Fay called upon the magic of his land, letting it flow through his form and empower him. With a roar, he unleashed that stored up energy at Rias, enhancing his lightning and breaking her barrier. Her body was struck the next second, sending her flying away from him and into the ground.

Breaking off his magical spell, Henry nearly stumbled back, but had managed to stabilize him from falling down. Casting a quick glance at the lying form of Rias, he saw that she had lost conciseness, but wasn't too hurt, with only a few slight burns and burnt up clothing on her. Her barrier had managed to withstand the majority of power, and so it had saved her life, as she was only hit by minimal power from his Fulgur Maxima. Still, at least he had managed to knock her out, giving him the needed opportunity to collect his thoughts and take a breather.

Henry's mind immediately began to analyze what Rias had told him earlier, trying to figure out how was she here. She had claimed to be the daughter of Artorius Le Fay and Irene, with former being his predecessor as Prince Le Fay, according to the records of Le Fay House. Those same records did state that Artorius was married to a member of House Ravenclaw and had children with her, but all of them were killed, and there were no records about Rias and Irene being a wife of Artorius. That could mean that either record were tempered with, possibly by Irene herself, or that it wasn't common knowledge of Irene and Artorius' relationship, and that Rias was born out of wedlock and officially made Le Fay later.

Either way, Henry was completely certain that Rias had the magic of House Le Fay in her, as well as demonic powers of her mother, Irene Belserion. Thanks to a special training room, inside which time ran slower than in real life, Henry had the opportunity to train with Irene, to get more powerful and practice new and powerful ways of magic, and through those training sessions, he had memorized the magical signature of Irene. That same signature was present on Rias, which did confirm to Henry that Rias was indeed daughter of Irene. However there was still the elephant in the room that required solving:
