The way Klaus laughs at the sight of sunlight despite him clearly trying to avoid it leaves both Shadya and Irina confused.
They cannot understand that because they are unaware of how the Dragon Princess's blood can 'avoid' his only real weakness.
But while the fairy is only concerned, the necromancer sees an opportunity in that. Then she quickly gets up and faces Klaus with a curious expression. "You don't like sunlight, do you?"
Even looking at Shadya in that bright sunlight is hard for him as it hurts his eyes. "It can't stop me from killing you."
"Shh..." Shadya sighs as she continues to stare at him. "It's normal for a dark creature like you to hate the light; that's the same for me... but I bet the fairy loves the light."
[???] Klaus feels his instincts being activated to the maximum at hearing those words; he knows that Irina is in danger and tries to run to her as quickly as possible.
*BOOOM*
But Shadya acts faster, causing her black hands to break another piece of the outer wall, making beams of sunlight reach Klaus, momentarily blinding him.
[SHIT!!!] That sunlight is very bright, and after so many years in darkness, he is very affected by it.
Even his other senses are shaken, and he gets paralyzed for a few seconds.
That while is enough time for Shadya to create more black hands around Irina's body and trap the fairy, who tries to fight back but cannot escape.
Klaus quickly recovers and tries to get to Irina, avoiding the light, but Shadya breaks more walls to slow him down while having the black hand take the fairy outside the building.
"NO!!!" He tries to advance outside, but the sunlight forces him to retreat; even with the Dragon Princess's blood in his veins, that light still reduces his powers and damages his body.
Shadya keeps the black hand holding Irina in the air as she looks at Klaus. "I said that I'm willing to let this damn fairy live if you stop resisting me, but... if you leave me no choice, I'll kill her now."
Klaus remembers the pain he felt when he saw Irina suffer and he couldn't do anything; he can't let her get hurt again; he can't let that never happen again.
He only has one trump card, and he wanted to keep that until there was no other choice, and now he has no other option, so without thinking twice, he shoves his hand into his own chest.
"WHAT!?!?"
"NOOO!!!"
Shadya and Irina are shocked when they see Klaus's black blood splashing over his torn clothes; they have no idea what he's doing, but it's excruciating for them to see the man they love get hurt.
Klaus wastes no time and uses his fingers to open a way into his heart, pushing his other organs to the side.
That is very painful, but he doesn't stop until his heart can be seen even by the girls, and it is a mix of a normal heart with crimson spikes that come from inside the organ.
Before Shadya and Irina can say anything, Klaus quickly takes the bottle of blood from his storage ring with his other hand and brings it to his heart.
Then, shocking the girls to their core, he smashes that bottle against his heart, destroying his most important organ and splashing blood inside his chest.
With that act, he not only destroyed his heart but, more importantly, he destroyed his blood essence's reserve, causing that powerful concentrated blood to spread through his body along with the Dragon Princess's blood.
That is one of his vampiric tricks, one of the most dangerous, which makes him consume all the power of his victims' blood and use it to boost his strength to the maximum; however, that effect is temporary, of course.
Klaus had done it before when he faced powerful Witches on Earth, but now, with the addition of the Dragon Princess's blood in his body, he doesn't know what will happen next.
At first, he feels a lot of power running through his veins along with that mixture of blood and blood essence, but soon after, his body begins to change, and that pain from before reappears even stronger.
He clenches his teeth to contain the pain, but scales appear over various parts of his skin, and the bones in his back break and rip his flesh from the inside out. "AAAAAH!!!"
"KLAUS?!?!" Shadya and Irina are both very worried.
But he's confident that change can't be a bad thing, and even the intense pain in his back makes some sense when his bones open big holes in the back of his shoulders, where they come out, creating two bloody wings.
The scales over its skin are dark red, similar to the Dragon Princess but also different, as well as his wings are not exactly like the Dragon race.
Klaus continues to feel a lot of pain as his wings keep growing, almost touching the ground with their sharp points; His wings are sinister in style with sharp, deadly spikes throughout as well as dark crimson hard flesh.
And even though he never had wings before, he felt as if they were already in his body from the very beginning; That's an intuitive feeling, and just slightly flapping them is enough to propel his body into the air toward Irina.
*WHOOSH*
Klaus feels freer than ever while he's in the air; not only can he fly now, but the sunlight has almost no effect on his body, especially the parts covered in scales.
But he doesn't waste time enjoying those new sensations and instead focuses on Irina. His speed is very high, and he gets to the fairy's side before Shadya can react and then frees his beloved by destroying that black hand.
Irina is so shocked by that, but her body instinctively feels good when he hugs her. "Klaus..."
"It's okay now..." He smiles at her and kisses her forehead.
Shadya is also shocked as she watches Klaus stand in midair, flapping those frighteningly beautiful wings. "You canceled your weakness using the Dragon's blood... I had no idea Ann saved some of that."
Klaus looks directly into the sun for the first time after becoming a vampire. "I told you not even the sun could stop me from killing you."
