Assessing The Situation

When Soren saw that Grayfia stopped attacking Serafall, and then saw the other strong devil, who he assumed was Euclid, sneaking behind Serafall, Soren thought:

'If my Magic Eyes is working the same as in the YGGDRASIL, then this should work too...' he thought, and immediately two black dragon wings emerged out of his back. Then, he tried to fly like he used to in YGGDRASIL, and it worked the same, so he flew at full speed, just in time to block the spell Euclid shot at Serafall.

"Who the hell are you!?" shouted Euclid in anger

'I'll just act like I used to act in YGGDRASIL' Soren thought, before answering:

"Don't shout at me, devil, for I'm the Dragon Emperor, The Dragon of Gravity and Void, Soren!"

When he saw Euclid looking at him with a doubtful expression, he thought:

'When I said that in YGGDRASIL, players used to run away immediately... As expected, it won't be as easy here...'

"The Dragon Emperor? You must be joking! There are only two dragon emperors in this world: The Red Dragon Emperor, and The White Dragon Emperor! Even if you're a dragon, you're a fool for comparing yourself to them!" said Euclid, and started to prepare another spell

"Then, I shall show you my power, and you'll bow to me in fear!" said Soren, raised his hand, while laying his other hand on Serafall's shoulder, and said:

[Greater Gravity Manipulation]

Greater Gravity Manipulation is a 9th Tier spell in YGGDRASIL, which allows the user to increase or decrease the gravity at his will, in a certain space, depends on the user's power.

Upon casting the spell, a giant magic circle appeared under all of the battlefield, and immediately all of the devils, including Euclid and Grafiya, were sent crashing down to the floor, as an invisible powerful pressure crushed them into the floor continuously. The only ones who weren't affected by it were Soren and Serafall.

"What... is...going...on?" asked Euclid, barely able to speak

"This is my power. I've increased the gravity in here, causing you to get down to the floor, like the vermin you are" said Soren as he started to descend, when he suddenly felt a little tired and dizzy

'I feel like half of my energy disappeared... what is this feeling?' Soren thought, but decided to ignore it, and looked down.

He saw Euclid looking at him with shock in his eyes, and even Grayfia showed her shock on her face. He bent over, so his face was in front of Euclid's face, and said:

"You have messed with the wrong person. Now it's time for your punishment" Soren said, and then stood straight, raised his hand, and said:

[Black Hole]

Black Hole was a 7th tier spell, which opens a black hole that sucks all of the ones that the user considers as an enemy into an artificial space.

Upon casting the spell, the Greater Gravity Manipulation was canceled, but a black hole appeared at the middle of the Old Satan Faction's army, sucking all of it inside, leaving only Grayfia alone in the battlefield

"What was that!?" asked a voice from above, and Soren looked up, and saw Sirzechs coming towards them with more devils

'Good. Now I can finally-' Soren started to think, but suddenly his eyesight became blurry, and he felt the dizziness intensifying

"How did you do that??" asked Serafall as she turned to face him, only to see Soren slowly falling down

---- Time Skip ----

Soren groaned as he opened his eyes, and saw an unfamiliar ceiling

'What happened? Was it really a dream?' he thought, as he sat up

Then, he felt something on his thigh and looked down, and saw Serafall sleeping on a chair, with her head laid on his thigh

'I guess not... but what happened to me? The last thing I remember is that I used [Black Hole] and then felt dizzy... Now that I think about it, it started after I used [Greater Gravity Manipulation]...' he thought, and then he realized:

'My MP ran out! That's why I fainted! My MP ran out because I used 2 high tier spells one after another. But it's weird since my MP doesn't suppose to run out after using only 2 high tier spells... oh right, I did one last raid before the shutdown, so my MP hasn't been restored yet...

I treated the battle as in the game, where when you ran out of MP, you simply can't use magic anymore. I don't know how, but I somehow in the Highschool DxD now, and I'm not in a game anymore, so when you use all of your MP, it has consequences!

No, can I really call it MP from now on? It's not a game anymore...

No, it's not something I'm supposed to worry about right now. The main thing I need to figure out is how did I get here, and if there is a way back.

As much as I love the series, the world where it happens is fucked up! I don't want to spend my life in a world where there are beings, like the Great Red and Trihexa, that can destroy the world in a matter of seconds if they only wished to!

A world where there are messed up people like Rizevim! I want to return to my home, where I have a decent life, with a solid salary! My home, where there aren't any life-risking events happening daily!!!

...No, I can't panic right now. I have to think rationally. I can't expect the solution to appear by itself. I'll have to at least settle down in one place, where I can research properly. Now, what do I do about this?' Soren thought and looked at Serafall's sleeping face

'Cute...'

As if feeling his gaze on her, Serafall slowly opened her eyes and met his gaze. Then, her eyes widen, and she quickly stood up, bent towards him, grabbed his hand with both of her hands, and looked at him with worry in her eyes

"Are you okay??? You used too much of your magic and fainted!"

'Do not blush! You need to keep up your act, else you'll be treated like someone who can be controlled! I don't want devils to annoy me, and ask me to join their peerages all the time!!' Soren thought and averted his gaze, so he won't be able to look at the generous cleavage she was showing by bending towards him and said:

"Of course I'm okay. Something like that is trivial for me"

"I'm glad..." said Serafall, and closed her eyes, as she pulled his hand into her chest unconsciously.

Soren's eyes widen in surprise, as he felt the warmth and softness of her chest against his hand, and was using all of his will not to blush, and pulled his hand away

"Where am I?" Soren asked

"You're in a medical facility owned by the Sitri clan. I brought you here after you fainted" Serafall said as she sat back on the chair

"What happened after Sirzechs Lucifer arrived?"

"Sirzechs Lucifer? Who are you talking about? Sirzechs last name is Gremory" Serafall said with a puzzled expression

Soren's eyes widen, as he realized his mistake

'I forgot! Sirzechs, Serafall, and the other devil kings became the devil kings only after the civil war ended! It means that they're still using their original last names right now!'

"You're right. Looks like I'm a little confused, as I only woke up now"

"Are you sure you're okay? Do you want me to call the medic?" asked Serafall, the worry returns to her eyes

"I'm fine. You don't have to worry about me"

"...I think that I'll call the medic anyway. Just to make sure you're okay" Serafall said, stood up, and started to walk towards the door

"Why do you care so much? We just met" Soren said

"Because it happened to you because of me. It's my responsibility to make sure you're okay" Serafall said and smiled brightly at him, and then walked out of the room, closing the door behind her

'...That was too cute...'
