Instant Death [DxD]

The next morning, Xander put a lot of things inside his Storage, he made sure to bring clothes that would last for 10 days. He took a shower and arrived at the school earlier than usual.

When he was at the entrance gate, he saw Tsubaki waiting for him. Sona already talked to Rias about them joining the Training Camp, Rias accepted but said that they would be far away from each other since it would hinder their growth when they're disturbed by something. Sona accepted the condition since she felt it was understandable.

"Good morning, Tsubaki-san!" Xander said while waving his hands towards Tsubaki. "Good morning, Xander-kun, Kaichou is waiting in the Student Council room" Tsubaki led Xander towards Sona. They chatted with Xander asking informations about Sona.

They arrived at the room and knocked thrice before the door was opened by Tsubasa. They went inside where Xander saw that everyone is ready, and he's the only one they're waiting for. "Uwah, you guys are to stiff, its still 30 minutes before the appointed time and you're already ready?" Xander said exaggeratedly gaining a annoyed looks from everyone.

"Now that everyone's here, let's go" Sona said as she used her magic circle to teleport everyone to the room of Occult Research Club. Xander just watched the process as his Menu skill rang.

['Sitri's Magic', skill acquired!]

Upon seeing this, Xander raised this skill upto lvl 7 gaining a power and mastery same as the Maou Serafall Leviathan mastery on her ice magic. 'This is really broken' Xander thought while sighing.

The next moment everyone was already in the Occult Research Club room and saw The Rias Peerage also ready waiting for them. "Sorry to keep you waiting Rias, someone came late" Sona said while glancing at Xander. "Ehh, don't be unreasonable Sona, I came early you know? Everyone was just too early" Xander said while pointing at them. Sona got offended by that and they started bickering again making Sona's peerage sigh.

"They're at it again" Tsubaki said as she turned towards Rias. "I apologize for my King's conduct, please wait for a few minutes, they would eventually stop" Tsubaki apologized to Rias for the trouble. "No, I'm quite happy seeing Sona like this, she's always serious and you can rarely see her get loose like this" Rias said while smiling at her friend.

After a few minutes, they finally stopped as Xander went to Issei's side, "I didn't introduce myself properly before right? I am Xander Ranvil, a human, nice to meet you Sekiryuutei" Xander said while raising his hand to offer handshake. "Ah, my name is Hyoudou Issei, Buchou's pawn and let's get along!" Issei accepted Xander's handshake and they smiled at each other (no homo)

Everyone walked to the mountain where they carried a huge bags on their own only Xander didn't carry anything since the storage was quite handy. They arrived at Rias's mansion while Issei is panting, the parted ways and the Sona Peerage went to Sona's mansion on the other side of the mountain.

After placing their things inside the mansion, they immediately started training. Xander started thinking about a certain manga where the protagonist is a overpowered baldy. He visualized the martials arts of a certain someone who rise into the top using this Martials Arts, he can parry any attacks given to him because of that martial arts, it is said that it's the strongest defensive martial arts in that world.

['Water Stream Rock Smashing Fist' skill acquired!]

Xander raised it to level 5 reaching bang's level, above that would evolve the technique just like what happened to Garou, though she would need to combine more martial arts to do that. He first taught Tsubasa Yura, she's a talented martial artist so Xander hope that she would gain this skill. After 5 minutes of trying to teach Tsubasa he gained another skill.

['Teaching' skill acquired!]

Xander then realize that he can pass skill to other easily using this skill, so he raised it to level 7 and abused it. Using this skill, Tsubasa learned the Martial Arts in a mere 5 hours, making her the strongest in the peerage surpassing even Sona. The only weakness of Tsubasa has is 'Experience' you can't give experience by teaching so she need to gain it herself. Don't ask why she learned it in mere 5 hours, nobody understand DxD's logic, Issei can even go toe to toe with Gods in a mere half a year.

Next is Momo Hanakai, she is a bishop so her magic talent is above the average. 'Shall I raise her to become someone like Maple?' Xander give it a thought and kicked the thought out of his head, he immediately started training her, his goal for her is to make her the strongest barrier mage. Strong enough to at least shield against a Maou.

['Barrier' skill acquired!]

Xander used the Teaching skill again and taught Momo anything he know about Barrier, and she learned the skill in just 2 hours, 'Bishop piece's enhancement are really good' thought Xander while proceeding to the next person.

The third one he taught was Kusaka Reya, she is also a bishop and was taught by her grandmother at a young age, so her proficiency is much higher than Momo, she best at communication and spying so, Xander learned a Clairvoyance skill (Merlin), the ability to know anything about the world in the present. And taught it to her, though since she just learned it, her range is just 50 meters. He also taught them the 'Endurance' skill. Comparing Sona's peerage to a fortress is already acceptable. Reya is now the information gatherer in their group.

Next is Tomoe Meguri, a Knight from Sitri's Peerage. She is a expert Swordswoman so Xander plan to turn her into a Master Swordswoman who can cut anything with just her finger.

['Sword Mastery' skill acquired!]

Xander raised it to level 7, in this level Xander feel that he can cut the whole world in half with just a slash. Maybe at level 8 he can cut concept itself. Xander won't raise it at that level, that would be overkill, Gods would immediately cry if they know that.

Xander taught Tomoe until she finally obtained the skill, making her a powerhouse among the young devils.

Next is Tsubaki Shinra. The peerage's queen and a user of Naginata, she is only second to Sona in terms of strength. "You can do anything with devil magic right?" Xander asked Tsubaki not sure about this fact. "Yes? Devil Magic is quite versatile since you can form it with anything just use using the imagination of a person" Tsubaki explained while Xander grinned.

['Quake' skill acquired!]

['Naginata Mastery' skill acquired!]

After 3 hours, Xander turned Tsubaki into Whitebeard, he taught Tsubaki using his Teaching skill, resulting her mastery towards Naginata growing and he also taught her how to visualize her magic to become something like a Gura Gura no Mi. Now Tsubaki's main ability is to use her Naginata and break things with her Quake ability.

And lastly, he made taught Sona until she learned how to use her magic more creatively. Like using her magic to make the water inside the body of a person burst, resulting the enemy exploding like balloon, her magic became so strong that the weather would change based on her mood. He also made her learn the 'Absorb' skill so that once her water touched the enemy it would absorb everything that Sona wanted to. Sona can control the rain and add some effects to it, like petrification which is a good AOE magic. Overall, Sona gained her place in the Peerage again, she became stronger than anyone else.

After 5 days of training, everyone's power became so strong that they are already Ultimate Class Devils, they were shocked by their own growth, at the 4th day, they became arrogant with their new strength so Xander had to lecture them until they finally regained their sense. They apologized and was ashamed by their conduct so they asked Sona to punish them which she did, though Xander didn't know what she did to them since when they came back everyone was pale and had a frightened expression.

They already left Rias's Peerage behind without their knowledge, though they were wondering why they always hear an explosion near their place. Sona's Peerage was grateful towards Xander for making them this overpowered, they would always just be side character if they didn't get this power up.

Sona's feelings for Xander was already high even before they started this training camp, and now that he made her entire peerage reach high level in just five days, she couldn't deny it anymore, in the night of the fourth day, Sona and Xander played chess where Sona lost miserably and in the next morning Sona finally announced that Xander is her fiancee, though the Sitri clan still has no knowledge about this, if they did then a wild magical girl would really arrive in the mansion.
