The Strongest Devil with a Gamer System: A high School DxD Story

Over the course of the first 5 years of his life, Sirzechs stuck to Mars like glue. It was his and Sirzechs 6th birthday party and the the other clans decided to visit as well. Lord and Lady Sitri and a 5 year old Serafall came over to greet the Gremorys.

Lord Sitri: "Hello Zeoticus and Venelana."

Zeoticus: "Hello Lord Sitri, Lady Sitri."

Venelana: "Boys, why dont you take Serafall somewhere and play?"

Mars: 'So, mother expects me to play with this brat that's currently looking at me like....you know what, I don't even want to know.' "fine. C'mon let's goover there in that corner."

Serafall: "I'm Serafall Sitri, what's your names?"

Sirzechs: "I'm Sirzechs and this is my older twin, Mars."

Mars: "Hi." 'So this is Serafall Sitri when she'syoung. I will pursue her when she's older...like much much older.'

As me, Sirzechsand Serafall talk we get to know one another better. One of the Younger Beelzebubs came over and introduced himself as Ajuka Beelzebub. He is an...interesting person.

Meanwhile with the Lord and Lady Sitri and Zeoticus and Venelana Gremory

Venelana: "So, what did you two want to talk about?"

Lady: "Theres movement on the Angel side. It appears they are moving closer to our territories"

Zeoticus: "So would now be a good time mention that the fallen angelsare moving closer as well?"

Lord Sitri: "If it comes to a war then I'm sure were sure to annihilate them."

Little did they know the the oldest child of Gremory Clan and Ajuka beelzebub heard this as well.

Mars: 'So, they're moving now, huh. I'll have to start training to prepare for the upcoming war then.'

As the Party came to a close Me, Sirzechs, Serafall, or should I say Sera since she insisted that i call her that, and Ajuka Beelzebub became great friends. All guests left the dinning hall and according to Mars, he had fun. Mars went to his room and told venus to open up his welcome gift that was in his inventory that he neglected for 6 years.

[Welcome Gift: Lightning Affinity, 5,000,000 points, A book all about Dragons and Dragon Slayer Magic, and 1x Weapon Gacha Ticket]

Mars: 'So let's see here Lightning Affinity, 5,000,000 points for the store, a book, and a Weapon Gacha Ticket. Interesting. Venus, apply the Lightning Affinity and use the Weapon Gacha Ticket.'

Venus: "Will do." Venus then applies the Affinity. A big slot machine appears and then the images start moving after awhile they land on the Image of a Great Sword from Skyrim called Bloodthorn.

Mars: 'While not one of the strongest swords from the game, it'll do. In my previous life when I visited the mortal world from time to time, one of things that I used to do to bypass time would be to watch what those Mortals called Anime and play Something called a video game.' He then opens up the Store.

Mars: 'Buy Shadow Clone Jutsu and the Dojutsu Rinnegan.' After that he tried it so he could start his training. "Ok here goes nothing. Shadow Clone Jutsu." After an identical Mars appeared he told him to lay in his bed and act like your asleep. After he left the room he slipped into the shadows and left the Gremory house. 'Now that I'm out let's try this. I.D. Create.' He soon found himself in a dimension filled with zombies. "Let's do this." Mars brought his Bloodthorn from his inventory and power slashedthe sword at a group of 5 zombies causing a red line come out of the sword and cutting the 5 zombies in half. Mars was about to move to the the next group but noticed something on the ground and picked them up.

50k points

Life Drain Skill

Mars: "Life Drain skill and points interesting." After 6 hours of cutting every zombie he sees in two, a massive zombie appears. "That is one big zombie, very well I welcome the challenge Mr. Zombie." A magic circle appears and 2 ribbons of power of Destruction came out and hit the zombie, hurting it. After noticing it got hurt he wanted to try something new so he formed a ball of pure power of Destruction energy and hurled it at the enemy. As soon as the ball of Destruction hit the zombie a massive dome of pure Destruction formed from the ball of Destruction. Once the dome disappears, he sees that the zombie is still standing but barely so he decided to end it. "That was awesome, but it's time end this. Destruction Gods Bellow" A 15ft wide beam of mana came out of his mouth, it was black with a red hue. "I think I used to much mana there. Oh well then, that just means more training to try to have more control. I see I leveled up a lot. Status."
