The so called Gods
Logan moved the entire dragon into his dimension. Millions of people who lived on the dragon's body were already removed via chains left onto the forest nearby.
Logan's next target was the Moon Dragon god Selene.
Selene the moon dragon god lived alone on a mountain at the highest point was it could bath in the moonlight every night. Knowing the nature of her magic and the power she draws from the moon and the starts, Logan knowing astrology decided to attack in the morning time when both the sun and the moon aren't fully available not taking any chances and wanting to use the same strategize against Selene as the wooden dragon god, Logan covered the entire sky with the golden circles which chains upon chains descending onto the dragon who was sleeping, Chains covered the entire mountain not giving any opportunity to escape, the attack was completely silent not giving for dragon to wake up anyhow with Chains holding the entire dragon in his human form appeared onto top of the dragon's head which was struggling and inserted his hand inside the brain leading the black matter to directly entire the brain disintegrating everything inside and taking command over the body of the dragon, with two dragons under control, Logan moved to the guilt-ridden water dragon who have drowned an entire town.
The body of the Moon-god dragon was very unique with 4 blades like the scythe, due to it being sleeping and defeat in her sleep the full power was never used or the fight could have prolonged.
Putting the third dragon body back into the dimension, Logan moved to meet the water dragon god this time.
Mercphobia was living in with a girl around 11 years age, logan went up to his house and knocked on the door.
Mercphobia surprised by not being able to sense anything from the man standing in front of him: Who are you?
Logan: I'm here because of the 5 dragon gods, 3 are dead I will give you two choices first give me your powers second I will kill you and take your powers.
Mercphobia hearing the first part got surprised and by second part getting angry he truly felt sad by his act of drowning the village but he wanted to have his power to protect Karameel and the people of the village, he understood that the body standing in front of him was giving the choice out of kindness if what he said regarding three of the dragons fallen to be true.
Seeing the conflict on the face of Mercphobia, Logan decided to give him some time and told him that he will come back in the evening for the answer.
Soon evening came and Logan could see that Mercphobia with the convincing of Karameel and the villagers have decided to give up his powers but within his dimension, he saw the unwillingness in the eyes of Mercphobia. Remembering the lesson about greed before Logan came up the House while on full alert to avoid any surprise. Karameel opened the door and welcomed Logan inside.
Logan with fully activated EMS went in and found Mercphobia seating alone in the garden watching the sunlight.
Mercphobia turned to Logan and started to get up from his seat when suddenly the Karameel which have lead Logan in turned into water and trapped Logan. Mercphobia seeing his plan be successful rushed to deliver the killing blow in one go using his full power to do an energy blast. Logan already transported himself to another dimension using Kamui while also launching chains onto Mercphobia.
Mercphobia turned into his dragon form of the sea serpent, Golden circles covered his entire body as he was about to release of energy blast. Chains rolled around its entire body while piercing its tail with many weapons. Logan appeared onto of its head from the water bubble and tried to penetrate the head but it was too slippery, Using Devil's lover and God slayer magic of lighting element in full power Logan punched the top of the head making dragon wealing in pain while smashing its head into pieces. Leading the Black matter into the brain which did the same as before and took control over the body.
The body of the dragon was dragged into his dimension using the Chains, he could see the people of the village rushing up to him so Logan simply disappeared from the sport using Kamui leaving him with the last dragon Ignia which could give him flames to burn down the world.
Logan was in no hurry the guild master has dissolved the guild about 2 months ago while leaving his crystal to Laxus to take off. With about 8 months left, Logan in his dimension started to absorb all the powers of the dragon giving him 4 elemental dragon slayer magic, he has seen all the dragon slayers fight and knew about the basic techniques and such living in a quiet home he practiced everything for 4 months and then decided to move onto the last so-called god.
Ignia was special not only due to the nature of his flames but also his nature. While the other 4 were not of fighting nature and were simply living the life their way, Ignia was an angry immature brat who destroyed town cities as he wished, no one opposed him or try to take him on making him more arrogant and out of control. He was intelligent to a degree but most of the time underestimated his opponents in his arrogance.
Logan planned to take the fight with Ignia as a practice for his dragon slayer magic.
With the plan and all preparation done Logan moved to the decimated town in which Ignia lived. He let loose some of his magic to let Ignia know about his presence.
Ignia sensing a strong being coming toward his got all fired up and start to fly. Logan used the power of the wooden dragon and cleaned out the entire area for their fight while also bringing the water underneath on the surface. He chose night time to fight with Ignia to maximize the power outlet of Moon dragon god which depended on the moon and the stars.
Using his complete power, Logan started with a dragon breath covering the entire sky in golden color flames, Ignia also used dragon breath and overpowered Logan. Logan rushed to Ignia while using his EMS and appeared on its head and rooted a punch onto Ignia's head using Dragon's crushing fangs with the element of all 4 dragons mixed in.
Logan giving no time to Ignia used his water dragon god power and used Dragon's roar with the fullest power directly onto the head of Ignia, Ignia fell from the sky to the ground using his of Wooden dragon god and experience using wooden elements from the Naruto world created wooden dragon similar to first Hokage Jutsu which bit into Various parts of Ignia like his stomach while Logan powered up his Dragon's Roar with moon gods power and throw it onto the head of Ignia who got buried into the ground without the chance to fight back.
Ignia in anger broke off all the wooden dragons on its body and flew off into the sky while spitting into fire everywhere, Concentrating all his power into the pawn and punched Logan, Logan too charged up his hand using Dragon's Iron fist punched back with the power of 4 elements combining turning his hand into light red-purple while a white color light cover. Both punches collide throwing both of them back.
Logan recovered first and molded all 4 elements into Dragon god's Element Ball and throw it onto Ignia.
Ignia also recovered and saw a huge ball coming toward him and used his transformation magic and turned into Human and avoided the ball, Logan used Kamui and Appeared on the other side of the ball Holding the ball with both his hands and implanted it into Ignia which coved its entire body. Throwing him away miles away.
With everything that happened to his Ignia in his peak anger Roar fire destroying miles and miles of lands, Logan ran toward Ignia avoiding the ray of fire. Logan decided to use a little bit of God slayer magic Compressing both his hands and used Lightning God's Charged Particle Cannon, A dark pulse cannon passed through destroying the ray of fire from Ignia piercing its arm from the shoulder making it disabled it. Logan reached Ignia condensation a ball of water energy and shouted it into the shoulder injury. Ignia wailed in pain screamed and got thrown away.
Logan decided that the fight was enough, used chains which embedded into different parts of Ignia. Logan let the black matter from his arm covering it entirely while forming a Blade on it.
Logan used the blade onto Ignia lifting him in the air who was coved in chains even the mouth not giving any opportunity for attack. Started absorbing Ignia powers. Slowly the resistance from Ignia die down but chains still covered him entirely Logan not taking any risks waited for all the power to be absorbed. With only life force remaining Logan removed the chains from the mouth of Ignia.
Ignia with lifeless expression with no power even to stand lifted in the air via chains stood there, Logan smiled and started absorbing the life force out of Ignia who just stood hanged there without moving even a bit, he body got skinner and skinner his eyes lost all colors. Logan said in a low voice: Don't worry tell you, papa, I will be sending his other son Natsu soon to join you too.
And absorbed the last of life force completely.
