MTL - The Thrilling Sword - Chapter 1151 : Evil Space!

He is Monkey D. Luffy, but not the original Monkey D. Luffy, because in this world, that one is Lucy, his blood sister, while he had a peaceful childhood with his other three brothers. They all ended up following different paths since he didn’t have his memories. It was only when he entered a barrel lost at sea to save himself that he finally began to regain all the knowledge he had of this world from his past life. On top of that, he realized he could use this knowledge to his advantage to acquire everything he needed on his adventure. He was given four chances to summon people to start his journey, and more importantly, he finally received his two devil fruits, becoming powerful from the very beginning, with a plan that stretched to the end of his adventure.This story is the adventure of a man called Monkey D. Luffy, with the goal of becoming the emperor of all the seas in the world. For that, he will find the One Piece and destroy the World Government, for they cannot coexist. Be it the Marines, government agents, CP units, Tenryuubito, Holy Knights, Gorosei, or Im, Luffy will walk over a mountain of corpses.“I want you in my crew. Together, we will change the whole world and turn it upside down.”“Hahaha. Don’t worry, I believe in your potential, that's why I want you in my crew.”“My swordsman already fought you and lost. Now let’s see the strength of the world’s greatest swordsman too, right, Yamato? I hope you don’t mind fighting two rookies at once...?”“Awaken... Awaken my power... and destroy all your enemies...”“It’s good to see you after so long, Grandpa... and you, sister.”“Monkey D.? The most dangerous family in the world!”“Isn’t it a beautiful scene? Two Shichibukai and a Vice Admiral as my trophies! Come on, take a good picture and put it on tomorrow’s newspaper cover!”“I declare this kingdom my territory!”“Enel, you’re nothing but an idiot with a god complex. If you’re a god... then I’m a god slayer.”“As you said, Teach, people’s dreams never end! And if people’s dreams never end, why should I stop?”“Doflamingo... Jake... you’re so far from home. I hope you don’t regret this.”“You narcissistic woman, how can someone be so annoying and arrogant?”“What did you say, you damned man?!”“I now declare you husband and wife.”“It's time to return to the Blue Sea, after all, we have a world to shake.”“CP9? What a disappointment, Sengoku. I want money for them and Doflamingo... I want 2 billion berries at Enies Lobby in a few days.”“Enies Lobby was completely destroyed...?”“I've fought Mihawk, Jimbei, Crocodile, Doflamingo, Hancock, and Moria... you're the only one left, Kuma...”“It seems we've finally met, Rayleigh...”“Let's invade Impel Down!”“I came here to find you, sister, it's time for you to join my crew... Joygirl...”“It looks like we've finally arrived at the war.”“Sengoku... you tried to arm yourself to execute my brother, so I'll make an example of this Tenryuubito for the whole world.”“You can't do this...!”*BANG!*“He actually did it, that bastard....”“Your chains are loose, move your ass and get out of Marineford!!”“Saturn!!! I'M GOING TO KILL YOU!!”“I couldn't kill you last time, Akainu... but I'll make sure to do it now.”“Destroy the rest of Marineford.”“Let's get out of here. When you return, you'll take over this country for your family, Rebecca.”“No matter if we're on opposite sides... I will always love you, grandpa.”“It's time to start our training.”“Let's begin. Now, let's head to the New World, capture territories, and grow our fleet.”“Is the entire Straw Hat fleet ready? Now let's head to Wano, after all, we have a war against two Yonkou!”

Kai of the Sorcerer’s Tower is one of the last mages left, barely surviving in a world ruled by creatures of the dark — where the era of mages ended, and most of the lands got contaminated with dead mana. To save his world and fulfil his master’s last wish, he put himself through a forbidden ritual, risking his soul being ripped into pieces to make his way into the past. In an era with abundant mana — an era yet to enter the Golden Era of Magic. Things go wrong, of course, as they always do, and he finds himself thousands of years before the world fell to mana contamination — in the body of a young lord, Arzan. All is not well, though, as the young lord was murdered by someone right at the cusp of a beast wave threatening the territory, while larger threats loom on the horizon. There was a lot to do for Kai to regain his former strength in this time of primitive technology, but then again, he might just be able to change that.

When an era came to an end, various forces set foot in cultivation to compete for immortality. A young boy who spent most of the time sleeping got lucky in the troubled times and became an unparalleled immortal who could cover the sky with a snap of fingers. Was he going to live forever?

Being sucked into a fantasy world that nobody leaves doesn't sound half bad to Cain. He was a high school dropout with a drinking problem, living off disability due to his poor health, so it's not like he had much to lose except a few faithful friends he didn't talk to enough.

After a long night of drinking, Cain wakes up looking at what he believes to be the character creation screen of one of his beloved virtual reality games, but with no recollection of having purchased it. His unwitting choice to use the Random Character Creation option, unaware that the choice would be irreversible, sends him into this new world as a Puppet Master, a Summoning based class nobody else in the starting zone has ever heard of.

But as he soon realizes, this is no game, him and hundreds of others have been brought to another world with no instructions, no clear goals and no way home. It's a second chance to live a good life, but what will Cain be able to make of it?
