This is a fanfiction of Rimuru and a pseudo-fanfiction of Ainz Ooal Gown. Lin Ming, possessing the Nazarick Great Tomb system, is summoned by people from another world. In Rimuru's world, he summons Albedo, Demiurge, and others one by one, and establishes a dynasty two years ahead of schedule in the eastern part of the Jura Forest. When Rimuru establishes the Demon Kingdom Federation in the western part of the forest, he discovers that his older brother is actually incredibly powerful. Thus, the story of the older brother and his younger sister... no, his younger brother, begins! What kind of interesting stories will unfold when two Demiurges appear at the same time? What strange sparks will fly between Shalltear and Luminas, both true vampires? The early part of the story is a slow-paced, hellish development for the protagonist, so please be patient.

(Not a crossover anime/manga universe, but set in the Akatsuki/Akame ga Kill! universe) "Ichijo, I bestow upon you the Imperial Arm Murasame to commemorate your achievements." "No, too much killing intent, it will harm my health." "What about the Demon Possession?" "No, Lancer's luck is E, how many masters has this thing killed?" "Gaia Foundation?" "I don't want to be a cross-dresser!" "Then what do you want? Tell me, and I will grant it to you." "I want the Demon God Manifestation!" "But, this Imperial Arm is on Esdeath, if you want it, wouldn't you be taking Esdeath home with you?" "Your Majesty is wise, I thank Your Majesty for the marriage!"

The world has inexplicably changed; Mai Sakurajima, Misaki Shokuhou, and Misaka Mikoto suddenly appear. Why can he still connect to another world? The Holy Grail War; the Apocalypse Virus; the labyrinth city of Orario; the Teigu users; "The world is so chaotic, since I've become a demon, I should be cunning, cruel, and tyrannical, that's how it should be..." But these girls before him are not only not afraid of him, but their faces light up with joy upon seeing him; the demon falls into deep thought...

Using the Impure World Reincarnation technique, he was unexpectedly reincarnated into the world of One Piece, becoming the son of Dragon and given the name Luffy. Although the name is the same, his core has changed, and thus his path is different. He initially intended to skip the Devil Fruit and join the Navy, but after unexpectedly encountering the red-and-white-haired princess, he discovered how unfamiliar the world was. How can this be a movie world? How could my King Luffy possibly have a childhood friend and a romantic comedy?

Transmigrating to the ninja world, I awaken a strategy and development system, but as my strength grows, why does it feel increasingly chilly behind my back?

"You're saying I'm special, right?"

"Senior, you gave me hope to live. I will never let you leave again."

"Chenye-kun, let's leave Konoha and go back to the life we ​​had back then, okay?"

Chen Ye: Speak properly, put the knife down first...
