Shiroku is reincarnated into the world of slimes and acquires the unique skill [Traveler], which allows him to freely travel through other worlds.

Soharu, Reincarnated Spider, Dungeon & Fighter, Problem Child...

"Evil God D, I've tolerated you for a long time!"

With Shiroku on her back, Spider Girl Shiroori launched a gorgeous rebellion against a certain evil god D: "Shiroku, save me!!"

Artosh: "Sorry, I didn't let Lord Shiroku use his full strength."

Without even a moment of mourning for the God of War Artosh, the one who immediately rushed to the battlefield was the great will Caruso.

Shiroku: "Have you ever been defeated, Caruso?"

"How can I build a small garden with this **insect!"

Shiroyasha: "Come and help me, Shiroku, from now on, I will give you half of my beautiful girl."

"What?"

Storm Dragon Veldora: "I fight Shiroku?"

Start in the Great Forest of Jura and build a demon country from scratch.

Sakaguchi Hinata: "I tried so hard...

After traveling through the world of Demon High School and wandering around in it for a thousand years, when Chen Eliog became the fifth demon king of the underworld, he received an invitation from a dimensional chat girl.

Out of boredom, Chen Eliog chose [Accept].

Cang Yue: Welcome newcomer! I am the strongest fighter among all the girls, let me know!

Esdeath: The person above is talking nonsense! I am the strongest fighter among all the girls, let me know!

Yukinoshita Yukino: Hello newcomer! As an ordinary person, I am trembling between two big guys!

Shinomiya Kaguya: +1!

"…………"

Chen Eliog: "Thank you for the invitation! I am in hell and have just become a demon king: I have official business to attend to, so I will hide for the time being."

Having transmigrated into various anime worlds, Yu Sheng Qiuzhe obtains a god-level choice system. While walking the streets at night, he encounters a unconscious Rem, who is leaning against a corner. Out of a helpful spirit, he picks her up. Just then, a fierce shout comes from behind: "Let go of that girl!" "Ding! Master is about to face Tatsumaki's pursuit. Please choose!" "Option 1: Throw Rem at me! Decisively throw Rem at Tatsumaki while shouting 'Throw Rem at me!' Reward: 'Mystic Eyes of Death Perception!'" "Option 2: Kneel and beg for mercy! A true man can bend and stretch, knows when to advance and retreat! Reward: One bottle of Body Extension Potion (one-hour effect)!" "Option 3: Fight to the death! Never compromise or admit defeat until the very last moment! Reward: ..."

Transmigrating into the world of the "Hakoniwa" (Little Garden) in the world of crossover anime, Izayoi Sakamaki, while waiting for her invitation to the Little Garden, was invited to the Multiverse Chat Group and became its strongest member. Esdeath: "Izayoi, I will definitely not let you leave me too far behind!" Rikka Takanashi: "My contractor, following the ancient oath..." Nagatsuki: "You are hundreds of times stronger than the True Ancestor!!!" Touhou Project: "Um... Boss, do you have any extra Third Star Particles? Can I borrow some?" Gilgamesh: "I, the King, declare you the strongest!" Brunhilde: "Lord Izayoi, please save humanity!" Izayoi Sakamaki: "Thanks for the invitation, just arrived in the Little Garden, challenging the Celestial Theory." With her absolute power, Izayoi Sakamaki also became the chat group's sole administrator...

After traveling to the continent of Teyvat, I unexpectedly met General Thunder as soon as I arrived. But it doesn’t matter, she has the power of the God of Thunder, and I have the power of the Herrscher of Thunder!

General Thunder: "What kind of power is this? Why can you control the power of thunder that is more powerful than mine?"

Facing the incredulous look in General Lei Dian's eyes, Chen Ran smiled crookedly: "Can you be called the God of Thunder?"...

Lin En traveled through the world of Soman and was reincarnated as a half-blood demon.

Fortunately, the awakening system allows him to recruit his own demon family.

Not only can he reincarnate his family into special demons, but he can also give them an upgrade system similar to the grace of Jicuo.

So...

'Secretary Demon' Kasumigaoka Utaha: I understand everything!

'Psychic Demon' Yotsuya Miko: Evil spirits, retreat!

'Sword Demon' Busujima Saeko: Only killing is the most enjoyable!

'Food Demon' Nakiri Erina: God's Tongue, let me see your limit!

In addition, Lin En also has the 'Devil's Contract' that can cross the world.

"Little one, you've followed me all this way, and you're already so eager to become my disciple? You should know that I, the Palace Master, am usually very busy."

"But, I really want to become stronger, you big fox demon."

Looking at the child with white fox ears and tail in front of her, Yae no Miko smiled slightly. "Senior Fox Palace, you can't escape my grasp now."

"It's not impossible for me, Tsukasa, to teach you how to become stronger, but I don't want to be your master. The word 'master' makes me sound really old. From now on, you can call me Tsukasa-neechan."

"It's not impossible for me to teach you my skills, as long as you can persuade—no, convince—a shrine maiden to live at Narukami Shrine, and I'll teach you all my tricks."

Himeko Murata has a recent problem. She thought waking up to find her entire class transformed into Herrschers was absurd enough, but... why did she wake up to find her entire class of aliens, with not a single native Earth life form in sight?! The whole class has become aliens! Kiana from Nebula M78, Bronya from Krypton, and Raiden Mei from Galife. Faced with the students' new ancestral origins, St. Freya, the Far Eastern Demon Cave, has earned a new title: the Cosmic Demon Cave. Rumor has it that even Headmistress Theresa is ecstatic.

Ling Shu traveled through time and space, bringing the 'Genshin System' with him to the labyrinthine city of Orario. "Can I summon weapons and characters I draw in real life?" That's great. But... "Why do I have to choose a villain family to join at the start?" That's a real problem. PS: This is a fanfiction.

He's an orphan, abandoned by his parents and forced to work outside the orphanage to support himself. He's a 2.5-dimensional, pseudo-otaku. One day, a dramatic event takes his own life. He's chosen by a ruthless system to become its master, or simply the Lord God. From then on, he enters a different world, a different life, and a different experience. Embarking on a journey to become the Lord God—a girl? A daughter? A dimension?

It's all possible...

"Asuna! Yui took our panties again!!!"

"Mikoto...are these black ones...chickens?"

"Ram! You can't wash that dress! Rem! That's our sword, not trash!"

"Saeko-senpai, quickly grab Minami Rika and Shizuka-sensei, these two women are drunk again!!!"

"Hyori, Saten, Suguha... Damn it, blow her up!!!"

"Ikaros...can you give me this watermelon?"

"Uh... Tohka, um... it seems like there's nothing to cook... Hey hey hey, don't cry, don't cry, let's do it right away!!!"

“…”

However, it doesn't seem as serious as we imagined.

The system fainted in the toilet!
