Yuuji Sakai, the usually vacant and somewhat weak protagonist, lives an ordinary life until the sudden appearance of a monster disrupts his ordinary life. Under the setting sun, Yuuji is suddenly attacked by an alien monster that transforms human "existence" into spiritual fire and then devours it.

At this time, a girl who called herself "Flame-haired and Burning-eyed Slayer" appeared and rescued Yuuji from the monster's mouth. Yuuji Sakai named her Shana based on the name of her large sword.

She told Yuji that his life was about to end - it turned out that outside this world, there was another world called the "Red World". In order to realize their ambitions, the people there took away the world's original power, the "power of existence", from humans one after another, and Yuji was one of the victims.

After the Crimson Apostle took away the "Power of Existence",...

He traveled to the world of the powerful Shadow Master and originally wanted to replace Shadow and become the master of the Shadow Courtyard.

But Shadow's strength was too abnormal, so he had to settle for second place and become the second in command of Shadow Courtyard.

Lin Nan, a dead otaku, downloaded an APP called the second dimension, and was able to communicate with various second dimension characters. He learned Kamehameha from Sun Wukong, learned to make high-tech armor from Iron Man, Conan taught him detective skills, Uzumaki Naruto taught him ninjutsu, and Luffy's fruit shop opened to sell various devil fruits.

Inadvertently, he also had a love affair with the Sailor Moons!

With the entire second dimension behind him, there are endless possibilities!

In the endless world, a strange legend circulates: in a special little shop, by signing a contract with the shopkeeper, one can obtain everything they desire—powerful strength, countless riches, and knowledge from another world! But few know that this shop also possesses the power to change destiny, whether past, present, or future, or regardless of race or identity. When they are willing to gamble everything to change their fate, the door to this shop will open for them, and a new destiny will be born here! "Sign a contract with me, and then—transcend destiny!!" — Meanwhile, the shopkeeper, Lan Xing, is looking helplessly at his ever-growing deficit in his account book. He doesn't know when it started, but the number of girls in the shop seems to be increasing: twin oni maids, an elf girl who loves dolls, a cat-eared blade that transforms into a sword… 'The meal expenses have gone up again this month.' He only initially wanted to reciprocate a gentleman's kindness… (Also known as the Dimensional Aid Exchange, Dimensional Oddity Store, Dimensional Exchange…)
