My name is Ammons, and I'm a villain. I can modify common sense and exchange various villainous abilities through the Demon King System to create my own Demon King powers. Reincarnated from ancient times into a useless prince, this holy mage protagonist's magic is unmatched, but your fiancée is too shy~ Your master is very charming~ And there's the genius prodigy from the Duke's family, born invincible, and your sword saint maid is very alluring! What, you're actually a little loli? Well, I'll take you all! Those reincarnated old men, overpowered protagonists, heroes, etc., with me, Ammons, you'll all suffer!

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…)

I've been transported to the Dragon Ball world as Blue General! Right from the start, I'm facing Tao Pai Pai's tongue-twisting attack!

The system's disappearance negated the power of the plot. In the future Dragon Ball world, Blue General will be the protagonist!

What can General Lan, with a combat strength of over 200, do in the city? He can raid gangs! Kidnap generals! Throw away kings! He can do whatever he wants in the city! But in the distant universe, because of the protagonist's fluttering butterfly wings, a spaceship speeds towards Earth!
