He is the king who slays gods. He is the overlord who rules over all people. His words are the law of this world; you should fear his name, submit to him, pray to him, and praise him aloud. All people must remember: you should kneel before the demon king. In the endless world, Yuzuru Nozomi will eventually become the king of all heavens.

The transmigrator, Natsukawa Tiger, is 18 years old (?), mentally 30 years old (?), and his actual age is unknown. He is a young man who inherited the Holy Sword from King Arthur, a Star Sword Wielder with a body almost identical to that of Princess Arcueid of the True Ancestor, a candidate for Earth's Ultimate Origin, a well-known street hustler in the Clock Tower's parallel world, and a super-professional savior who has saved the world countless times! After saving the world yet again, he sincerely decided the following: [Even if Alaya and Gaia kneel down and beg me next time, I won't save the world!] [I want a vacation! I want to retire! I want to retire!] [Want me to save the world? No way!] Then, after getting married to his female brothers, only four years passed. Natsukawa Tiger, the human form of Arthur, the designated father of Alaya and Gaia, transmigrated again!

"Power over thousands of people? Supreme power? Inexhaustible wealth? Or is it to explore the truth of the world?"

"I... I long for breasts."

The first world is "God Killer"!
