In a Honkai reactor laboratory at Schicksal headquarters, Himeko Murata faced an unprecedented predicament, with two S-rank Valkyries blocking her path. Just as she was in despair, Himeko's intense desire to save her students resonated with an unknown entity. 【Hello? Are you in trouble? Do you need a hero to save you?】 "What...is this?" 【If needed, please place an order with Dimensional Odd Jobs Shop. Our shopkeeper can do anything!】 "Please help save Kiana! Please! I'm willing to pay any price!!" 【Request received】【Request details: Save Kiana】【Reward: Everything Himeko Murata】【Awaiting shopkeeper's acceptance, please wait a moment】... Soon after, a beam of light pierced through between Himeko and Rita, and a man wielding a holy sword appeared before her. "So, are you my client?" (The main world of the anime crossover includes classic slice-of-life anime such as Saekano, Oregairu, Eromanga ga Sushi, and Oreimo; the supernatural forces include Touhou Project, Strike the Blood, Nurarihyon no Mago, and High School DxD; the side worlds are tentatively set to Honkai Impact 3rd and One-Punch Man, and will be added later.)

The maker of the Clow Cards, the witch of another dimension, the old man with a white beard who likes to be someone else's father, the golden flash of Konoha, and a scientist who, in human form, is on par with gods...

When the strong and wise men who were supposed to die in these virtual worlds were transformed into heroic spirits and came to the real world, they brought the knowledge of all worlds and helped Char develop the civilization of Blue Star.

What will happen when Hogwarts, the magic school, the Night Parade of a Hundred Demons led by Nurarihyon, the devil tree that grows devil fruits, or the sword immortal who rides the wind and slays demons between heaven and earth...all this knowledge from the myriad realms appears in the real world together?

This is a story about a dimension invading reality and fooling the whole world, as well as an adventure in the sea of ​​stars...
