A Crossover Anime/manga Business, Starting with the Ten Holy Blades Saving Himeko

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.)
