[Crossover] Saving the World Again Today

Chaldea, busy saving the world, has received another mission. Having coveted the power of the "Outer Side" and gorged themselves on it, Gaia and Alaya finally have the time to tidy up the "Inner Side" worlds under their care. Then they accidentally discover: one, two, three, four, five, six, seven... Why are so many worlds destroyed or on the brink of destruction? Gaia and Alaya: "..." Gaia and Alaya: "Brave young men and women, the important task of saving the world is yours!" Roman: "Wait a second! Ritsuka and Ritsuka, say something too! Anyway, I don't want overtime, absolutely no overtime!" The Fujimaru siblings: "We don't mind..." Saving the world is something they're already used to. And so the siblings once again set out to save the world, with delightful results: countless worlds are able to survive. There's just one problem. The Fujimaru siblings: "...Dad, exactly how many people hate you?" Heroic Spirit EMIYA (decisively): "I'm not taking the blame for this. It's all Emiya Shirou's fault." The Seven-Color Shirou Squad: "Meow meow meow?" Content warnings: 1. The stories are linked by FGO's Ritsuka siblings. 2. The Ritsuka siblings are Rin and Shirou's children. 3. Ritsuka and Ritsuka are just the connective thread; the protagonists of each story are transmigrators. Mostly BL, with some BG. 4. Alternate versions of Shirou appear. There will be character deaths. I love the Red-Green Erotic Duo. Finn has a major role, and I'm a huge fan of the Captain. 5. This story is also known as Gaia and Alaya, Could You Stop Setting Us Up?, Please Give Me an Upright Transmigrator, Chaldea Is Packed, and The Seven-Color Shirou Squad. Theme: Please keep moving forward
