Reborn as Morgan, the Paradise Fairy of the Fairy Britain Lostbelt, the girl remembers the miserable fate awaiting her and feels a headache coming on. Within, she has five treacherous clans, three calamities, and a self-destruct mechanism for Britain. Without, she faces Chaldea and the Alien God. Fortunately, she refuses to submit and can transmigrate to other worlds. So Morgan starts frantically importing things from other worlds, determined to turn the Fairy Britain Lostbelt into a beautiful and stable nation.
Starting in the Fairy Britain Lostbelt, she barges into Chaldea's version of Fate/Zero, obtains the Third Magic in Fate/Apocrypha, raises super-dangerous species and makes Imperial Arms in the Fairy Britain Lostbelt, and seeks the method of creating a boundary in Date A Live from the Origin Spirits... Of course, every wretched fairy deserves to die.
When Chaldea's Master, Fujimaru Ritsuka, finally reaches the queen after countless hardships, the familiar figure on the throne asks, "What do you think of my country? Is it beautiful? Is it like a dream?"
Fujimaru Ritsuka (female) swallows, recalling the towering monsters and all manner of divine weapons she saw along the way, as well as the countless Fairy Knights. She can't help nodding to Morgan on the throne.
P.S. Gender-bender yuri.
