The Witch's Special Envoy

“Transmigrating” to a new world and beginning a new life sounds pretty great, but is it really? When you transmigrate, you are completely severed from your past. The longing of family, the memories of friends, the love of a beloved: these sincere feelings are cut off at their roots by transmigration, becoming autumn leaves swept away by the wind and leaving behind only a sorrowful sigh over a shattered family. Are you still worrying over a missing family member? Still fretting over a friend who has vanished without a trace? Still weeping day and night because your beloved's whereabouts are unknown? Then come to us! The Transmigrator Affairs Processing “Company” is at your service. We can give your loved ones your regards, bring back news, or even find the poor souls lost in another world. Your needs are our mission. Of course, everything above is nonsense Lin Zhenxi, an outstanding employee of the company and a Grade C special envoy who has already visited six other worlds, has this to say: “I really don't get why so many people want to go to these damn other worlds. All I want is to go home.” A crossover of multiple anime and manga series, with characters crossing between worlds. Female protagonist, no romance or marriage. Pure magic in the early story, magic-powered technology later on. Worlds already visited in the background: Harry Potter, the Scarlet Devil Mansion in Gensokyo, The Night Is Short, Walk on Girl, Magical Girl Lyrical Nanoha, Puella Magi Madoka Magica, and Date A Live.
