I Can Summon My MiHoYo Waifus with My Phone!

[Genshin Impact + Honkai: Star Rail + Zenless Zone Zero] When he woke up, Wuming discovered that he had landed in an apocalyptic world. Other people awakened superpowers. What he awakened was... a phone? [The MiHoYo Character Summoning System has been activated] [Host is in danger. Would you like to summon a character for support?] Two lines appeared on the screen. Wuming didn’t hesitate and tapped [Yes]. The next second... An elegant woman with blue-and-white hair appeared out of thin air. She saw the giant rat, turned deathly pale, and hid behind him, clutching the hem of his clothes. “Th-there’s a monster!” Then she raised a trembling hand. Mademoiselle Crabaletta, Madame Chevreuse, and Monsieur Usher: the fight was over in three seconds. Wuming: “...?” Later, he summoned two more people. “Trailblazer, it’s been a long time.” The silver-haired girl in a mech suit had tears in her eyes. The fox-eared girl with a long sword at her waist sheathed it. “Phaethon, are you all right?” They said he was their Traveler, their Trailblazer, their Phaethon. But Wuming couldn’t remember a thing. Only sometimes... when Furina trembled in fear before a monster, an image would flash through his mind: beneath the spotlight, someone had stood alone for five hundred years. When Firefly smiled and said, “I’ll help you, no matter where we are,” he would remember the profile of someone gazing up at a sky full of shooting stars. When Hoshimi Miyabi solemnly numbered and catalogued the mutated creatures they encountered along the way, he could almost imagine himself amid the ruins, one person holding a blade, the other its sheath, sealing a demon sword together. He began to understand: they weren’t strangers. They were characters he had once genuinely loved from the other side of a screen. Later, he discovered that the apocalypse had been caused by an accident. And that accident was connected to him! The answers to everything were hidden in his memories.
