I’m in Tiga, but I’m Nexus

(Ultraman multiverse, genderbend, single protagonist, mature beauty, universally adored, slight yuri, beloved protagonist, has a System) I’m begging you, please understand this: the protagonist is neutral leaning toward good, not a caretaker, and follows her whims. Whether she saves anyone is up to her. Questions like, “Why not deal with the monster before it appears?” or “Why save everyone instead of only the people the protagonist can save when she shows up?” are really getting to me. I can’t even remember the order the monsters appear in. I’m terrible at writing introductions. I transmigrated to the Ultraman world and became Nexus. I thought I’d only have a System, but I never expected the consciousness of the multiverse to take an interest in me as soon as I arrived. Had I become Noa’s daughter? The future “Ultraman Legend”? The moment I arrived in the world of Tiga, I beat up the stand-in, Dark Tiga. “Mingchuan, actually, I...” Daigo’s cheeks flushed as he stammered. “Daigo, Rena is a wonderful girl.” Daigo froze, rooted to the spot by those words. His open mouth slowly closed. “You have to face what’s in your heart. Are you really sure there’s no place for her in it?” Mingchuan smiled gently. Her smile was exactly as it had been the day they first met, as if time had never passed between them. “It’s time for me to clock out, too.” Mingchuan waved to Daigo, then turned and melted into the twilight at the end of the corridor. Her soft, gentle voice faded with her footsteps. “Bye-bye.” Daigo stood watching her departing figure and smiled in acceptance, but the image of the girl still lingered in his heart, impossible to dispel.
