Li An, who was reborn with his memories intact, arrived in a country utterly different from the one in his first life. He thought he could use his memories to get a head start, but he knew just as little about this new world, and still had to build his second life from zero. This was also a country where everyone was a soldier. But who would bother with close combat when they had ranged skills? Li An was determined to train himself into a long-range mage. How do you live a peaceful, smooth life in a world that defies everything you know? Li An and Jia Ao's heartwarming everyday life is here for you to enjoy. (The protagonist is initially called Lin Xi, his name in his previous life. He later takes the name Li An.)
A note!!! When I write fanfiction, I put my feelings into it, so Ultraman may come across as more human. There won't be flowing hair, bleeding, or tears or anything like that, but I may occasionally write emotions that feel more human, so please don't criticize me for failing to capture Ultraman's divinity. This is an out-of-character work, drawing on many sources: official and unofficial canon, rumors, TV and stage-play settings. If something doesn't make sense, it's either Ultraman's telekinesis or my own headcanon. My headcanon is mountain-sized, and the younger brother calling him “Nissan” and the son calling him “Oyaji” are things I personally love!!! The setting has Zero growing up beside Seven, so you can think of this as a parallel universe. While writing, I kept imagining them cutely calling each other those two names, so the story will be full of them.
That's all I can think of for now. I'll add anything else if it comes to mind.
