[National Fate] + [Ensemble Cast] + [Roleplay] + [For Fun] + [Livestream] (But the story sticks to the game's main and side quests!)
After transmigrating for over twenty years, Yun Maoning is finally sought out by a god. Except it's Aha... Aha installs an app called "Honkai: Star Rail: True Edition" on his phone, letting him raise characters' affection in the game, invite them into a group, and roleplay as them to gain their powers.
Ruan Mei: "Researching a lifeform identical to me? How interesting."
Yunli: "This sword is crying. Aren't you going to take it?"
Fu Xuan: "Group owner, you bully."
Tingyun: "Call me your benefactor, quickly. Otherwise, you won't be acting like a young lady."
Yun Maoning is completely numb. Aha gave him good luck, but is this really National Fate? He's already struck it rich himself. All he wants is to keep his head down and slack off, but National Fate isn't fun at all!
(Most of the Chrysos Heirs will appear in the National Fate forbidden zone, including Cerydra, Hysilens, Long Night, and Evernight. The Great Herta from 3.0 will also make her entrance after around chapter 30. The protagonist won't roleplay as many characters, though. The Chrysos Heirs are roleplayers, not members of the chat group.
All the Xianzhou natives will appear in the game storyline.)
(Viewers and national storylines take a back seat later on. Some character settings have been changed. This book sticks to the main and side quests! It's not a traditional National Fate story: there are no teammates, but plenty of characters appear, such as the Chrysos Heir family and some familiar Xianzhou characters. There may be yuri, thanks to Aha. Please don't give it a bad rating over that. This blurb isn't doing the book justice, so head to the story and have fun with Aha!)
