Genshin Impact: Let Me Take the First Seat.

After the destruction of Camrea, Miss Knight, who lost her hometown and was living in a foreign land, was picked up by the Ice Queen and brought back to Winter. She was named Yusfana, codenamed "Rose" and "Captain" and became the first executive officer of the Fools. In order to repay the Ice Queen for saving her life, she made up her mind to swear allegiance to the Ice Queen and devote herself to Her Majesty's ideals. Later, in order to protect Zhi Dong, she had a battle with a demon god and was seriously injured, and was forced to sleep for four hundred years. When she woke up again, the world had changed drastically. Why have I lost so much strength? When I was at my peak, my strength was comparable to Her Majesty the Queen. How does this work? How can we help Her Majesty the Queen fulfill her wish without strong strength? How else can I repay Her Majesty the Queen for saving my life? In order to help Her Majesty the Queen win the Heart of God, she risked her life. If she was not strong enough, she would forcefully absorb the power of others. Mondstadt's Dulin remains and Fontaine's Erinas remains could not escape. What devil's residue, this is obviously a panacea to help me regain my strength. What prince of the abyss, the loom of fate, the great cause of restoring the country, pursuing eternity, becoming a god? None of them are worth mentioning in the face of the Queen's magnificent ideals. What? Sora, are you a reborn person? I don't care about this or that. As long as I'm here, no one can stop Her Majesty the Queen from changing her ways. But as Yusifana completed more and more tasks, she found that Her Majesty the Queen looked at her more and more wrongly. "Your Majesty the Queen, please respect yourself! There is a difference between a monarch and a minister. I am just your subordinate and cannot be your lover." (The protagonist has the strength of the Seven Gods, and there are two heroines)
