Moe Academy: the Mysterious Princess

The mysterious princess accidentally lost her memory and traveled through time and space to Moe Academy. What story will she bring? "My dear, you forgot about me... But it doesn't matter. I just remember you. As long as you look back, I will always be behind you..." "Nuo Nuo, you saved everyone but yourself..." "Nuo Nuo, we miss you..." … "Everyone, I'm back!" "Everyone, long time no see!" _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ CP: Ukenana (PS: The heart-throb heroine, whether Nuo Nuo will be with them in the end is to be determined. People from the original world of Nuo Nuo will also appear later. Babies, you can guess where the original world of Nuo Nuo is, hehe. It may be a bit different from the original plot. The character is OOC, so don't comment if you don't like it, thank you)
