Written at the front: The author is a stepmother, so the protagonist will definitely be miserable. The article has no CP. I originally created a character, but I didn't want her to be with anyone. The author's writing style is not good enough to write down the ideas well, so he makes do with it.
Protagonist:
Name: Alga Girl/Sakabe Tamamo (referring to the legend of Tamamo, so I'm just incompetent and lazy in naming)
Setting: A girl who travels to "Naruto" for the second time (I once wanted to create a male account, but after joining Team 7, it was not good to form a group of three boys. I thought about it and forget it). Both the memory of the original world and the memory of the last time have been worn away. He has the aura of Kyuubi and Asura (not chakra) on his body, and the existence slowly gets closer to the tailed beast under the influence of this; he has a deep psychological shadow on Uchiha; he hates ramen (if he eats too much, he gets tired of it); he doesn't need to eat specially; sometimes he feels that Naruto is very familiar.
As for physical skills... Average?
Ninjutsu: Mimetic Nine-Tails Jutsu (it's not the Nine-Tails after all); Fox-Clone Jutsu (but it doesn't affect the clone); Transformation Jutsu (as a fox, it's better to know this); Sky Roar Cannon (set to be close to the tailed beast, let's use a long-range one); Killing Stone Fire Circle (range poisonous damage? It's nerve poison anyway); Wind Release can still be learned if you learn it.
This article does not include the cp, and the added protagonist does not belong to anyone else.
There are more characters, so I still want to change something, but I don't plan to make the protagonist so talented. What was written should be a very frustrating plot. I hope it won't turn into a Mary Sue, although I don't know what a Mary Sue is.
P. S. If you choose no cp, you will be assigned to pure love, so you have to choose romance.
