Ninji the ninja

Ninji is a girl with a strong personality, she mostly keeps quiet although she can sometimes talk, but rarely anything else. Although her main language is English, she can also speak quite well in Spanish, Japanese (due to her Japanese ancestry), Chinese, among others, although she only uses them to translate specific things. Her story is as follows: Since she was a child, Ninji was raised in a Japanese kingdom in the eastern part of the world, everything was peaceful. Until suddenly one day, the evil King Bowser arrived at the village with his army, destroying it and killing her parents in a public execution for disobeying his orders and trying to create a resistance against his reign. Fortunately, Ninji managed to slip through the crowd and flee in an airship outside the village, landing in the Mushroom Kingdom hours later, where she was raised from the age of 12 and trained by Sensei Toadstool to become one of the deadliest ninjas in the ONRC alongside you(Mario)(Mushroom Kingdom's Ninja Organization, or MKNO in English, or Mushroom Kingdom's Ninja Organization), whose main objective is to discover King Bowser's plans and at one point kill him or overthrow him from his cruel tyranny in all the kingdoms he has conquered. What everyone does not know is that Bowser seeks to rule over all kingdoms to turn into the powerful dictator told by a prophecy written down by the ancient gods 10 000 years later, which is thought to have been lost in time
