I might be wrong, but I'm pretty sure it's Shizuka Nadeshiko.

shizuka isnt in the game

Neither was Shira until the second month of the spring season

it is shizuka, according to the clues

ok but shizuka aint a princess, she's nowhere referred as a princess ;-; just leader of a village

after a few minutes I have realized my mistake, deep into the internet, shizuka IS referred to as a princess

3 Clues I have are Female, Princess, and Engaged, so it is pretty much Shizuka. Seen in an earlier post Jib said first name was enough, but might want to add her last name on 1st or 2nd guess. I did put Guren down as my 3rd guess to be safe.

hello

aaa

It could be also Tsunade, she is slug princes and was angaed to Dan Kato :o

Well the 4th clue is Nadeshiko Village. If that is true it is for sure Shizuka, but this was just leaks from a while back. I haven't gotten the last clue yet.

Mysterious ninjas are ninjas that will be added to the game. So you don't guess ninjas that are currently in the game. People that have already did their research already know the answer.

*Caught* ..Chiriku...Guren...

with the 3 clues you posted and I read it is more likely Kaguya Otsutsuki

first clue: female

second clue: princess

third clue: that you guy say engaged

depending on the fourth clue will tell it

Kaguya Otsutsuki lul almost everybody already knows its Shizuka based on the clues.

tbh was hoping for the non pain version of female animal path...
