well its like, we're just starting off with just normal genin and doing D-rank missions, we haven't even done a single C-rank yet, but that is the next arc. there has been attacks on said genin by a missing-nin that has been nicknamed Futility-San, some of which have been Team 3 but not all of them. there is some political/family troubles happening as well but its slow so its not really has affected much yet.

Kimiko Ishikawa herself is uh....pretty much the Sasuke/Neji/Vegeta/Katsuki Bakugou/Shouto Todoroki of Team 3, so don't be surprised if she is a bit of a jerk and that it will take a long time for that to change, and that her goal is basically to learn all jutsu she can, mostly using her paper bloodline and fuinjutsu to do it. yeah, she is ironically more of a threat of going crazy godlike than your character is, I'm just making sure I know to keep it reigned in and its more about the journey than the destination really because I have plans for her that examines and explores the journey, and that its kind of a goal that won't really end in any definitive sense probably.
Jirou is her older brother who didn't inherit the bloodline trait and he is basically her Itachi, minus the clan genocide. the Ishikawa Clan is one that escaped from the Bloody Mist purge, was formerly a Mist Clan and is now recovering, and she is basically their genius heiress whom everyone places high expectations on to succeed. like don't worry, Kimiko is probably the darkest most screwed up character and the biggest concern, so your good.

the support character I play in team 3 is Yuyuyu which is nickname for three names that begin with "yu" she basically is a genjutsu specialist who wants to start a spy network and learn all the secrets, so she isn't a concern power wise or anything, she is basically just there to be the sane one and to help everyone else with things, mostly social/deception stuff. she is the one who will take backseat when Team limitations are brought up so that your character can participate as she is a infiltration and genjutsu specialist, not a combat one in a group with two other combat focused shinobi so her stepping aside to allow you to do your thing for a more focused combat team 3 makes the most sense in and out of character.

I will let Igor explain Usagi when they reply
