I’m still kinda building it and I do want to see some more events until I make more solid decisions on some songs. But the most solid song choice i have for Kote is Phoenix ft. Cailin Russo, Chrissy Costanza. No, it was not chosen just because of fire though that was part of it, can’t lie, but because music feels like it fits Kote and I kinda see Kote having a link with crows (partly due to the story of the Rainbow Crow).
Yeah, I imagine it is weird I bring up crows when the song talks about being like a Phoenix, but again, the reason for bring up another bird is due to the story of the Rainbow Crow. The basics of the tale is how a crow sacrificed its beautiful rainbow feathers and singing voice to bring the first fires to the lands below in order to save the other animals from an endless winter. Though losing much of how it used to be in order to help the other animals, (now with feathers completely scorched by the flames and its voice ruined from the smoke of the fire it carried back for many days), it also gain a kind of freedom due to its actions. The fire made its skin have a horrible taste, so few would want to hunt it and its lack of singing voice would also mean few would try to capture it as a pet. And if one looked closely enough, the shimmer of rainbow could still be seen in its black feathers and many would remember the selfless act it had done for everyone’s sake.
Kote may be very sore right now from how Leon and the kingdom treated him in the end, but it doesn’t change the fact that he had (in the past) more than once grasped the flames keep both parties safe. While he was scorned and treated as a demon in his last hour, Kote kinda ends up gaining a sort of freedom in his rebirth and comes to focus more on his personal needs. And though deeply burned by the people he saved and his former friend, underneath the wrath and pain still lies the kind, selfless man the White Fang members used to know.
Oops? 
We may not have all the puzzles pieces to a number of the characters, but we do have enough to create some form of picture to make guesses on. And its fun to see how right or far off some theories end up being (or watch how exactly future events may end up playing out).
