After meeting up with his birth family, Corrin couldn’t help but want to stay by their side - this was his family too, right? This was the land he was meant to have grown up with. These where the siblings he had been forcefully taken away from. This was his birthright.
It broke his heart to turn away from the family that raised him - but taking up his Hoshidian name, Kamui, he steels his heart and does his absolute best to protect his family. Both sides, if he can help it... but there is no saving everyone. And though he never meant for his returning home to hurt his adopted family as well... he knows that he’s caused them unnecessary grief.
Having decided to return with his adoptive siblings back to Nohr - after all! They may not be his blood siblings, but they’ve always been his family. But, despite this logic making perfect sense to him, it appears the king is enraged by his return.
He can’t put his finger on it. He’s unable to understand why the king is so upset by his return and continuously pushing him to “prove his loyalty” all of a sudden... But, he’s doing his best to support his family. And his family is doing their best to protect him as well.
In this verse - he’s learned that his birth name is Kamui, but usually answers to Corrin instead. His Nohrian name.
( This verse is only available upon request! I default to Birthright or Revelations usually. :’3 )
When faced with an impossible decision to pick one family or the other - Kamui makes one very important decision: He won’t chose ether side. He won’t betray ether side... and so? He and Azura make a dash for it. Leaving the area and having both sides declare him a traitor, due to his inability to chose ether side.
This eventually leads him down the path of multiple truths - things that he had never known was going on behind the scenes, and? Opens the opportunity to save all of his family, both sides, from the invisible puppet masters behind the scenes.
Fire Emblem ( crossover ) verse! To allow Kamui to interact with Fire Emblem characters from various titles. This verse is still heavily under construction!
