Am I the only one who thinks Amou could be the neighbour who killed Yuma?
Both use black triggers and are held to being strong opponents
We know little about the abilities of both but the appearance of each when using their abilities is described as monstrous (for the assassin its shown as their black trigger form being less than human looking)
Their hair looks kinda similar and we know Yuma and Amou have had no interaction at border to cause Yuma to remember the assassin
The main issues I'm having with this idea is the BBF pages that mention Amou joining 3 years ago, being apart of the Kido faction (that dislike neighbours) and him being in a normal school.
I'm not entirely convinced that the theory even holds that much merit but I think the possibility of character growth between Yuma & Amou as well as Mikumo & Kido (as if its true Kido is a massive hypocrite)
Would really like any extra ideas for or against the idea
