Takumi could be replaced by some random edgy OC and pretty much nothing would change story-wise.
"Grr, I hate *insert protagonist/kingdom* I hope you riot in hell"
How original, there's nothing relatable, tragic, or interesting about this pathetic, whiny crybaby. NO amounts of issues excuses him for his shitty attitude.
This guy is a complete waste of time. Also he is a lame rip off of Shinon. Fuck Takumi.
