The power is quickly spinning its wheels.
Munakata never uses his power pointless and maybe that's the biggest fault of all.
His self-restain eats him alive, he only lives for the next opportunity to unleash the the blue.
Violence is planted in his well controlled heart. Of course he doesn't show it to anyone.
He watches the sanguinary treasure in the mirror and he's feels incredibly happy.
When he meets the Red King for the first time, he realizes there's a stud on Suohs right ear conch now.
Vaguely he wonders if Suoh has been choosen because of his egoistic magnanimity too.
Their fight is a dance, their attacks are plays. They smile the whole time and when Munakata sees the red flames, he feels excitement waving trough his body.
There's no need to hold back against Mikoto Suoh.
And maybe that's the one thing that gets them addicted to each other, because they're equals and there's no need to hide. They're just the same.
When he realises that he's loosing, it's already too late.
