He knows Muzan. Kaigaku doesn't need to see red eyes to know Muzan. He doesn't need teeth and a sneer and a low voice that makes his knees quake to not recognize Muzan in his teacher.
He almost wants to drop his classes right here and now, and avoid him forever. But no, he's an accomplished scientist. He's smart. He has made his own accomplishments. He will not need Muzan or Daimon or whatever his stupid name is now.
And yet he does. He hates it. He's saved with the smell of fire (nothing like lightning but everything like lightning.) and pounding fists and overpowering might and he. Seethes.
It should be enough. He should be pleased because he lives another day to succeed and he is not weak.
But he's not strong either and so he seethes.
