Raito, "L is an irreplaceable person to me".
Also Raito, "Remu, please kill L".
My goodness, reading Raito's manipulation of several characters in one chapter!
Lying to the girl in his class that he likes her.
Telling L to his face that he's a friend.
Twisting Remu's love for Misa into a weapon.
Just when you think he can't get any lower, surprise!
