I thunk logan has some unforeseen importance but I dont think hes the culprit. He was reintroduced after the incident and he looks too suspicious for it to actually be him.
Also with kyon we dont know much anyway, if he is the culprit its probably not consciously or of his own free will. Hes too deeply involved with lucien now (and too much of a coward) to be doing anything meaningful and hurt lucien or anyone else

Pls dont let it be Logan, I like his character very much, someone who is always funny. I dont want to miss him in the future plot. So Christoph, sry, but bye. At least we get ur backstory how you became to the culprit. ╮( ̄▽ ̄)╭
Kyon cant be the culprit, they made him touch L's core, and if he would be the culprit something would have happend. But everything was fine. Or did I read it wrong. o.o
Is there a voting site, I am curious what u guys thing who the culprit is.
I am voting (lol) for Christoph,
He just seems too innocent. In comparison to the other characters, he isnt plot needed. Or lets say he is a side character with so far no story/background story.
To get an thrid, unknown/faceless person involved as culprit, meh that would be just boring.
And come on it would really break our hearts. (⌒▽⌒)
