Deserves +301 points for their Japanese.
I don't like it, but I'd say that the latter would win. Those three, being shounen's main characters, are ridiculously overpowered, so even if they get killed, they won't die. They will just awake another hidden hissatsu power and win in the end. On the other hand, if taking only characters without author's deus ex machina plot twists, the winner would undoubtedly be the fate team.
Claire should win. He is much faster than his opponents no matter how you look at it
Not much of a fight. Johan is not suited for combat and Light, even if he can write faster he still needs 40 seconds for it to take effect, assuming he knows their names. It also brings up a certain problem with Death Note - Johan doesn't have a name, so how can Light kill him?
Johan's can manipulate you into killing yourself if he touches his forehead
It doesn't work like this though.
