Comparing Yuki to Light from Death Note oh wow. What an exaggeration. A jerkass move, I guess I have to agree. In the long term what Yuki has done will have consequences, but I like that he is growing as a character. He has a lot more belief in himself than he did at the start of this manga.
No matter how dedicated Yuno is to Yuki, she's got to learn to have some sort of restraint, no matter how small in this life or death game. This is probably one of the few situations (in this entire game and beyond) they got themselves into where violence didn't have to be the solution. And now they have an awesome ally in Akise.
I won't be surprised if my defending of Yuki goes to shit when I read a future chapter of Hinata betraying Yuki and Yuno being right all along. AGAIN.
