As a guy who's seen death note, I flipped out, extremely excited when I noticed the death note references. I thought this game would be long and interesting, and end in Ryuk somehow being involved in his death. As someone who got the yandere ending, some part of me wonders if Zilas really did have a deathnote and was using it to make us kil- him. Perhaps that's why he said that 'he can explain'. I believe there's a major connection between this game and death note, and I refuse to believe there's no explanation.
