The way I read this, this guy hasn't any redeeming quality. He's a total piece of trash. He blames other people and circumstances for his own failure at being human. I almost pitied him, but after thinking about it, he doesn't even deserve pity, he's defiling everything he touches.
Obviously we get a glimpse of two different timelines. The one where he ends up a greasy otaku dying naked, and the one where he ends up a ladykiller, probably as a result of really evil deeds. And stabbed to death,
And the story seems to play a third timeline, where Homura tries to put a stop to it.
I agree with her: this guy should be erased from all timelines. Just disappear from this world already.
I don't know if I can bear to continue to read this, because I'm like Homura when watching his face. Burning with hate.
It's not that it's a bad story, it's just that I don't like one bit the emotions it stirs up. That character makes my soul shrivel.
