Yea!

Yeah!

AH!

Wow! Another awsome chapter!

Cool. Sorry I haven't read this for a while.

More comments.
The dialogue in the story seems forced and unreal. For example you switch randomly from extreamly formal language to slang, thats ok if you have one formal character and another character who speaks in slang, but you don't have any consistancy, one minute someone speaks in pure slang the next they're formal. It makes the dialogue seem forced and the characters wooden.
Your character's don't seem to respond to anything with any consistancy either. Kaiyo's response to the news of his friend's death seems frankly stupid and unrealistic, as does his response to Jin's explaination of angels and demons. Kaiyo may well accept the existance of demons, but being told that there is a secret war going on and demons want to destroy humans would be a bombshell for anyone. It's not the sort of information you respond to by saying 'oh my god'. You say that when you find out your boyfriend is cheating on you not when someone tells you they know people who want to wipe out the human race.
Another minor point, Kaiyo seems to miraculously recover much faster then Sakura, another thing which makes this seem unrealistic. Sakura is still in critical condition but Kaiyo recovers in two days and is walking again.
This kind of thing makes a story seem childish. The bad quality of the writing destroies any merits the plot might have had.

I don't think you introduced your characters very well, and you didn't give really let them develope before killing them off. You should give some more description of them even if they are going to die quickly, they are meant to be the main character's best friends so they deserve some description.
There is hardly any background description and it seems rushed. The story moves too quickly.
It also seems unlikely that after seeing his friends killed or near killed by the creatures that Kaiyo would just grab a near by weapon and start fighting them. It doesn't seem to fit.
