Wow, this is a lot to process. Spoiler alert...
cant believe i had a crush on Kaius,(my dubious side on action), i was expecting more from his part, but it is what it is, doing that is far from redeemable, killing all those people, but who knows what wait for us on the next chapter... though im not very hopeful
You said you wouldn't let anyone unsatisfied or upset abou the end, but seeing this i doubt it, there is always who doesnt will like it and that's okay, just don't let the history be distorted
