Dunno, at the begining i thought this is going to be a good series cool fights, i liked the knight system itself, interesting story but the last 2 episodes become so stupid, the plot is so stupid without any reasoning and he just lets them do it, then they offer him a deal which makes no sense at all and he just takes it xD
until then i was hoping for a second season but i actually can see why this isnt going to be continued, same issue like the 7 deadly sins, cool anime itself but so much stuff going down that makes no sense at all ruined this anime for me, i still give it a seven
