Flawless Sir Alonne Boss Fight NG +8 (10) unique death animation

I tried bow, duel bow and even prostration before fight, but it seems that Alonne just does not react on them, maybe I did something wrong, I dont know. However unique death animation is real and he shows it only if you defeat him without taking a single hit. Great boss, awesome fight, godlike music. Thank you for your harsh swordfighting science, Sir Alonne.
