It's Snake on the moon and... hold the phone, that isn't the Ayaka Kurusugawa I know. This foe known as Rapied Ayaka, who is related to Comode Serika, is a quite cheesy and repetitive agressor with bloated defense (1200 HP and 120 defense? Come on...) who will try to pound on you with a very quick speed (as her name suggests). Fortunenly, her AI has set patterns which can be easily exploited and Snake's no slouch in the defensive department.
