Kunitsu-Gami: Path of the Goddess

Wild defiled animals are found at each regular non-boss level, they will run away as you approach them and disappear after a few seconds If not purged. For this achievement you need to purge 200 animals in total, the best timing to do this is during day time as you run around for preparation of the night. if you don’t proactively aim for this from the very beginning, you might need to hunt extra after completing your new game+ playthrough. Unfortunately there is no possible way to see how many you’ve killed so far, the achievement trackers don’t work on this game at all and no in-game visible statistics available.

Defiled animals can be deers, rabbits, birds, pigs, boars and snakes. Attacking them with any methods until their corruption is purged for it to count. They drop health items as rewards. It becomes much more easier once Soh's basic ranged attack called Archery (by default)is unlocked for 10 Musubi by completing and another additional 15 Musubi to unlock any charged ranged attack(hold and release)except the spider shot to one-shot them by charging while running. Charged ranged attacks need to be equipped first at Yoshiro’s tent by clicking a small node on the rope in front of 3 Tsuba Guards and select the one you unlocked earlier.

I don’t know if keeping on hunting and restarting the same level without completing it counts toward to this achievement, please leave a comment if you can confirm it works that way. I started to aim for those animals from the very beginning and I got my achievement near the end of my new game+ Playthrough. Thanks in advance
