This mission will become available when you complete the "Bloodthirsty Blossoms" side mission. To start this mission, all you have to do is approach the tree trunk and examine it.
Akito and KK locate the corrupted tree.
From: Gardener
Soon after you examine the tree trunk, enemies will start to appear. There will be quite a few of them, and in successive waves, three in total, they will be increasingly more powerful opponents.
Execute the proper hand seal...
...and after a while you will receive rewards and this mission will be over.
After Akito and KK cleanse the tree's corruption, it blooms beautifully, if out of season.
