Thanks to the folks at 百合镇守府 as usual for the Chinese translation. By the way I should point out that the last page belongs to them, and that I am neither part of their team (actually they usually explicitly warns viewers not to reuse or reupload their scans, but I am of the opinion that warning others not to reupload fan content depicting copyrighted characters that they uploaded themselves is akin to a drunkard trying to preach temperance) nor do I endorse their interests/views.
