Lucoa is a goddess worth worshipping. I can only hope that, with enough prayer, my crotch can briefly be buried in Lucoa's chest. There be no better way to ring in the new year.
Kun is just a less formal way to say "san". Is common between acquaintances and co-workers, and when seniors/senpai refer to younger people. Is not specific to a gender.
Also, i'm glad to see they are using the proper raws for this manga.
