To translators: it would be nice if, after you translate every speech bubble (or every sound effect if there are no dialogues), you could press the "mark as translated" button. It will add the relevant tags to the picture so that it will appear when searching for translated pictures. And don't worry: this time it works ;)
Adult yukkuri in this story is very durable. Anon here has a nice knowledge of them, he purposely broke Reimu's left braid to immobile her. Normally, a teen can kill fully adult yukkuri with just one kick.
