As you all are aware, Junjou Mistake the mini series manga will have it's own anime. So far, no word on when.
However, after watching the new episodes of Season 2 Sekai Ichi Hatsukou, I have noticed certain characters from Junjou appearing out of nowhere. You all have seen sleeping Misaki of course (I believe 2nd or third episode, I squealed of course), and the so called "Usagi Beer" .
I have heard rumor and read on the comments that Junjou Mistake might appear in Sekai Ichi Hatsukou season 2 close to it's ending season. Only thing we can do now is wait and keep a close watch on every episode.
I love the show and totally spazzed when season 2 finally came out. Keep watch the new episodes. If you spot something no one else noticed (don't spoil the episode of course) Junjou Related, comment about it.
Have a wonderful weekend.
Right now I'm a bit sick so I'll try to get better to post more for you guys
