I took me a while to notice this, but anyone see something missing?

I'll give you a hint, its the whole reason Keima does what he does.
If I'm wrong just explain it to me, thx.

Perhaps his "necklace" isn't showing because his hole body is illuminated by Elsea's magic uhm this texture whichs is always flying around her. The hole meaning of the swimming pool scene was to show himself to her in the most attractive way, but we will find out if it gets corrected in the collectors edition or something like that.

Probably because this is an image from outsider's point of view. And outsiders are'nt supposed to see this thing.

It was, in fact, a mistake. Fixed in tanokoubon. 🤣
