Ah!

That hair and back... Now why Tenshi can recognise herself from the back is something you guys can think about. My guess is extreme narcissism

Let's chase after them!

Roger that!

It seems that other contestants have already noticed it, so here's an update

It appears that for some unknown reason, there are TWO Erin & Tenshi pairs! From our vantage point, we are unable to discern which pair is the fake!

There appears to be two identical pairs.

There are doubles of us on this field.

A pair turned up from somewhere and are wearing disguises of us.

*chitter* Katakana here is iesu, anyone who can translate bug-speak please go ahead.

That's great news. Let's keep low for now.
