What's the matter Reimu? Wasn't this your family's easy place? You don't find it easy anymore =3

I think Nazrin is saying:

"Reimu~I guarantee you! We will really ' easily ' eat you up! Not even a single residue will be left!"

I think that ' easily ' part (or at least I think that's what it says) should be replaced with 'take it easy'

So maybe

"Reimu~I guarantee you! We will really 'take it easy' and eat you up! Not even a bit of residue will be left!"

Anyone wanna help out and check?

That's pretty much what it is, Kiri

Predator Shous and Clever Nazrins. I like them
