this tittle can be interpreted in different ways....
cute as always, and id like kei and nao to get together, but i get why author keeps it absolutely romance free (but a little romance for secondary characters wouldnt hurt)
and look at the girl with camera at page 20..
is she a witch too? she's cute..
she looks human to me, it just that i don't know if she's a local resident of that dimension, or just visitor like our girls..
