Miyu and Tensi

It's a bit common for these two girls to appear together in independent publications. They are really lovely, but ... who is this Miyu friend? Is she a nurse? a ghost? an angel?

She is always kind to bring tea to Miyu ... an excellent companion!
Well ... the truth is she's not really a Vampire Miyu character; She is part of a manga called Magic at 3:00 pm, by the same author of VPM.

It's extremely difficult to find more information about this other manga, I believe that very few people know Magic at 3:00 pm ...
This new friend of Miyu is welcome, along with Yui, Shiina and Larva ... Miyu needs precious friends to forget the loneliness a little.
I think Tensi should appear in Miyu mangas from time to time ... why did not Narumi have this idea yet ???
