AV OPEN Series Returns?

[BDrake]

In March there are some films coming out similar to AV OPEN series. The label is Haru no Pants Matsuri:

no, just another studio, nothing special

 

[vietbub]

no, just another studio, nothing special

I don't think thats correct. Each of these videos are coming from a different studio

 

[M1N0RA]

no, just another studio, nothing special

Did you even bother looking at the covers?

anybody figure out what is going on with these? it does seem weird that they all have the PFES-nnn code but are from different studios.
