While Pikamee going to Vshojo isn't the greatest choice IMO, the fact she's going JP will be a big help, Kson is a tard at times but at the very least she doesn't have near constant bullshit going on. (though that might just be because there is 2 going on 3 members.)
Now as for when she got signed, i can totally see Vshojo signing her on after her graduation, maybe they had some talks before but I doubt this was in the works before February, I can totally see them rushing together her assets for her to debut.
