Not technically H!P, but close enough.
In April, I was in Japan and went to the Super Potato in Ikebukuro, the retro game store. I saw 3 girls in yellow/blue outfits.
(This is my photo, as I was waiting in line to buy something.)
At first, I thought they were maybe store clerks, walking around the store. Then when I went to the counter, I saw them interviewing store clerk, with pro style cameras. Never got a good look at all their faces (I didn't want to just keep staring), and had no idea who the girls were, and had no way of finding out.
Anyway, yesterday I came across a pic from a show called Game Maniax with girls with the same outfits, and Marin Miyazawa (LoVendoR) was one of them. Finally with something to go by, I eventually found the episode of the show that was being filmed, and Marin was one of the girls I saw.
The girl in the back of my photo is Marin.
This is the video, and that segment at Super Potato starts at about 2m48s.
I can't help but wonder what I would have done if I'd recognized her then.
On this day, after I left Super Potato, I went to the ANGERME CD release event at Sunshine City. Was a good day.
