Didn't know that that there was a another numberfag holo site. It even has English. Just tracks sub growth from the beginning and has a 1M forecast page. It's interesting because it has every chuuba in there and it tracks their sub growth from debut date every day so if you are interested to learn when a specific jump in sub growth for a girl happened, you can see it there. I saw it while trying to browse l what the cosplayer for Marine looked like. She looked pretty hot. Her PC case looked really nice too.
