They technically took the spot in August, but now that it's held through to September with increasing revenue from Madoka, they're potentially set up for some long term dominance.This is driven by Fate/Grand Order, the #1 top grossing mobile game in the world right now, and Puella Magi Madoka Magica Side Story: Magia Record, which to my understanding is like Fate/Grand Order, but for Madoka.Also, these are games published by Sony's Aniplex division, and should not be confused with their Sony Interactive Entertainment's PlayStation driver ForwardWorks division, which is doing poorly.Also of note is that a foreign developed and published game (Lineage 2 Revolution) is in the top 10, which is basically unheard of.Source: https://www.appannie.com/indexes/all-stores/rank/?store=all-stores&country=JP&date=2017-09-01&category=overall
