QIf my main deck, evolve deck, and glory card are based on the same universe and my leader card is Yukino Bijin [Hometown Cheers], does it fulfill the condition for this follower's Fanfare?

ANo. If your leader has both a class and a universe, you must declare which your deck is based on before the start of the game. In this case, you would have chosen universe for Yukino Bijin [Hometown Cheers], meaning it does not count as a Forestcraft leader.
