'Truly as if festival, which stired up Gensoukyou, began to unfold even further.'
Meaning unclear.

Rephrased, now should convey the meaning.
Help with more natural expression would be much appreciated.

I'm still unsure what it's meant to say - the coming festival that stirred everyone's hearts, is finally starting?

After a second look, I parsed this line slightly wrong. Should be fine, this time =\
