I posted this very unfinished submission at the end of fourh thread, I didn't get the strenght to finish this before the next thread started, but it was supposed to go like this : the tengu watching the battle between the gang and small yuuka (flowerhead at the time), would fly away in the sky only to end up attacked by an eagle spirit. That eagle would later swoop down at cirno, who was in a lake at the time, and posses her. Then both would arrive at the battle in the balcony to help the gang, and yes the combination of both was supposed to reminisce of petshop from jojo.

Sukuna sure was mischievious in this story, even her castle radiates malice.
