The first thing Renji heard as he made his way to Ichigo's house was a loud crash, followed by Ichigo….
Laughing?
Renji checked the hollow/Arrancar tracer again.
Yep, there was definitely an Arrancar inside the substitute shinigami's House.
Drawing his Zanpakto, he stealthily made his way into the vibrating house, jumping every time He heard another crash.
He got to Ichigo's room, and quietly opened the door.
ZOOOOOM! CRASH!
It was the Arrancar Grimmjow, fully transformed into Pantera….Chasing after a little red dot.
Renji turned to see that Ichigo was holding a small…device.
With a quick flick of his wrist, he sent the red dot rocketing up the wall, followed closely by Pantera, who bashed his head into the ceiling, before dropping back onto the floor.
Renji watched this a few times, before he settled down next the young Shinigami.
"I might as well enjoy the show." He thought.
