Ichigo looked back at Ggio, again.
Oddly enough, he actually could tell a difference in being closer to the little arrancar?
It was like...like some part of him, deep down inside, wanted to sniff out, and examine something...something about Ggio's reiatsu?

Ichigo blinked to rid himself of the thought, since it was unsettling at best.

"Um, Y-Yeah...it's odd for bugs to attract other bugs of the same gender."
He shrugged.
"Take him for example--"Ichigo gestured at the firefly busily inspecting Ggio's fingers with it's antennae."-- He's lighting up like that to find a girl bug, so they can make babies. Keep the species going."

Although, Ggio's last question brought Ichigo up short, and thinking about it helped him not to think about why he felt so fascinated with arrancar reiatsu.

"Um...I don't know, actually? Hmm."
The young shinigami looked out at the hillside, and the flickering of hundreds of fireflies winking glows.

"Maybe...Maybe the light they make looks all the same to us, but to them? To them all their lights are different. Special."
