Okay here are Botan's quotes that I have for now. I know these are all really small, but it's a headache going through all of the manga at once. So here are the quotes I have for now:

"Hah! Hit a perfect grounder that time."-Vol. 4
"Exactly!! We must take the whistle and distroy it!"-Vol. 4

"Ohmigod! Kuwabara, you were listening?!"-Vol. 4

"But this might be the calm before the storm."-Vol. 4

"I'm staying for tea."-Vol. 6

"So? long-distance relationships can be very romantic!"-Vol. 6

"There was a strong debate in the underworld about telling Hiei in the first place. We compromised by assigning him to deliver that tape to you."-Vol. 6

"She didn't blink when I told her about the tournament-she just snarled "take me there!"-Vol. 6
