"Spar with me, Renji?"
"What for? I might accidentally crush you."
"I need to get stronger. I don't want to lose a battle because I was weak."
"Ask Ikkaku to spar with you."
"No fair! You trained with Sado-kun!"
"That's because Kisuke-san asked me to!"
"Fine! I'll go ask vice-captain Hisagi for help, then!"
"Huh? What-"
"You called?"
"Hisagi, Renji won't spar with me!"
"Why do you want to spar?"
"So I can get stronger."
"You don't need to."
"What? Why?"
"Because I'll protect you."
Both Renji and Nana were caught off guard by Hisagi's words.
