Renji's eyes go directly to Seiichi's, just questioning. Whether that question is a teasing Really? or a wry Who do you think you're fooling? or even Will I be getting all the best data on this subject direct from the source or will you force me to resort to underhanded means? is up for interpretation, however.

"Poor Von Aegir won't know you're being shameless, if nothing else," Yanagi added. "I thought shameless people were more your type, anyway."

"Since when does Yukimura have a type?" Sanada snapped, suddenly animated again.
