"Lieutenant Isane Kotetsu from Squad Four?"

Isane looked up and screeched. There stood Ikkaku, for the second time since Unohana taught his captain a lesson. This time he held a wrapped box. The trouble was it was dripping blood.
"Yes?" Unohana stepped out from her office, having heard her lieutenant's scream. Ikkaku placed the bleeding box on the desk.
"To Captain Retsu Unohana from Captain Kenpachi Zaraki. Good day." With that he was off. Isane gulped as Unohana undid the ribbon.
"Is it another?" She questioned as her captain opened the box.
"Indeed." Unohana replied as she shut it. "Dispose if this will you? I need to address Captain Zaraki about these threats."

"Captain Zaraki!"
Kenpachi lifted his head from the scroll he'd been skimming as Unohana approached.
"Retsu! To what do I owe the pleasure?" He laughed as he stood up, holding his arms out as if to hug her. Unohana blinked but got to the point.
"Why are you threatening me?" She asked. Kenpachi blinked as he lowered his arms.
"Threatening...?"
"Not once, but twice, you have sent severed heads to my office! Why?" Unohana questioned. Kenpachi's face fell.
"You didn't like the gifts. Damn."
"The..." Unohana's mouth fell open slightly, "Gifts?"
"I read your history report. The first head belonged to a bully who cut your hair off back in the academy..." His eyes fell on her braid in a way that made Unohana feel uncomfortable, "And the second was a boy who'd run off with some floozy."
"You were sending me the severed heads of my enemies." Unohana clarified. "As gifts. Why?"
"Yumichika and Yachiru said it's customary when courting a woman to send her tokens of your affection."
"Courting-affection-" Unohana stammered, "You've been trying to woo me?"
"I have." Kenpachi placed a hand on the back of his spiked head. "I guess U messed up, huh?"
"Now that I know the meaning it's almost sweet." Unohana smiled at him. "Just no more severed heads, okay?"

She walked off gracefully as Yachiru dropped down. Kenpachi's eyes followed the other captain before he faced his Lieutenant.
"So no severed heads." He glanced at the candy Yachiru was eating.
"Where'd you get that?"
"Unohana's Ikebane Club." Yachiru replied. "You want one?"

The next time Isane looked up from her paperwork Yachiru stood there holding a bouquet.
"Special delivery for Unohana from Kenny!" She cheered as she put it on the desk. The little girl then ran off.
"Isane, what was that?" Unohana asked as she emerged.
"Captain Zaraki sent you flowers." Isane stated as she held them up to her. Unohana blinked as she took then.
"Lilacs.". She whispered, sniffing them with a smile. "Sometimes represent inner strength."
"That was different of him."
"Indeed." Unohana smiled, "No one else quite like him."
