The rabbit landed by Yumichika Ayasegawa, who didn't know about the rabbit's ability, and promptly picked it up.
"What a beautiful little rabbit!" he exclaimed, only to have his face mauled off.
Ikkaku heard Yumichika's screams of agony (if your face was getting eaten, you'd scream, too!), and rushed over, shouting "Grow, Hozukimaru!".
The rabbit, looking unamused, turned the moisture in the air into ice, and sent it at Ikkaku. Ikkaku avoided it, but the ice drained his Reiatsu, and after 3 attacks, he collapsed.
The rabbit, thinking he was dead, flew off in search of more flesh.
"Ken-chan, it's terrible!" Yachiru Kusajishi, lieutenant of the 11th division shouted to her Captain, Kenpachi Zaraki. "Feathers had his face eaten off, and Pachinko-head was lying down face first on the ground!"
"Sounds like a damn strong opponent to me." he said. "I'll bet this fight'll be better than the time I fought Ichigo."
"Ken-chan, I know the rabbit's around the corner!" Yachiru shouted! Considering Yachiru's sense of direction was worse than most peoples', that was not the case.
The rabbit landed in the 10th division barracks, and began to kill and eat several unseated 10th division members, but suddenly, Retsu Unohana, captain of the 4th Division, walked in with her Lieutenant, Isane Koetsu.
"Isane, hand me my Zanpakuto, and leave the room."
"Why must I leave, Taicho?" Isane replied.
Unohana smiled ominously. Isane gave Unohana her Zanpakuto, and left the room.
The rabbit looked at Unohana with a look of mild irritation.
"Bankai" was Unohana's reply.
Unohana's blade liquefied, and reformed into a Stronger, crimson blade.
"It's been a long time since I've seen an opponent worthy of my blade!"
