Idea: Everyone who knew her loved Kushina and are absolutely pissed that Minato used her baby to seal the Kyuubi in (the fact that Kushina was involved somehow got left out).
Danzo raced into the Hokage's office which the Third Hokage occupied once more. The Nine-tailed fox had been defeated a week earlier, everything was returning to a semblance of normalcy, and he was praying that the report he'd received wasn't accurate. The Hokage seemed stunned to see the normally calm Danzo so flustered. The man in the corner, Hiruzen Sarutobi's student Orochimaru clutched the bundle in his arms in a more protective manner.
"Is it true?" Danzo asked.
"Is what true?" the Hokage asked.
"Did Namikaze really use little Kushina's baby for the sealing?" Danzo asked. He'd liked the young Uzumaki woman since he had met her when she was a small half starved refugee who had just made her way to Konoha. Her cheerful manner had brightened up every place she went, and he used to bribe the girl with ramen to play pranks on selected targets every once in a while. When the baby she'd been expecting and obviously gave birth to grew a litte older, he had planned on continuing the tradition.
"Yes." The Third Hokage said with a sigh. He had a feeling that there was going to be trouble. If the usually unflappable Danzo was this upset about the baby that had been used, who knew how everyone else would react. Ever since Kushina Uzumaki arrived with the group of refugees from Whirlpool as a child, she'd made friends wherever she went. Almost everyone who knew her liked her. Those who didn't like her generally loved her.
"That rat bastard!" Danzo yelled. "It's a good thing he's dead, or I'd have killed him myself. It's bad enough that the child he used was his own son, but the fact that it was Kushina's baby makes it alot worse."
