The first real fight they had had was after Kuukaku had moved again, this time into the outskirts of Rukongai, and had forgotten to tell Soi.
She trusted Soi to have no problem looking her up.
So when her girlfriend finally came knocking two weeks later, the last thing Kuukaku expected was to be slapped.
And when Soi started yelling at her, she had flared up and returned the verbal attacks.
"Who d'you think you are, to restrict my freedom?!"
It wasn't until Soi stepped back as if she had been pushed away that Kuukaku saw the tears in her eyes.
And only when she had turned and fled did Kuukaku remember how painfully insecure and afraid of being abandoned Soi was.
Less than three hours later, Shiba Kaien had shown up on the doorstep of the Second Division, bearing an apology from his sister.
