#ikkaku

Kenpachi is there to protect her, to defend her no matter what, to bring her anywhere she wants, to bend to all her wishes.

Ikkaku is, after Kenpachi, the one who interact the more with her as what she is: a little girl (more than a vice-captain). He's also the one who learn her how to control her reiatsu. And he's also the one, with Yumichika, who learn her how to read, to write and to count playing games with her (it was the only way for her to learn something).

Yumichika is the more deferent with her, calling her "Kusajishi-sama" all the time (when Ikkaku often calls her Yachiru (Kenpachi doesn't care by the way)). He's the one who's there to comb her hair, to read her stuff (not necessarily fairy tales) and to chat for hours with her.

They won't say it explicitely but they love her (and they are wrapped around her fingers).
