How to Obtain
Only through Evolution
Pretty much the same as Petty Officer Coby, except different type/classes. Common staple on many QCK teams (unless you get legend Doffy/Marco, and even then Kaku is good for speed runs). So, relatively useful to say the least. See notes on Coby for more on this type of character.
Better QCK orb boosters? Yes, there is one, but he is a Legend: Heavenly Demon Doflamingo who gives you a 2x bonus. If you have him, you can consider Kaku mostly obsoleted, but until then... (Ok, you can also consider Marco the Phoenix Whitebeard 1st Div. Commander as better (1.5x bonus+full heal), but he is also a legend, so...). And again, Kaku's CD is still lower.
Socketing note: the usual choice of 2 out 5. Since QCK team often run Enel captain, Auto-Heal is worth considering if you are aiming for level 5 AH.
