One reason why Kanako is good to have is for a water replacement in a pet training team. If you have a Kanako who can do the healing then you don't need to have a water on your team.
Let's say you don't have points on a water for an e-remote and you're training nonburstable pets with the rest of the team. Throw a decent level Kanako on the team of the one that has the e-remote (nonwater) and you're in business. All you need is SP food. : )
