or the short version for you. get laboon is your sole only chance unless you willing to spend (a lot) of fruit to pull and stamina up to lvl up your characters.

With the units you have, leveling them up to be strong enough might be hard (none of them really help for the event).

As Light said, the best option is to farm Laboon; so clear story mode and farm the last two chaps to get him.

I will also agree: Farm Laboon. It is your only chance with what you have up there (don't forget to grab the crabs to finish your team on crab day).
And pray real hard to RNGesus while you farm, because that whale has not dropped for me yet... and I've been farming that mission nonstop since it first came out.

Reading the guide or watching videos of japanese guys eating the shit out of Mihawk is the best preparation besides fusing your characters up.
