TBH I don't know how this fight would play out since the two are in the same tier. But where would a fight like this take place?
Setting - Town
Prep? - LOLNOM8
In my opinion Ika wins due to her not really being effected by the Inkling's ink unless proven otherwise. The only possible method of Inklings winning is VIA Kraken or a bunch of force splatting Ika into something. Meanwhile Ika has much more execution options with her tentacles, ink, and weight abilities.
