Wait a Squid, Aren’t You on My Side? / Up for a Squid-Celebration? / Wanna Play With This Squid?

Ika meets lifesaver, Gorō Arashiyama, though gets annoyed when he doesn’t live up to her definition of "protector of the sea." Ika tries to drown him to show him up, but this in turn prevents him from reaching a kid trapped in a current, so Ika must save her herself. After witnessing a birthday party, Ika decides she wants one as well, so the Aizawa sisters hold a party for her before playing with some fireworks. Ika later meets Aiko’s friend Sanae Nagatsuki, who takes a creepy liking towards her and forces her to cosplay for her personal photo collection.
