The player takes the role of an Octoling, shown to be in "what has become of" Inkopolis Square, the central area of the game.

Characters

 * Unknown Octoling
 * Unknown Inkling (assumable through trailer footage)

Teaser
The teaser trailer for Side Order features a slow pan across a dull, stark white version of Inkopolis Square from, focusing on an unknown Octoling character. The Octoling wears their hair in the Tentacurl hairstyle, their ink color is a faded brown, and they are dressed in a short-sleeved white jumpsuit with matching white knee-high boots, as well as a thin, translucent brace on their left forearm. Throughout the trailer various cryptic static images and short clips briefly flicker on-screen; the images primarily depict the Octoling in strange bright white locations, as well as Off the Hook, while the clips seemingly depict biological components such as cells, blood, or organs. The ground appears to be coated in a thick layer of snow, and bits of snow-like specks can also be seen floating in the distance. Branches of presumed dead or bleached coral are present throughout the plaza. Deca Tower looks significantly different in its blanched out state, resembling a normal building with various billboards affixed to it rather than a battle tower. The tower's entrance is entirely different, and the Great Zapfish is absent from its resting spot. A swarm of fish swim towards the Octoling towards the end.

A dull, slightly out-of-tune music box melody with steady electronic percussion accompanies the teaser, which slowly grows more intense; towards the end, Marina can be heard speaking.

Trivia

Etymology
A side order is another term for a side dish, a food item meant to accompany a larger main item as part of a meal. The title is likely a pun on Team Order, the team that lost the Final Fest in and was supported by Marina.
