Deep Sea Valentine: Endings Guide

This guide should help you get all 7 endings of Deep Sea Valentine, which also make up most of the achievements.

Introduction

Deep Sea Valentine is a little different from other dating sims, because the route isn’t determined by “affection points” or a similar stat mechanic. You’re free to say whatever you want to the other characters, and it won’t affect your chances of going on a date with them. This means it can be difficult to figure out what does affect the ending, though. That’s what this guide is for!I recommend you only read this guide after you already tried a few things yourself. It contains a few spoilers and is meant as a last resort to prevent you from growing frustrated with the game.

Relevant Choices

There are exactly three points in the game where your choice will affect the route you get:

return the sawfish to Moka / forget to do so
(this decision is finalized when you visit Tae’s house in the purple forest)
use chocolate on crab / keep it
exit the cave right away / turn back
(only relevant if sawfish wasn’t returned on time)

This should already give you everything you need to get all the endings on your own. For the fastest 100% run, just save the game right after freeing Tae, before making your choice for the crab, and when you’re given the opportunity to turn back in the cave.

Specific Routes

Here’s what you need to do to get the route you want:

return the sawfish to Moka
use chocolate on the crab

don’t return the sawfish
keep the chocolate
turn back in the cave

return the sawfish to Moka
keep the chocolate

don’t return the sawfish
use chocolate on the crab
exit the cave right away

don’t return the sawfish
keep the chocolate
exit the cave right away

Triche is both the hardest and easiest to romance. Aside from the “bad” ending, you could technically always end up dating her. Details in the next section.
