Welcome to my achievement guide for YIIK. Hopefully this will help you fully complete this game.

A few notes before we get started:

This game unlocks achievements on closing the game. This is quite annoying, so if you think you earned an achievement and don't see it, save and quit.

Turn on assist mode in config. This doesn't prevent you from getting any achievements, but it makes the combat system WAY nicer.

Make a separate savegame here to unlock both endings in one playthrough
The following achievements are unmissable in a normal playthrough, so you don't have to worry about them much.

Friend of Small Animals

Elevator Girl Goes Missing

Mild Gains

A Mysterious Girl

Serve No Bodacious Master!

You Kids Can Just Go Home

What Did I Do To Deserve This?

These achievements are for doing various things in combat - and are MUCH easier if you have assist mode on.


Amateur MC - Perform 10 Combos on Alex's standard attack.

Master MC - Perform 25 Combos on Alex's standard attack.

Easier once you get a few upgrades for Alex, so the record spins 3+ times instead of the 2 times the first 2 weapons spin. I was able to get this with assist mode and the Strolling Bonez LP, though it was tricky.

Trigger Happy - Perform 25 Combos with LP Toss ability.


Modern Ronin - Execute 1000 Slashes ability with Claudio.

The Essentia 2000

Android Agility - Perform 15 Combos on The Essentia 2000's standard attack.


Expert Hunter - Clear every monster den.
