Abyss School Guide | How To Unlock All YuHee Outfits

A guide on how to get all the YuHee outfits in Abyss School.

Game Guide by Sabi on Mar 10, 2025

YuHee (Yu-Hee), the protagonist in Abyss School, has several outfits that you can get by advancing in-game, updating, and unique in-game conditions.

Some of these outfits are unlocked naturally as you progress through the storyline, while others require you to complete side content, special events, or post-game quests. This walkthrough will teach you how to get all the outfits.

Default School Uniform

Abyss School Guide, Default School Uniform

YuHee begins the game in her school outfit: a black skirt and red ribbon on a white top. The outfit becomes increasingly disheveled when she takes damage in-game.

YuHee's torn school outfit can be unlocked as she takes damage, and various levels of destruction reflect her troubles in the abyss.

Swimsuit Costume

Abyss School Guide, Swimsuit Costume

The navy blue one-piece swimsuit was added in version 1.2v. The costume is accessed after completing a special event within the school pool area. If you miss the event on your first playthrough, it is still accessible in post-game DLC.

The swimsuit, like the school uniform, goes through three stages of deterioration that gradually alter its appearance.

Gym Uniform

Abyss School Guide, Gym Uniform

The gym costume, which consists of a white T-shirt trimmed in red and shorts, is obtained by fulfilling all of the side quests in Floor 3 of the Abyss. They consist of having a conversation with specific NPCs and answering tiny riddles before handing them over to you.

Like the other costumes, the gym uniform has a damage progression effect that changes when YuHee suffers damage.

Cat Shirt Costume

Abyss School Guide, Cat Shirt Costume

The CatShirt costume is an invisible garment acquired by finishing a secret activity on Floor 5. To start this activity, find a cat-related item and talk to a secret NPC that provides information regarding the costume.

The CatShirt is a relaxed, loose-fitting T-shirt with a cute cat design. Unlike all other attire, it does not have visible damage and is completely cosmetic.

High Society School Uniform

Abyss School Guide, High Society School Uniform

The High Society School Uniform is a more refined version of YuHee's default uniform. This costume was added to a post-launch DLC update and can be obtained after finishing the New Game+ secret ending.

The uniform doesn't affect gameplay, but it is a stylish option for players who prefer a more refined appearance.

Maid Outfit (DLC Only)

Abyss School Guide, Maid Outfit (DLC Only)

The maid outfit is included in a paid DLC pack. Once the DLC is installed, it will also be available to buy at the in-game shop. YuHee appears Victorian-era inspired in this classic black-and-white maid uniform with an apron.

Using this outfit results in some small speech changes, but they do not impact the overall storyline. The maid uniform, like other clothing, has minute damage variations, though not as much as the school uniform.
