What is Koikatsu!? How to add character cards

Four girls in front of a school building with the Koikatsu! logo

The official genre of Koikatsu! is 3DキャラメイクH恋愛シミュレーション. Release is 27 April 2018. You spend school life and H with girls made in character design. The game itself is no longer sold.

What is Koikatsu!?

The official story starts when the protagonist, living alone near an aunt after his father is transferred overseas, transfers into the girls’ school where the aunt is principal. In a school with a lopsided sex ratio, the コイカツ部 starts with the heroines.

You make a school ID with the school name, emblem (23 kinds), the protagonist’s name, and nicknames (205 kinds), then edit the class. Saved character cards and random registration from the online character uploader can be used.

Girls move around campus and spend the day studying, eating, listening to music, or in club activities according to personality. There are toilets and showers, and you can peek.

Talking and listening lets you recruit into the コイカツ部 or confess and become lovers. Confession fails if you are not close enough. Communication includes コイバナ and 世間話, and character-creation questions change the reactions.

The campus is a 3D map with classrooms, club rooms, the staff room, a pool, and more. As lovers you get dates, H at home after returning, and being woken in bed in the morning. Up to 38 people can be registered.

H is not only for lovers. When a girl’s mood is high, a body-only relationship is possible without being lovers. H with teachers as well as students is included. There is a story mode and フリーH.

Mouse actions cover touching, pulling, licking, fingering, and thrusting. States run from virgin to 淫乱, and reactions change with personality and state. You can touch breasts and hips during insertion, and positions change as she gets used to H.

Koikatsu! Trilogy Pack

Koikatsu! Trilogy Pack package listing the base game and two extras

A set of the base game, the personality pack, and アフタースクール. Most cards use the extra data; missing data breaks hair and outfits. Cards other people share often assume the Trilogy Pack as well.

アフタースクール and the personality pack are both in the Trilogy Pack. Do not install them twice.

Sunshine cards usually do not load in the Trilogy Pack. For the format difference, see What is Koikatsu! Sunshine? Converting character cards.

Character cards

A character card is an image that holds character-creation data. Loading volunteer cards lets you animate characters from anime, manga, games, light novels, and VTuber avatars.

From initial settings, choose 「コイカツ キャラメイクのキャラフォルダを開く」. Save cards in the female folder that opens. You are done when the card appears for 座席表 転入 or キャラメイク キャラ読み込み.

Scene data is an image that recreates a situation. Load it in CHARA STUDIO.

File format

Example of a character-card PNG

Cards are PNG. A JPEG or other format with the same look will not load.

The default size is 252×352. Larger cards exist. Sizes such as 756×1056 keep the same aspect ratio.

pixiv cards

The normally displayed pixiv image has the character data removed. Click the image and save the expanded original PNG.

If screenshots are posted together, click すべてを見る first, then save each original.

There is no card

If there is no card image, it may be on an external uploader. Check the description first. Some creators put uploader or SNS URLs on their profile.

If there is no link either, distribution may have stopped. Do not comment or message the creator to ask for a re-upload.

Google Drive cards

The preview does not contain character data. Use the download button at the top right.

Hair or costumes do not load

Some cards use mods. Without those mods, the character may not match the preview. Environment changes can also make a correct load impossible. If it will not load, you may need to substitute other parts.

The card will not load

A card missing personality data can freeze Confirm/Back after 転入 on the 座席表. A black icon on the student-ID image and the セクシー personality are typical signs.

Personalities Sッ気, 無感情, 方言娘, and 帰国子女 need アフタースクール. 勝ち気, 誠実, and 艶やか need the personality pack. Both are in the Trilogy Pack.

Changing the personality in キャラメイク will at least make the game operable. You cannot change it from 座席表 character edit.

If none of the above apply, the card may be a Sunshine card. Size and format match, but the default frame says Sunshine. The Trilogy Pack usually cannot load those cards.
