Created page with "== Patch Notes == * Patch adding new content released on May 25. ** Movement with WASD keys added in response to feedback about mouse-only movement. ** Lesbian H-scenes added...."

New page

== Patch Notes ==
* Patch adding new content released on May 25.
** Movement with WASD keys added in response to feedback about mouse-only movement.
** Lesbian H-scenes added. Female characters with the "likes women" trait can now be seen having lesbian H-scenes around school. However, since it's not a threesome, the protagonist cannot participate—only observe. If the female characters are not in a lewd state, they may notice the protagonist's gaze and flee if approached carelessly (e.g., using Shift or Z key).
*** Adding the "lewd bitch" and "likes women" traits to all female students turns the school into a [[nymphomania|nymphomaniac asylum]]. They engage in acts in open areas like the [[school entrance]] or [[hallway]], not just secluded spots like the infirmary or restroom. After school, they can be seen doing this endlessly. If two female students are in one place, there's a high chance...
** Non-con H-scenes with teachers added.

* Details regarding the large free update scheduled for June 29 (released June 1):
** Saturdays are no longer combined with holidays and revert to regular school days where students wear casual clothes. The schedule changes from "Fri → Holiday → Mon" back to "Fri → Sat → Sun → Mon."
** A special H-location added to the infirmary. If the protagonist sleeps on the infirmary bed and has had H-experience with an NPC (H-degree ≥50%) or if Rina-sensei is in the infirmary before sleeping (2+ H-scenes), she may visit randomly to provide services. --This means taking longer to lie down for quick saves!--
** New sex positions added:
*** "Hurdle Onani" added to the gym storage.
*** "Vault Back" special H-point added to the gym storage map.
*** "Missionary" special H-point added to the men's staff restroom.
** Other additions: New hairstyles, clothes, and accessory parts.

* Update on July 28:
** New personality trait "Easygoing" added.
** Sleeping on the rooftop bench may attract an NPC (with H-experience and H-degree ≥50%) randomly to provide services. Similar to the infirmary, but the math teacher appears instead of the nurse.
** Other additions: New sex positions and studio-related updates.

* Updates in August, October, and November–December:
** Swimsuits, Halloween, and Santa outfits added.

* Details regarding the After School update released on December 21, 2018:
** New locations added: Amusement park, subway, park, etc. (available only after the first date).
** New H-scenes including threesomes [* Possible during lesbian H-scenes via interruptions].
** New intimacy system related to the protagonist (marriage system).
** Save data expansion (up to 100 slots).
** Maximum character count increased (from 38 to 99! However, without the KoikatuGameplayMod 1.2 update, the in-school character limit remains 38).
** Limited-time outfits added.
** New personality traits: "S-type nerves," "Returned girl," "Dialect girl," "Cold girl."
** NPCs near H-scenes react with shy motions and flee.
** System explanations added.

* Details regarding the Darkness update released on May 24, 2019:
** New "Darkness Points" added to the third floor.
** New H-scenes including threesome motions [* Available at Darkness Points].

* No mention of post-scenario features such as recurring main characters, new 3D motions, or new clubs/classes.

* The official site announced new update directions [* Limited to dates]. If implemented well, this could cover many previously criticized aspects. Users often rely on mods like kPlug's free H-maps, Koikatsu Free H Map, COM3D2 H-Maps, More H-Maps, and Project Diva H-Maps Collection for additional content.

* The next title, ''[[Koikatsu Emotion Creators]]'', included Koikatsu Darkness as a pre-order bonus for reservations made between March 1–18, 2019. Only '''6 out of many personalities''' [* Traditional heroine, innocent, cool straightforward, ojousama, hesitant, easygoing] received dedicated events and H-voices, along with 3 outfits [* Tortoise-shell bondage, sexy sweater, qipao], H-scenes, studio items, and motions.

* On June 10, 2019, ''Koikatsu Party'' was released on Steam, but as of July 25, 2020, it is '''region-locked and unavailable in South Korea''' [* Steam version only compatible with the foreign "Berry Pack"]. Due to Illusion's termination of activities on August 18, 2023, it is currently unobtainable on Steam as of 2025. The price was ₩68,390. The Steam version initially lacks a story mode, requiring installation of a [[http://koikatsuparty.illusion.jp/|dedicated patch for the overseas version]] [* Only compatible with the North American Steam version; the April 9, 2021 patch is not recommended due to severe conflicts].

* On May 14, 2021, the DLC for Steam ''Koikatsu Party'' titled "After Party" was released on Steam, but South Korea remains '''region-locked and unavailable'''. The price of the DLC is ₩62,000, nearly as expensive as the base game. Despite the name, the DLC is functionally identical to After School.

* On May 28, 2021, information about the sequel ''[[Koikatsu Sunshine]]'' was announced and pre-orders began. [[https://twitter.com/ILLUSION_staff/status/1395591995280674818|Official Illusion Twitter link]]

* Summary of the Koikatsu Sunshine demo trailer released on May 28, 2021:
** New personality trait "Inclusive" brings total traits to over 40.
** Over 130 sex positions.
** Certain objects during island exploration can be used as keywords in affection level events (e.g., mountain cat).
** Oil massages (esthe) possible with a lover at high affection.
