Evaluation
Kaiju Princess launched on June 21, 2022 and has received substantial post-launch support from developer PantyParrot. The game received a major free 2.0 update on February 10, 2026, adding full Japanese and Chinese voiceovers, a new Bath Mode, and additional post-game travel events — delivering on a promise originally made in mid-2025 and formally rescheduled from Q4 2025 to Q1 2026 in December 2025. Follow-up bug fix patches (Ver. 2.1 and Ver. 2.11) shipped shortly after on February 10 and February 13, 2026.
On July 1, 2025, PantyParrot's 3rd Anniversary announcement for the series confirmed that Kaiju Princess 3 is in production, and that a new spinoff title — Kaiju Princess: Super Survivor Showdown, described as a brand-new action rogue game — is also now in development. These are direct developer statements about future entries in the Kaiju Princess universe, confirming the studio is actively building on the franchise.
The developer has been communicative and active, with the most recent news post on June 19, 2026 (announcing a related title in their lineup). PantyParrot has demonstrated consistent engagement with the Kaiju Princess property through updates, sequels, merchandise, and novel adaptations.

About this game
💟Kaiju Princess💟
You are an average, run-of-the-mill office worker who lives a drab and dull existence. Until... you get the balls to leave a message on a "homestay" website. This site is specially designed for women looking for a place to stay. Eager to meet your first visitor, you open the door and see a female wearing bizarre clothes, who claims to be a kaiju princess. Can anyone say... psycho?
Nevertheless, you two make a deal: You will provide shelter and basic necessities for the young lady, and the mysterious stranger will provide you with... *cough*... services.
Unfortunately, it soon becomes quite evident that the woman is indeed an alien invader. And to top it all off, she can summon kaijus and command them, which she does to carry out her mission... to destroy Earth! Even if you kick her out or manage to get her off the planet, the invaders will only send more ruthless kaijus to attack.
There's only one way to help save the planet: Make sure she meets the "minimum destruction requirements" set by her alien overlords. If you can do that, you can stave off utter annihilation. And thus, you join forces with the huge-titted kaiju princess.
Meet your destruction quotas in the time given and minimize damage and death in the city. At the same time, you need to make sure government agencies aren't onto you. There's only one thing that's more important than all that... living a great life and having fun with your hot kaiju companion!
