If someone told you that a pest control company would create a dating simulator where your handsome love interest turns into a muscular cockroach, you would probably laugh it off as a joke. But here we are in 2026, and Earth Corp (also known as Earth Chemical), one of Japan’s biggest insecticide manufacturers, actually did exactly that. The game is called Gokigen Lovely Days, and it has already racked up over 44 million views on social media.
Let that sink in for a moment. Forty-four million views. For a cockroach dating game. From an insecticide company.
What Is Gokigen Lovely Days?
Released on June 4, 2026 — Japan’s official Bug Day, a clever wordplay on the numbers six and four — Gokigen Lovely Days (or Goki-Love for short) is a free, browser-based dating simulator available for a limited time until September 3, 2026.
The name itself is a brilliant pun. Gokigen means to be in a good mood or high spirits in Japanese, while goki happens to be the first syllable of gokiburi — the Japanese word for cockroach. You can see where this is going.
Four Love Interests, One Bizarre Twist
The game follows the standard dating sim formula at first. You meet four attractive bachelors, each fitting a classic romance archetype:
- A clumsy prince — endearing and awkward
- An innocent younger brother type — sweet and pure
- A refined traditional gentleman — elegant and composed
- A wild older brother figure — bold and untamed
Sound normal? Here is where things get wild. Each character has bizarre preferences listed in their profiles — they love dark, damp spaces, beer, and onions, while absolutely hating mint, citrus, and lavender. These are not random quirks. They are literal descriptions of cockroach behavior. Every love interest is secretly modeled after a real cockroach species.
After texting back and forth for a few in-game days, each character offers either a surprise visit or a surprise gift delivered to your door. And that is when the infamous transformation scenes kick in. Out of a parcel. From below the sink. Crawling out of the kitchen vent. Each love interest reveals their true form — a muscular, anthropomorphic cockroach that would haunt your dreams forever.
The game ends immediately after each transformation, with the cockroach image fading out and being replaced by a bottle of insecticide. The message is brutally simple and incredibly effective.
Yuki Kaji Makes It Even More Unforgettable
Here is the detail that pushed this game into viral territory: all four cockroach characters are voiced by Yuki Kaji, one of Japan’s most famous voice actors. If that name does not ring a bell, he is the voice behind Eren Yeager in Attack on Titan, Shoto Todoroki in My Hero Academia, and Kenma Kozume in Haikyuu!!.
Imagine hearing one of the most beloved voices in anime history delivering sweet romantic dialogue — only to watch the speaker transform into a cockroach. One netizen perfectly captured the collective experience: The nice voice flustered me as much as the ultimate transformation shocked me.
The contrast between premium voice acting and the absurdity of the content is exactly what made this campaign so shareable. People did not just play the game — they shared their reactions, posted screenshots, and turned it into a cultural moment.
The Product Behind the Madness
Gokigen Lovely Days is not just a viral stunt — it is actually a marketing campaign for Earth Corp’s new product line called Gokish Su Sugoi Roach Killer. The product comes in an easy-push canister with 60, 120, and 160 push variations, plus a version with a pleasant minty fragrance. Despite being designed for cockroaches, it also works against bed bugs, dust mites, mosquitoes, and flies.
The game’s creepy-crawly hints — chittering sounds mixed into the background music, characters appearing out of nowhere and vanishing just as quickly, the player character showing discomfort when approached — all mirror the real-life experience of encountering cockroaches in your home. It is marketing disguised as entertainment, and honestly, it is genius.
A Campaign That Blew Up Beyond Expectations
Earth Corp’s X post announcing the game has amassed more than 44 million views. The company also ran a giveaway campaign where followers could win pest control gear and Gokigen Lovely Days acrylic character stands by reposting the campaign post — 64 winners were selected. An additional 10 winners were chosen from people who replied with their thoughts after playing.
This is not the first time Japan has experimented with bizarre dating sims. Remember the pigeon dating simulator Hatoful Boyfriend? Or the dating sim where you romance a man with an ice cream chocolate for a head? Japan’s gaming culture has a long history of taking the absurd and making it genuinely entertaining. But Gokigen Lovely Days takes the crown for 2026’s most creative marketing campaign by a wide margin.
What Do You Think?
Would you actually play Gokigen Lovely Days, or is the idea of dating a cockroach a bridge too far even for you? Is this the most creative ad campaign you have ever seen, or just pure chaos? And honestly — do you think other pest control companies should follow Earth Corp’s lead?
Drop your thoughts in the comments. We genuinely want to know if this was marketing brilliance or just pure madness. Either way, we cannot look away.
