latest site news


24.06.2026 gekiyaku.org is indefinitely broken as I convert the site into an SSI type of site. It should make pageload times a lot shorter and it will make the site easier for me to edit in general, but it will take a while until I'm done with it, and in the end it won't even have any noticeable difference for the viewer. The forlorn life of a #coder #developer...

30.05.2026 I have added the Pocket Bird widget to the site... It's a funny little birb that hops around the webpage. You can unlock new bird species by collecting feathers that sometimes fall from the sky. Normally these feathers have a chance to fall once every 2 hours, but I changed it to once every 20 minutes. Try to speedrun the pigeon unlockable toDAY!

29.03.2026 :: i think i'm finally happy with the blog display on the site. there is now an RSS feed display in the "news" tab and you can visit the dreamwidth blog its feed is from by clicking the "blog" tab on the header.

22.03.2026 :: officially launched the SHRINE RING WEBRING! look a bit below at the "webring" category in the sidebar and click the heart icon to learn how to join. please join. please

13.03.2026 :: i have added a light mode toggle for the website. most people and myself prefer dark modes on sites but there's people who are the opposite, so i made it out of consideration for my friend. the blog doesnt have a light mode toggle yet but i'll work on this next.

04.01.2026 :: game author stuff on the authors page now. Also I finally made it so that the font size toggler resizes text on the homepage properly. Sadly I can't get it to work for the links on the header of the website because it's an iframe and I need it to be an iframe.

24.12.2025 :: wtf it's 7am of christmas eve. Hey I added a new attachment to the site! Visit the BEARBLOG tab in navigation to read blog posts related to Hatoful and this site. I'm very proud because I made a custom theme for bearblog for it.

19.12.2025 :: i lost access to my sybillapandemia blog so i've created a new one and it's linked in the new "authors" tab. i'm also fixing obsolete javascripts here and there.

05.12.2024 :: added a Change Font Size button to some pages. pages with lots of text. it doesn't work best on the homepage but works good on the other pages ok. hugs and kisses.

11.19.2024 :: ADDITIONS TO THE LINK PAGE, many links to fansites. Fixed the ability to use the chatbox from mobile.

gekiyaku : 劇 薬 (hard drug)



  Welcome to GEKIYAKU
Pandemia's Hatoful Boyfriend Handbook.


This is a website dedicated to the highly acclaimed 2011 Visual Novel Hatoful Boyfriend by moa810.
Hatoful Boyfriend was a first of it's kind horror scifi thriller disguised as an April Fools otome game. This fact alone is hidden from sight so well, that most people have heard of Hatoful, but don't know that it's actually far more than a quick April Fools game.


There are a lot of subtle details and secrets hidden within the game and its sequel alone, but in order to get a full grasp of the worldbuilding, one has to actively seek out secondary released content, such as webcomics, Drama CDs, and lore drops from websites that can't be accessed anymore (such as Moa's Tumblr blog.)

Through a collaborative effort, over the course of a decade, fans of Hatoful have compiled the Hatoful Boyfriend Fandom Wiki. The goal of this website however, is much more personal. I want to compile a shorthand reference for lore, but since it's a passion project written by one person, Some of the things I put on here might be a liiiiittle biased. For as objective facts as possible, look at the Wiki. I am not Moa or affiliated with Moa - this is both a personal shrine dedicated to Hatoful, and maybe (maybe!) a useful site for fans of Hatoful.



why "gekiyaku"?

the how & why of gekiyaku

"Gekiyaku" is a Japanese term for a "powerful substance" or "hard drug", but from my understanding, it's more of a poetic phrase that appears in song lyrics and poems, and is associated with emotion and symbolism. It's a different impression than what the words "hard drug" give off in English.
My first meeting with the word was with Nagito Komaeda's beautiful Character Song, which is titled poison -gekiyaku-
Welll I think the word fits the themes of Hatoful Boyfriend as well. It's main themes are medicine and love and tragedy. And that's just the site's URL anyway. You can call the website itself "Pandemia's Hato Handbook" or "The site with the school map and game timeline on it" too.



archiving

hatoful's lost media

Hatoful Boyfriend is an indie game that never broke out into crazy mainstream popularity so there actually isn't a ton of media to go through. Pretty much all material that has to do with Hatoful, canon and fanon, official and fanmade, has been distributed online and through live events like anime cons... There's an added element of hosting sites slowly dying since 2011, (Moa's original Tumblr blog got hacked and all of its original posts have been wiped and replaced with spam by a bot), and social media is as unfriendly as possible (Moa has recently deleted/completely wiped all her posts from Twitter, everything even since pre-Hatoful days, and moved to Bluesky as a platform, to protect her posts from Twitter's AI scraping).


And I completely support those decisions tbh. So one of my plans for this website is to host rarer Hatoful graphics, while also not feeding robots. I can achieve this by hosting this site on Nekoweb, because it has special anti-AI measures in place.
