NEW BOOK ANNOUNCEMENT!

Cover art-work

On february, a new HoiHoi-San book was distributed during comitia 155: "Ichigeki sacchuu!! HoiHoi-San LEGACY single chapter edition sequence 1"

It included the first chapter of LEGACY, a reprint of HoiHoi-Busters + 2 new pages, and a B5 poster.

Following the release, Tanaka Kunihiko has been posting on his fanbox plans and progress reports on a second book. While the contents will be based on the original LEGACY manuscript, the story and art will be revised and updated.

It's expected to release this august for comitia 157 and will most likely also be avalible in online bookstores.

Please support this release and support the author if you can!

What?

Ichigeki Sacchuu!! HoiHoi-San is a series that spawned from a manga serialized in 2003, created by the illustrator/mangaka Tanaka Kunihiko. Since then, it has had an anime and a videogame adaptation, a sequel, and a notable line of action figures. For more information check out: What is ichigeki Sacchu!! HoiHoi-San?

Why?

Following the cancellation of the Tankobon release for the sequel, there has been little news of more material. Until recent years, with a sudden barrage of content: a new edition of the original manga, an one-shot spin-off, re-uploads of the sequel manga, Legacy, which has never been avalible outside the original serialization until now, and, of course, more action figures.

The average weeb outside Japan with a moderate interest in HoiHoi-San would be hard-pressed in becoming aware of these developments. That’s why I hope for this site to bring attention to the fact that HoiHoi-San is still alive and kicking (for the most part).

And, given the series state of semi-obscurity, and being more than 20 years old at this point, a lot of content has been lost to time or is outside the reach of those not living in Japan. That’s why this site also serves as a collection of most things related to HoiHoi-San.

Medium sized one

Cleaned up some stuff visually. A new logo that hopefully looks better. Changed the style of the Info, Links and Manga sections. Added counters to the Gallery, and some new images as well.

Updates will keep a slow pace for the foreseable future due to life stuff. And, besides that, I've been working on HoiHoi-San stuff unrelated to the site on the sidelines, look forward to that wayyy into the future.

Thanks for checking the site out, as always.

You hear about videogames?

Added a new article to the info section, learn all about the PS2 game! Added 2 new illustrations, one of which you are seeing right now. Thanks for sticking by, the slow-down of updates has been due to life stuff happening, as it tends to. But I have been pretty happy working and seeing the website come along, hopefully, I get more time for it :-)

2025-01-09

New batch of illustrations

Added more illustrations to the gallery, mostly reference sheets. Consider this the first wave of adding illustrations from the Tumblr blog to here.

2025-01-01

CSS fixes

Fixed the guestbook covering up the update log on mobile & made the footer fill up unused screen space. Also, changed the format of the update log dates since the ordering apparently didn't work with the new year. It's Y-M-D now.

2024-12-30

GuestBook, new illustrations and a few other things

Added a GuestBook (There ->), three new illustrations for the gallery, made the gallery itself display newer images first, added two new categories to the gallery Kimiko and Mutsumi, changed the css a bit. And a few other things I'm probably forgetting.
Have a happy new year!🎊

Images now work

The thumbnail images on the gallery have been de-crustified, let's see how well Neocities likes loading them. Also the images on the LEGACY manga section should actually load now.
Removed the PS2 assets page, I don't really wanna deal with external file hosts.

2024-12-07

Grand website pre-opening

Just uploading the website to Neocities to test stuff out. Still under heavy construction on some places.
