GALLERIA, the gaming PC brand from Thirdwave Corporation, ran a loud Tokyo Game Show 2026 booth in Exhibition Hall 2 and put its name on multiple VTuber and creator collaborations. On the hardware side, its Inaba Haneru collaboration desktop is on sale and a Dospara CPU upgrade campaign on four GALLERIA models runs through September 25.
GALLERIA's Tokyo Game Show 2026 booth at Makuhari Messe, Exhibition Hall 2, space 02-C21, was set two months before the event: a permanent REJECT collaboration corner with display units and playable demo stations, and a REJECT x GALLERIA special stage on the closing day, September 21, from 13:30 to 15:30. Vspo returned for a second consecutive year with the Vspo GG TGS2026 GALLERIA booth edition on September 20 in two sessions, 12:30 to 14:00 and 15:00 to 16:30. The booth calendar also listed a photographer talk session, NASEF JAPAN sessions, a DCP Agent Academy class, a MoniMoni DX TGS edition, a Stogram Radio special edition, and a DJ set by Kenmochi Hidefumi of Wednesday Campanella, plus current and upcoming models and a new product set to appear at the venue.
By the time the show opened, the booth's individual slots were being announced one by one. Vspo GG's travel edition filled September 20: Street Fighter 6 from 12:30, presented by GALLERIA, and VALORANT from 15:00, supported by Riot Games. Mother3 VS Akarin Monimoni DX, hosted by streamer Mother3 and Vspo VTuber Akari Yumeno with streamer Kettsun as guest, got its first stage event, Monimoni DX TGS2026 Special Edition, on September 19 from 11:00 to 12:00, streamed on the show's YouTube channel and handing out stickers with a key visual drawn by Shiro Manta while supplies last.
The hardware announcements ran on their own track. Thirdwave began selling the Inaba Haneru collaboration model on September 10, 2026, at Dospara stores and the Dospara online store: a pillarless case printed with an original illustration by Tatehata Dan, a heart-shaped side window, Inaba Haneru's logo on the liquid cooling head, orange interior lighting at her request, plus a newly recorded system voice, an original mouse cursor, and two wallpapers. Eight configurations run from 344,980 yen to 704,980 yen, split between AMD Ryzen and Intel Core Ultra models with GeForce RTX 5060, 5060 Ti, 5070, and 5080 cards. On September 11, Dospara opened a CPU Customization Campaign on four GALLERIA desktops, letting buyers switch from a Ryzen 7 9800X3D to a Ryzen 7 9850X3D for 50 yen, with GeForce RTX 5070 and RTX 5080 configurations eligible, through September 25 at 10:59 AM. The GALLERIA XDR7A-R57-GD, with Ryzen 7 9800X3D, RTX 5070 12GB, 32GB DDR5, and a 1TB Gen4 SSD, starts at 414,980 yen.

Thirdwave began sales on September 29, 2026 of six renewed GALLERIA gaming PC models made with Kagura Nana, who works as an illustrator and V-artist. The machines use a specially designed PC case built around visuals that Kagura Nana supervised herself, and the renewed lineup also brings upgraded specs compared with the previous collaboration models. Thirdwave runs GALLERIA as its gamer-oriented PC brand, and the company opened a special page for the collaboration. The announcement covers the redesign of an existing collaboration line rather than a wholly new product family, with the case artwork and the internal hardware both changed for this release. Pricing, individual model names, and ship dates were not included in the material released alongside the announcement.
