Houshou Marine's name is attached to a figure line for February 2027, a made-to-order varsity jacket shipping early 2027, a card with art by Kentaro Yabuki, and an EP released September 30. She is one of five talents set for the HoloCozy desktop game within 2026.
Marine's 2026 slate runs through other people's products as much as her own. Bandai Spirits is making her a prize figure in the hololive IF line, paired with the Crossbone Gundam X1 in Nui Armor style, with colored prototypes shown on August 27 and crane game deployment set for February 2027. The same Gundam x hololive production collaboration has a METAL ROBOT Soul line, though its named entries are for Sakura Miko and Hoshimachi Suisei, not Marine. TOKYO TOY SHOW 2026 showed an RG Crossbone Gundam X1 [Houshou Marine Ver.] at the Bandai booth.
The merchandise spread continued into apparel and print. VTee's "Dead Ma'am's Chest" varsity jacket, designed around the 2024 song "Ghost Ship Battle," took made-to-order orders from September 12 to October 3 at 132,000 yen including tax, with delivery from late January to around March 2027. It was the closing item of the VTee x hololive Collection, which launched in August with pieces for four hololive members. In the same month, the V Jump October Issue carried a Houshou Marine HoloCa card drawn by Kentaro Yabuki, plus a conversation between Yabuki and Marine.
She also appears in the HoloCozy desktop game. The free Steam demo, out from holo Indie, is limited to Tokino Sora, but the full version, set for 2026, names Marine among five pixel-art talents alongside Usada Pekora, Shiranui Flare, and Shirogane Noel. Marine's own release is the EP 'New World Carnival,' due September 30 in three editions, whose four tracks include 'BooooM!!!,' the ending theme for 'Magilumiere Co. Ltd.' Season 2.
