VTuber Unit V.W.P. Releases Opening and Ending Theme Songs for KAMITSUBAKI CITY UNDER CONSTRUCTION Anime
The virtual artist collective V.W.P. (Virtual Witch Phenomenon) has officially released music videos for both the opening and ending theme songs of the new summer 2025 anime KAMITSUBAKI CITY UNDER CONSTRUCTION. Known for their distinct vocals and artistic storytelling, the five-member Virtual YouTuber unit brings their music and voice acting talents together in this mixed-media anime project.
Opening Theme “Utahime” Delivered as V.W.P.’s 24th Digital Single
On July 4, V.W.P. debuted the track “Utahime” (English title: “DIVA”) as their 24th digital single, accompanied by a full-length music video released on their official YouTube channel. The dynamic track has been selected as the opening theme song for KAMITSUBAKI CITY UNDER CONSTRUCTION, and a creditless version of the anime’s opening featuring “Utahime” is also available publicly.
The song’s powerful arrangement and emotionally charged lyrics reflect the anime’s post-apocalyptic yet hopeful narrative, making it a fitting introduction to the series. A physical CD single containing “Utahime” was subsequently released in Japan on July 30.
Ending Theme “Tsuioku” Featured in Episode 0
The anime’s Episode 0 featured the unit’s 25th digital single “Tsuioku” (English title: “Chase the Day”) as its ending theme. Released digitally on July 9, the song explores themes of memory, loss, and resilience. V.W.P. followed up with a music video release for “Tsuioku” on their official YouTube channel, offering a visual narrative that parallels the emotional stakes of the anime’s storyline.
Both “Utahime” and “Tsuioku” are also included on the July 30 CD single release, allowing fans to enjoy both tracks in high quality via physical and digital formats.
