Mori Calliope on how “Let’s Just Crash” Embodies the Rage of Gachiakuta

In anime,an opening theme isn’t just a vibe-it’s a thesis statement. Before a single line of dialogue hits viewers’ ears, that song sets a tone, teases an emotional arc, and lets fans know whether a show is gonna punch them in the gut or kick their heart in its ass. Basically, a good OP is a part of an anime’s holy trinity: art style, voice cast, and theme song. When it slaps, you don’t skip it; you sing along with it week in and week out.

Gachiakuta on Bridging the Gap Between VTubing and a Music Career

Gachiakuta recently held a solo concert earlier this year. But is there a connection between being a VTuber and a musician? It’s a question many in the virtual world are exploring.

In the VTubing world, peopel choose different paths. Some focus solely on music, while others prioritize streaming. Gachiakuta explains that focusing primarily on music is tough. It requires a dedication to original songs and covers, with streaming taking a backseat. Others focus on personality and streaming, creating character songs as a side project.

For gachiakuta, music always came first. “I was a musician before beginning this career, and I’ve always wanted it to be central to my image,” she says. But she also loves streaming, and feels it’s become a core part of who she is. She considers herself a hybrid artist.

Gachiakuta hopes her success opens doors for other virtual artists. Many VTubers take music seriously and work hard to create original content. She’s excited to see what opportunities will arise for the wider VTuber, virtual artist, and virtual singer community. She believes more virtual artists deserve these kinds of opportunities.
