宝鐘マリン (Houshou Marine)‘s BooooM!!!, the ending theme for Season 2 of TV anime 株式会社マジルミエ (Kabushiki Gaisha Majirumie), has been out and climbing the charts for a while now — but this week it finally got its official music video. For a song that’s already found an audience purely on sound, giving it a proper animated visual is the last piece falling into place.
A Song That Already Proved Itself
BooooM!!! didn’t need a music video to start racking up serious numbers — it built momentum as an anime ending theme first, the kind of song that gets people searching it out before any official visual exists. That makes this MV less of an introduction and more of a victory lap for a track that already earned its spot.
A Full Studio Production
The MV comes from bees inc., with direction, storyboarding, and filming from みずみ (Mizumi), character design and animation direction from もふじろ〜。(Mofujiro), and a genuinely large key animation team behind it. That’s a studio-level production behind a VTuber song, not a quick single-artist visual — which matches the anime-tie-in scale the song was always operating at.
Written for Chaos, On Purpose
Lyrics come from q*Left, with composition and arrangement by Giga — a name known for exactly the kind of high-energy, slightly unhinged pop songwriting BooooM!!! delivers. Pairing Marine’s larger-than-life pirate-captain persona with a composer who specializes in barely-controlled chaos is a strong match, and it shows in how well the song’s energy has already translated into chart performance.
Why the MV Matters Now
A late MV release for an already-successful song is a different kind of event than a debut drop — it’s a chance to give an established hit a second wave of attention, and a full studio-animated video is exactly the kind of push that can do it. For fans who’ve been listening without visuals this whole time, this is the moment the song finally gets its full picture.
