Ikka Dumb Rock Hohoemi no Bakudan Cover: BanG Dream Reimagines YuYu Hakusho

There are some anime songs that feel almost impossible to touch. “Hohoemi no Bakudan” is absolutely one of them. Better known to many international fans as “Smile Bomb,” Matsuko Mawatari’s legendary opening for YuYu Hakusho has been living in anime playlists since 1992, and its funky groove is so recognizable that even a few seconds can trigger a serious nostalgia attack. So when BanG Dream! introduced a new version performed by Ikka Dumb Rock!, I was immediately curious—and a little nervous.

Covering a classic like this is a dangerous game. Change too much and fans start asking why the original was touched at all; change too little and the whole thing feels like karaoke with a bigger production budget. Thankfully, Ikka Dumb Rock! finds a surprisingly comfortable middle ground. Their version understands what made the original special while giving the song enough personality to feel like an actual BanG Dream! performance rather than a simple recreation.

Why “Hohoemi no Bakudan” Still Hits So Hard

Before getting into the new arrangement, it is worth remembering why this song has survived for more than three decades. “Hohoemi no Bakudan” was released in 1992 as the opening theme for YuYu Hakusho, one of the defining shonen anime of its generation. Its combination of funk, pop, rock attitude, bright instrumental accents, and Mawatari’s distinctive vocal performance created an opening that felt completely different from many traditional anime themes of the era.

What I love about the song is that it never sounds overly dramatic despite belonging to a series packed with supernatural battles and tournament arcs. There is confidence in it, but also a playful looseness. That quality fits Yusuke Urameshi incredibly well: rebellious, sarcastic, energetic, but never completely consumed by the seriousness surrounding him. That personality is exactly what makes the song so difficult to reinterpret without losing its soul.

And this is where Ikka Dumb Rock! makes an interesting choice. Instead of trying to make the song sound “bigger” simply because it is a modern production, the arrangement leans into groove and personality. The result feels less like a museum piece and more like an old favorite being played by a completely different band.

Meet Ikka Dumb Rock!

Ikka Dumb Rock!, often associated with the Japanese name Ikkadanran, occupies a particularly interesting position within the BanG Dream! universe. The group consists of Suga Raika on lead guitar and vocals, Mahashi Miku on rhythm guitar and vocals, Yakura Yomogi on bass, Umezato Chieri on drums, and Shinomiya Shizuku on keyboards. Even before this cover, their identity was easy to distinguish from many of the other bands in the franchise.

The biggest musical hook is their dual-vocalist setup. Raika and Miku are not simply sharing a chorus here and there; the contrast between their voices becomes part of the band’s personality. That turns out to be particularly useful for “Hohoemi no Bakudan,” because it gives the song an extra layer of movement that the original solo performance obviously did not have.

The band’s name itself suggests a warm family gathering, and that idea comes through surprisingly well in the arrangement. The vocals frequently feel like a conversation rather than a single singer delivering a predetermined melody. Personally, I think this is one of the smartest ways the cover could have been approached, because it makes the reinterpretation feel connected to Ikka Dumb Rock!’s identity rather than simply connected to YuYu Hakusho.

The Funk Is Still the Heart of the Song

The biggest compliment I can give this cover is that it doesn’t forget the groove. That sounds obvious, but it matters enormously with “Hohoemi no Bakudan.” Strip away the funk character and you are left with a completely different song. Ikka Dumb Rock! keeps that rhythmic foundation alive while giving the production a cleaner and more modern edge.

The bass deserves particular attention. Yakura Yomogi’s playing gives the arrangement a strong rhythmic center, helping the track maintain the bouncing energy that made the original so memorable. Instead of treating the bass as something sitting quietly underneath the guitars, the arrangement allows it to participate in the song’s personality. For me, that is one of the details that makes this cover work.

The keyboards also contribute to the modernization without completely abandoning the retro flavor. Rather than simply copying the old-school horn and synth textures, Shinomiya Shizuku’s parts add a brighter contemporary layer. The guitars, meanwhile, bring enough crunch to remind listeners that this is a BanG Dream! band performance, not a straight recreation of a 1990s pop track.

Two Voices Make a Huge Difference

If there is one element that immediately separates this version from the original, it is the vocal arrangement. Raika and Miku trading lines gives the verses a completely different sense of motion. Instead of one voice carrying the listener through the entire section, the song constantly shifts between the two singers before bringing them together.

I particularly like what happens when their voices meet during the bigger sections. The harmonies make the familiar melody feel slightly new without forcing the arrangement into unnecessary vocal acrobatics. There is a sense that the band is having fun with the song, which is exactly what I want from a BanG Dream! cover.

It also creates an unexpected connection with the original anime. Yusuke’s world was full of rivalries, friendships, arguments, and unlikely partnerships, so the conversational quality of the new vocals feels strangely appropriate. It is not trying to imitate the attitude of the original singer. Instead, it translates that attitude into the musical language of Ikka Dumb Rock!

A Classic Anime Song Without the “Copy-Paste” Problem

One of my biggest concerns whenever a modern franchise revisits a famous anime opening is that the result can become too safe. There is a temptation to preserve every recognizable detail, essentially creating the same song with newer instruments. That may satisfy nostalgia for a few minutes, but it rarely gives fans a reason to return to the cover.

Ikka Dumb Rock! avoids that trap. The melody remains immediately recognizable, but the band’s own funk-rock personality is always present. You can hear the original DNA, but you can also hear why this particular BanG Dream! group was chosen to perform it.

That distinction matters because the best anime covers are not necessarily the most faithful ones. Sometimes the best cover is the one that makes you appreciate the original again while simultaneously giving you something new to enjoy. This version lands surprisingly close to that sweet spot.

Why BanG Dream! Fans Are Talking About It

The reaction surrounding the cover also makes sense from a broader franchise perspective. BanG Dream! has always been built around the idea that anime characters and music can exist as parts of the same evolving ecosystem. Bringing a famous YuYu Hakusho theme into that world creates an easy bridge between fans who grew up with classic shonen anime and players who discovered the franchise through modern rhythm games.

That cross-generational appeal is probably the most interesting thing about the release. A longtime YuYu Hakusho fan can hear the bassline and immediately recognize the song, while a newer BanG Dream! player may discover the original because they simply enjoyed Ikka Dumb Rock!’s interpretation. That is exactly what a great anime cover should accomplish.

The timing alongside the global rollout of BanG Dream! Our Notes also gives the song extra visibility. A recognizable classic can attract curious players who might not otherwise pay attention to a new band, while the band’s distinct sound gives longtime fans something beyond pure nostalgia. It is a pretty effective combination of franchise promotion and genuine musical fan service.

My Favorite Details in the Cover

• The dual vocals: Raika and Miku give the familiar melody a new personality.
• The bass-driven groove: The funky foundation remains one of the strongest parts of the arrangement.
• The modern production: The track sounds cleaner without becoming painfully sterile.
• The restraint: The arrangement changes enough to feel fresh without losing the identity of “Hohoemi no Bakudan.”

Is This the Definitive New Version of Smile Bomb?

I would not go that far, and honestly, I don’t think it needs to be. The original “Hohoemi no Bakudan” belongs to a very specific moment in anime history, and nothing can completely replace that experience. What Ikka Dumb Rock! has accomplished is more interesting: they have created a version that can exist alongside the classic rather than competing with it.

That is probably why the cover feels so satisfying. It respects the nostalgia without being trapped by it. The musicians clearly understand that fans are coming to this song with decades of memories attached, so instead of aggressively reinventing everything, they preserve the core groove and then build their own sound around it.

Final Thoughts

Ikka Dumb Rock!’s take on “Hohoemi no Bakudan” is exactly the kind of anime music crossover I enjoy seeing. It has enough respect for Matsuko Mawatari’s original performance to satisfy longtime YuYu Hakusho fans, but it also sounds unmistakably like a modern BanG Dream! band. The dual vocals, funky bass, punchy guitars, and sparkling keyboard work all contribute to a version that feels energetic instead of overly polished or nostalgic for nostalgia’s sake.

More importantly, the cover reminds us why classic anime songs continue to matter. A great theme does not really disappear when its anime finishes airing; it waits for another generation to discover it. “Hohoemi no Bakudan” has already survived more than 30 years, and Ikka Dumb Rock! gives it another excuse to blast through anime playlists all over again.

For me, that is the real victory here. This is not simply another rhythm-game cover designed to fill a playlist. It feels like a genuine conversation between two eras of anime music—and, judging by how naturally the two styles fit together, it is a conversation I would happily listen to again.
