Eipu's Hanbunko Gets a New Ichimaru MV Version Featuring Original Characters

Hanbunko (はんぶんこ), a song created by Eipu, has received a new visual interpretation. On September 13, 2026, illustrator and video creator Ichimaru confirmed that they worked on the newly released “Hanbunko [Ichimaru Version]” music video, which is now available on YouTube.

The new upload carries a different context from Eipu's public Hatsune Miku and Kasane Teto MV released in June. Its description explains that Eipu was commissioned to create an original song for the uploader's original characters, while Ichimaru was commissioned to produce the MV, making the September release a separate visual presentation of the same song.

Hanbunko Ichimaru Version and Eipu's Original MV

Ichimaru Directly Confirms Their Role on the New MV

Ichimaru's official post provides a direct confirmation of who created the latest video.

In the September 13 post, Ichimaru states that they worked on the MV and encourages followers to watch it, linking directly to “Hanbunko [Ichimaru Version]” on YouTube.

That role is consistent with Ichimaru's official portfolio, where they describe themselves as someone who creates illustrations and videos.

Ichimaru can therefore be clearly credited as the MV creator without extending that credit into unverified roles such as songwriting, composition or vocals.

The Song Originates From an Original-Character Project

The description of the new YouTube upload adds an important piece of context.

It states that Eipu created an original song for the uploader's original characters, while Ichimaru was commissioned to make the music video.

That helps explain the “Ichimaru Version” label. The September video represents one visual treatment of the song, placing those original characters at the center of its presentation.

The owner's name and complete character information are not added as firm metadata here because they were not clearly verifiable in the accessible sources.

What is clear is the production relationship: Eipu handled the music, while Ichimaru created this MV.

Eipu Previously Released a Hatsune Miku and Kasane Teto Version

Before the Ichimaru MV appeared, Eipu released a public version titled “Hanbunko / Hatsune Miku & Kasane Teto” on June 12, 2026.

That version uses Hatsune Miku and Kasane Teto as its virtual singers.

For the public MV, Kusajirou is credited with artwork and storyboards, while Tsukisaki handled the video.

Eipu's own description also notes that Hanbunko was a song they had provided for another project, giving additional context to the idea that the Miku-Teto video represents Eipu's public interpretation of a song with an existing original-character background.

The September MV therefore does not replace the June version. They are two distinct visual presentations of the same underlying song.

The Digital Single Arrived on June 19

One week after Eipu's public YouTube MV, Hanbunko received its digital music release on June 19, 2026.

Official TuneCore Japan metadata credits Eipu as the artist, lyricist, composer, producer, mixing engineer, mastering engineer and guitarist.

The audio side of the project is therefore strongly centered on Eipu.

The project's public timeline can be separated into three clear stages:

• June 12: Eipu's public MV featuring Hatsune Miku and Kasane Teto
• June 19: Hanbunko's digital single release
• September 13: Hanbunko Ichimaru Version MV

There is currently no verified announcement that the September MV uses a newly recorded or separately released audio version.

The Word “Hanbunko” Carries Two Opposing Ideas

Eipu provides an interesting piece of context for the title はんぶんこ in the original upload.

The creator points out that the concept can connect to both “Share” and “Split” in English—ideas that can feel almost opposite, one emphasizing sharing something together and the other dividing something apart.

The original upload also uses “Sharing” directly beneath the Japanese title.

That duality fits a song built around conflicting emotions such as love and hate, happiness and bitterness, and the desire to remain connected through a relationship that is anything but simple.

Rather than reproducing the lyrics themselves, that creator commentary is enough to show why the apparently simple title carries multiple directions of interpretation.

The New MV Expands the Song Visually Rather Than Replacing It

The September release is especially interesting because it gives the same music another visual identity.

Eipu's public MV centers Miku and Teto through the visual work of Kusajirou and Tsukisaki. The newer version instead uses original characters and Ichimaru's visual direction.

The primary difference is therefore in how the song's world is presented.

There is no verified information indicating that its composition or lyrics were rewritten specifically for the Ichimaru Version. Calling it an alternate / commissioned MV version is therefore more accurate than describing it as a remix or a new song.

The two videos can now be viewed side by side as separate visual readings of the same music rather than competing versions in which one replaces the other.

Why This Matters

1) The song now has two clearly different visual identities

Eipu's version uses Hatsune Miku and Kasane Teto, while Ichimaru's version brings the original-character context of the project to the foreground.

2) Ichimaru contributes a dedicated visual interpretation

This is more than a thumbnail or character swap: Ichimaru is directly credited with making the MV.

3) The commission background clarifies the song's history

The latest description shows that Hanbunko did not originate solely as a Miku-Teto song. Eipu had created it for an original-character project before publishing a public version.

4) The title itself leaves room for multiple interpretations

Eipu's “share” and “split” observation gives Hanbunko a duality that becomes even more interesting now that the song has more than one visual treatment.

Closing

For now, the September 13 release is presented as a new MV version rather than a separate single or remix. Further character information or additional interpretations of the project will depend on future updates from its creators.
