Honkai: Star Rail Hatsune Miku Robin Medley MV Out Now

Hatsune Miku and Robin Drop a Surprise Medley

The Honkai: Star Rail community woke up to something unexpected this week: a full music video collaboration between Hatsune Miku and Summeretto Robin. Titled "Summeretto Medley: Tell Your World x Only by Chasing the Wind," the MV is now available worldwide on the official Hatsune Miku YouTube channel.

For those who follow Honkai: Star Rail news, this crossover is a big deal. It's not every day that a Vocaloid icon shares the stage with a Halovian diva, and the result is a medley that blends two very different musical identities into one cohesive performance.

A Message from Miku

Ahead of the release, the Vocaloid account shared a special message from Hatsune Miku speaking in English. She congratulated the Summeretto Robin alt on her new Honkai: Star Rail song, "Only by Chasing the Wind," and complimented it while comparing it to Robin's usual energy. Miku then announced the medley, which combines her own "Tell Your World" with Robin's new track.

The announcement tweet, posted on 2026-09-04, teased the collaboration and set the premiere time. The medley itself is a seamless blend of two songs that, on paper, shouldn't work together—but somehow do.

The Songs Behind the Medley

"Tell Your World"

Vocaloid producer kz released "Tell Your World" in March 2012. The song is a meta-commentary on Miku's desire—or the Vocaloid community's desire—to connect with the world through her music. It was originally created for a Japanese Google Chrome commercial, which helped propel it to iconic status among Vocaloid fans.

"Only by Chasing the Wind"

"Only by Chasing the Wind" debuted in Version 4.5 of Honkai: Star Rail. Players who have Robin Summeretto hear it every time she uses her Ultimate. Like all of Robin's other songs, Chevy performs it regardless of which language your game is set to.

This isn't the first time Honkai: Star Rail has collaborated with Hatsune Miku. Previous crossover songs include "Memi Memi Myun Myun" and "HoYoHoYo ni Shite Ageru ♪," both of which were well-received by the community.

Why This Matters for Players

From a purely gameplay perspective, this collaboration doesn't change any mechanics. Robin Summeretto remains a top-tier Harmony unit, and her Ultimate's song is purely cosmetic. However, the collaboration is a reminder of how HoYoverse continues to blur the lines between in-game content and real-world music culture.

For players who care about the lore and aesthetic of Honkai: Star Rail, this medley adds another layer to Robin's identity as a cosmic pop star. It also strengthens the bond between the Honkai community and the broader Vocaloid fandom, which can only be good for the game's longevity.

Previous Collaborations

Honkai: Star Rail and Hatsune Miku have teamed up before. The first collaboration, "Memi Memi Myun Myun," was a playful track that showcased Miku's signature vocals alongside the game's characters. The second, "HoYoHoYo ni Shite Ageru ♪," continued the trend with a more upbeat, festival-style song.

Both songs were released as part of special events and were met with positive reception from both fanbases. The new medley builds on that momentum, offering a more ambitious fusion of two distinct musical styles.

Final Thoughts

The Summeretto Medley is a treat for fans of both Honkai: Star Rail and Hatsune Miku. It's a well-produced MV that highlights the strengths of both songs and the vocal talents of Chevy and Miku. While it doesn't impact gameplay, it's a nice reminder that Honkai: Star Rail is more than just a game—it's a multimedia experience.

Honkai: Star Rail is available now on PS5, Windows PC, and mobile devices.
