Singer Sou has released the full music video for "Hello," his digital single serving as the opening theme for the fall 2026 isekai anime So What's Wrong with Getting Reborn as a Goblin?, Crunchyroll News reported Monday. The video landed on Sou's official YouTube channel, and the song itself has been out digitally since October 6.

Who's who

If the voice sounds familiar, it should. Sou is one of the quiet workhorses of anime music: he started out uploading covers to Nico Nico Douga in 2013, went major in 2015, and has steadily built an anime-theme résumé that includes "Mister Fixer" for ID: INVADED (2020), "Nero" for Dead Mount Death Play (2023), "Tada, Kimi no Mamade" for ZENSHU (2025) and "Q.E.D." for The Case Book of Arne (2026), per Crunchyroll News.

For "Hello," he clearly connected with the material beyond a work-for-hire gig. In a comment published on the anime's official website and quoted by Crunchyroll News, he explained what drew him in:

"The theme song 'Hello' is a track that depicts living out the time given to each of us in a changing world and eventually coming across someone. I sang this song with great care, weaving it together with the story of the work."

He added that he was struck by how the goblins, "living their limited and short lives," move forward alongside the protagonist — which is a lot of emotional weight for a series whose title reads like a shrug.

The show behind the song

Don't let the title fool you into expecting a pure gag series. The anime adapts the manga by Nazuna Miki (story) and Tsukasa Araki (art), and the premise has a melancholy engine under the comedy: office worker Akira Yagami dies saving a child and wakes up in another world as a weak goblin — a species with a brutally short natural lifespan. His unique skill extends his own years and lets him inherit the abilities of fallen goblins, setting up a climb toward becoming the strongest in a world of demons and elves, per Crunchyroll's synopsis.

The production side, as reported by Crunchyroll News:

  • Director: Ryota Kawahara (Dragon Ball DAIMA episode director) at studio BAKKKA
  • Series composition: Yuichiro Momose (So I'm a Spider, So What?)
  • Character designs: Hiroyuki Saita (Revue Starlight)
  • Music: Takenoko Boy, with Hiroto Morishita as sound director

Where to watch

The series premiered in Japan on October 5, 2026, and Crunchyroll streams it across North and South America, Europe, Africa, Oceania, the Middle East, and much of Asia. The "Hello" MV gives the show's themes a second doorway — and given Sou's track record of elevating mid-season anime with sticky openings, it's worth the three minutes.
