- Rather than repeating the new-song introduction, this article organizes the official video flow from Shorts to the live video.

Snackgirls editor note
Kirari: “After showing a precise glimpse through Shorts first, having the stage video follow right away makes the flow really easy to follow. It is a structure where the live video answers people who became curious from the short clips.”
Red: “I like that yesterday’s reveal and today’s reveal move in the same direction. Right now, more than the title, the key point is what kind of energy this song has on stage.”
What was newly released?
CUTIE STREET’s official YouTube channel released the Error404♡ Yoyogi National Gymnasium live video on July 11. If the first official Short posted the day before offered a brief impression of the song, this video lets viewers see how it continues through the expressions and movement of the actual stage.
In particular, this update is different because it is not just an automatically continuing Shorts flow, but a new central video built around the live performance. For fans, it adds material that lets them immediately check “how the song looks on an actual stage.”

How does it connect to the previous day’s Shorts?
On July 10, the first official Error404♡ Short was released first, and on July 11, an additional Short giving a quick look at the same song’s mood arrived alongside the live video. This flow is satisfying not simply because the number of videos increased, but because the order of short clip → stage check is clear.
The Shorts quickly capture one scene’s expressions and key choreography, while the live video shows the overall stage energy and audience response. That makes this release a stage-side follow-up check to the first Shorts flow covered in the previous day’s article.

Why it works as fan content
For IDOL visual content, what matters often is not a single thumbnail, but the order in which multiple official videos build up. This CUTIE STREET flow is not a simple repetition of the new song’s title; the Shorts and the live video each play different roles.
The newly added Yoyogi live video shows the scale of the stage and the feeling of being there, while the Shorts from the same period briefly highlight expressions, point choreography, and fan response. The noteworthy point in this morning roundup was that the official videos alone now form a package showing how one song is currently being presented.

Game Sunakku-style wrap-up
This CUTIE STREET update is less a major comeback announcement or added music-release information, and more an update where the official video flow expands into confirmation of the actual stage. If the first Short from the day before created the song’s first impression, the July 11 Yoyogi live video shows how that impression comes alive on stage.
So the point to check now is simple. If you have only seen Error404♡ through short Shorts clips, watching this live video as well makes the song’s stage tone much clearer. In the next cycle, it will be worth watching whether additional stage videos or official photos for the same song are added.
